Exploitability:
CWE CWE-264
CAPEC
  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

    description From Red Hat Security Advisory 2010:0088 : Updated kvm packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. KVM is a Linux kernel module built for the standard Red Hat Enterprise Linux kernel. The x86 emulator implementation was missing a check for the Current Privilege Level (CPL) and I/O Privilege Level (IOPL). A user in a guest could leverage these flaws to cause a denial of service (guest crash) or possibly escalate their privileges within that guest. (CVE-2010-0298, CVE-2010-0306) A flaw was found in the Programmable Interval Timer (PIT) emulation. Access to the internal data structure pit_state, which represents the data state of the emulated PIT, was not properly validated in the pit_ioport_read() function. A privileged guest user could use this flaw to crash the host. (CVE-2010-0309) A flaw was found in the USB passthrough handling code. A specially crafted USB packet sent from inside a guest could be used to trigger a buffer overflow in the usb_host_handle_control() function, which runs under the QEMU-KVM context on the host. A user in a guest could leverage this flaw to cause a denial of service (guest hang or crash) or possibly escalate their privileges within the host. (CVE-2010-0297) This update also fixes the following bugs : * pvclock MSR values were not preserved during remote migration, causing time drift for guests. (BZ#537028) * SMBIOS table 4 data is now generated for Windows guests. (BZ#545874) * if the qemu-kvm '-net user' option was used, unattended Windows XP installations did not receive an IP address after reboot. (BZ#546562) * when being restored from migration, a race condition caused Windows Server 2008 R2 guests to hang during shutdown. (BZ#546563) * the kernel symbol checking on the kvm-kmod build process has a safety check for ABI changes. (BZ#547293) * on hosts without high-res timers, Windows Server 2003 guests experienced significant time drift. (BZ#547625) * in some situations, installing Windows Server 2008 R2 from an ISO image resulted in a blue screen 'BAD_POOL_HEADER' stop error. (BZ#548368) * a bug in the grow_refcount_table() error handling caused infinite recursion in some cases. This caused the qemu-kvm process to hang and eventually crash. (BZ#552159) * for Windows Server 2003 R2, Service Pack 2, 32-bit guests, an 'unhandled vm exit' error could occur during reboot on some systems. (BZ#552518) * for Windows guests, QEMU could attempt to stop a stopped audio device, resulting in a 'snd_playback_stop: ASSERT playback_channel->base.active failed' error. (BZ#552519) * the Hypercall driver did not reset the device on power-down. (BZ#552528) * mechanisms have been added to make older savevm versions to be emitted in some cases. (BZ#552529) * an error in the Makefile prevented users from using the source RPM to install KVM. (BZ#552530) * guests became unresponsive and could use up to 100% CPU when running certain benchmark tests with more than 7 guests running simultaneously. (BZ#553249) * QEMU could terminate randomly with virtio-net and SMP enabled. (BZ#561022) All KVM users should upgrade to these updated packages, which contain backported patches to resolve these issues. Note: The procedure in the Solution section must be performed before this update will take effect.

    description USN-947-1 fixed vulnerabilities in the Linux kernel. Fixes for CVE-2010-0419 caused failures when using KVM in certain situations. This update reverts that fix until a better solution can be found. We apologize for the inconvenience. It was discovered that the Linux kernel did not correctly handle memory protection of the Virtual Dynamic Shared Object page when running a 32-bit application on a 64-bit kernel. A local attacker could exploit this to cause a denial of service. (Only affected Ubuntu 6.06 LTS.) (CVE-2009-4271) It was discovered that the r8169 network driver did not correctly check the size of Ethernet frames. A remote attacker could send specially crafted traffic to crash the system, leading to a denial of service. (CVE-2009-4537) Wei Yongjun discovered that SCTP did not correctly validate certain chunks. A remote attacker could send specially crafted traffic to monopolize CPU resources, leading to a denial of service. (Only affected Ubuntu 6.06 LTS.) (CVE-2010-0008) It was discovered that KVM did not correctly limit certain privileged IO accesses on x86. Processes in the guest OS with access to IO regions could gain further privileges within the guest OS. (Did not affect Ubuntu 6.06 LTS.) (CVE-2010-0298, CVE-2010-0306, CVE-2010-0419) Evgeniy Polyakov discovered that IPv6 did not correctly handle certain TUN packets. A remote attacker could exploit this to crash the system, leading to a denial of service. (Only affected Ubuntu 8.04 LTS.) (CVE-2010-0437) Sachin Prabhu discovered that GFS2 did not correctly handle certain locks. A local attacker with write access to a GFS2 filesystem could exploit this to crash the system, leading to a denial of service. (CVE-2010-0727) Jamie Strandboge discovered that network virtio in KVM did not correctly handle certain high-traffic conditions. A remote attacker could exploit this by sending specially crafted traffic to a guest OS, causing the guest to crash, leading to a denial of service. (Only affected Ubuntu 8.04 LTS.) (CVE-2010-0741) Marcus Meissner discovered that the USB subsystem did not correctly handle certain error conditions. A local attacker with access to a USB device could exploit this to read recently used kernel memory, leading to a loss of privacy and potentially root privilege escalation. (CVE-2010-1083) Neil Brown discovered that the Bluetooth subsystem did not correctly handle large amounts of traffic. A physically proximate remote attacker could exploit this by sending specially crafted traffic that would consume all available system memory, leading to a denial of service. (Ubuntu 6.06 LTS and 10.04 LTS were not affected.) (CVE-2010-1084) Jody Bruchon discovered that the sound driver for the AMD780V did not correctly handle certain conditions. A local attacker with access to this hardward could exploit the flaw to cause a system crash, leading to a denial of service. (CVE-2010-1085) Ang Way Chuang discovered that the DVB driver did not correctly handle certain MPEG2-TS frames. An attacker could exploit this by delivering specially crafted frames to monopolize CPU resources, leading to a denial of service. (Ubuntu 10.04 LTS was not affected.) (CVE-2010-1086) Trond Myklebust discovered that NFS did not correctly handle truncation under certain conditions. A local attacker with write access to an NFS share could exploit this to crash the system, leading to a denial of service. (Ubuntu 10.04 LTS was not affected.) (CVE-2010-1087) Al Viro discovered that automount of NFS did not correctly handle symlinks under certain conditions. A local attacker could exploit this to crash the system, leading to a denial of service. (Ubuntu 6.06 LTS and Ubuntu 10.04 LTS were not affected.) (CVE-2010-1088) Matt McCutchen discovered that ReiserFS did not correctly protect xattr files in the .reiserfs_priv directory. A local attacker could exploit this to gain root privileges or crash the system, leading to a denial of service. (CVE-2010-1146) Eugene Teo discovered that CIFS did not correctly validate arguments when creating new files. A local attacker could exploit this to crash the system, leading to a denial of service, or possibly gain root privileges if mmap_min_addr was not set. (CVE-2010-1148) Catalin Marinas and Tetsuo Handa discovered that the TTY layer did not correctly release process IDs. A local attacker could exploit this to consume kernel resources, leading to a denial of service. (CVE-2010-1162) Neil Horman discovered that TIPC did not correctly check its internal state. A local attacker could send specially crafted packets via AF_TIPC that would cause the system to crash, leading to a denial of service. (Ubuntu 6.06 LTS was not affected.) (CVE-2010-1187) Masayuki Nakagawa discovered that IPv6 did not correctly handle certain settings when listening. If a socket were listening with the IPV6_RECVPKTINFO flag, a remote attacker could send specially crafted traffic that would cause the system to crash, leading to a denial of service. (Only Ubuntu 6.06 LTS was affected.) (CVE-2010-1188) Oleg Nesterov discovered that the Out-Of-Memory handler did not correctly handle certain arrangements of processes. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2010-1488). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

(BZ#552159) * for Windows Server 2003 R2, Service Pack 2, 32-bit guests, an 'unhandled vm exit' error could occur during reboot on some systems. (BZ#552518) * for Windows guests, QEMU could attempt to stop a stopped audio device, resulting in a 'snd_playback_stop: ASSERT playback_channel->base.active failed' error. (BZ#552519) * the Hypercall driver did not reset the device on power-down. (BZ#552528) * mechanisms have been added to make older savevm versions to be emitted in some cases. (BZ#552529) * an error in the Makefile prevented users from using the source RPM to install KVM. (BZ#552530) * guests became unresponsive and could use up to 100% CPU when running certain benchmark tests with more than 7 guests running simultaneously. (BZ#553249) * QEMU could terminate randomly with virtio-net and SMP enabled. (BZ#561022) All KVM users should upgrade to these updated packages, which contain backported patches to resolve these issues. Note: The procedure in the Solution section must be performed before this update will take effect.

    title CentOS 5 : kvm (CESA-2010:0088)
  • NASL family Ubuntu Local Security Checks
    NASL id UBUNTU_USN-947-1.NASL
    description It was discovered that the Linux kernel did not correctly handle memory protection of the Virtual Dynamic Shared Object page when running a 32-bit application on a 64-bit kernel. A local attacker could exploit this to cause a denial of service. (Only affected Ubuntu 6.06 LTS.) (CVE-2009-4271) It was discovered that the r8169 network driver did not correctly check the size of Ethernet frames. A remote attacker could send specially crafted traffic to crash the system, leading to a denial of service. (CVE-2009-4537) Wei Yongjun discovered that SCTP did not correctly validate certain chunks. A remote attacker could send specially crafted traffic to monopolize CPU resources, leading to a denial of service. (Only affected Ubuntu 6.06 LTS.) (CVE-2010-0008) It was discovered that KVM did not correctly limit certain privileged IO accesses on x86. Processes in the guest OS with access to IO regions could gain further privileges within the guest OS. (Did not affect Ubuntu 6.06 LTS.) (CVE-2010-0298, CVE-2010-0306, CVE-2010-0419) Evgeniy Polyakov discovered that IPv6 did not correctly handle certain TUN packets. A remote attacker could exploit this to crash the system, leading to a denial of service. (Only affected Ubuntu 8.04 LTS.) (CVE-2010-0437) Sachin Prabhu discovered that GFS2 did not correctly handle certain locks. A local attacker with write access to a GFS2 filesystem could exploit this to crash the system, leading to a denial of service. (CVE-2010-0727) Jamie Strandboge discovered that network virtio in KVM did not correctly handle certain high-traffic conditions. A remote attacker could exploit this by sending specially crafted traffic to a guest OS, causing the guest to crash, leading to a denial of service. (Only affected Ubuntu 8.04 LTS.) (CVE-2010-0741) Marcus Meissner discovered that the USB subsystem did not correctly handle certain error conditions. A local attacker with access to a USB device could exploit this to read recently used kernel memory, leading to a loss of privacy and potentially root privilege escalation. (CVE-2010-1083) Neil Brown discovered that the Bluetooth subsystem did not correctly handle large amounts of traffic. A physically proximate remote attacker could exploit this by sending specially crafted traffic that would consume all available system memory, leading to a denial of service. (Ubuntu 6.06 LTS and 10.04 LTS were not affected.) (CVE-2010-1084) Jody Bruchon discovered that the sound driver for the AMD780V did not correctly handle certain conditions. A local attacker with access to this hardward could exploit the flaw to cause a system crash, leading to a denial of service. (CVE-2010-1085) Ang Way Chuang discovered that the DVB driver did not correctly handle certain MPEG2-TS frames. An attacker could exploit this by delivering specially crafted frames to monopolize CPU resources, leading to a denial of service. (Ubuntu 10.04 LTS was not affected.) (CVE-2010-1086) Trond Myklebust discovered that NFS did not correctly handle truncation under certain conditions. A local attacker with write access to an NFS share could exploit this to crash the system, leading to a denial of service. (Ubuntu 10.04 LTS was not affected.) (CVE-2010-1087) Al Viro discovered that automount of NFS did not correctly handle symlinks under certain conditions. A local attacker could exploit this to crash the system, leading to a denial of service. (Ubuntu 6.06 LTS and Ubuntu 10.04 LTS were not affected.) (CVE-2010-1088) Matt McCutchen discovered that ReiserFS did not correctly protect xattr files in the .reiserfs_priv directory. A local attacker could exploit this to gain root privileges or crash the system, leading to a denial of service. (CVE-2010-1146) Eugene Teo discovered that CIFS did not correctly validate arguments when creating new files. A local attacker could exploit this to crash the system, leading to a denial of service, or possibly gain root privileges if mmap_min_addr was not set. (CVE-2010-1148) Catalin Marinas and Tetsuo Handa discovered that the TTY layer did not correctly release process IDs. A local attacker could exploit this to consume kernel resources, leading to a denial of service. (CVE-2010-1162) Neil Horman discovered that TIPC did not correctly check its internal state. A local attacker could send specially crafted packets via AF_TIPC that would cause the system to crash, leading to a denial of service. (Ubuntu 6.06 LTS was not affected.) (CVE-2010-1187) Masayuki Nakagawa discovered that IPv6 did not correctly handle certain settings when listening. If a socket were listening with the IPV6_RECVPKTINFO flag, a remote attacker could send specially crafted traffic that would cause the system to crash, leading to a denial of service. (Only Ubuntu 6.06 LTS was affected.) (CVE-2010-1188) Oleg Nesterov discovered that the Out-Of-Memory handler did not correctly handle certain arrangements of processes. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2010-1488). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
