Impact:
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 The remote host is affected by the vulnerability described in GLSA-201003-01 (sudo: Privilege escalation) Multiple vulnerabilities have been discovered in sudo: Glenn Waller and neonsignal reported that sudo does not properly handle access control of the 'sudoedit' pseudo-command (CVE-2010-0426). Harald Koenig reported that sudo does not properly set supplementary groups when using the 'runas_default' option (CVE-2010-0427). Impact : A local attacker with privileges to use 'sudoedit' or the privilege to execute commands with the 'runas_default' setting enabled could leverage these vulnerabilities to execute arbitrary code with elevated privileges. Workaround : CVE-2010-0426: Revoke all 'sudoedit' privileges, or use the full path to sudoedit. CVE-2010-0427: Remove all occurrences of the 'runas_default' setting.

ESXi userworld update for ntp The Network Time Protocol (NTP) is used to synchronize the time of a computer client or server to another server or reference time source. A vulnerability in ntpd could allow a remote attacker to cause a denial of service (CPU and bandwidth consumption) by using MODE_PRIVATE to send a spoofed (1) request or (2) response packet that triggers a continuous exchange of MODE_PRIVATE error responses between two NTP daemons. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-3563 to this issue. c. Service Console package openssl updated to 0.9.8e-12.el5_4.1 OpenSSL is a toolkit implementing SSL v2/v3 and TLS protocols with full-strength cryptography world-wide. A memory leak in the zlib could allow a remote attacker to cause a denial of service (memory consumption) via vectors that trigger incorrect calls to the CRYPTO_cleanup_all_ex_data function. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-4355 to this issue. A vulnerability was discovered which may allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of computation required is still large. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-2409 to this issue. This update also includes security fixes that were first addressed in version openssl-0.9.8e-12.el5.i386.rpm. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the names CVE-2009-0590, CVE-2009-1377, CVE-2009-1378, CVE-2009-1379, CVE-2009-1386 and CVE-2009-1387 to these issues. d. Service Console update for krb5 to 1.6.1-36.el5_4.1 and pam_krb5 to 2.2.14-15. Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography. Multiple integer underflows in the AES and RC4 functionality in the crypto library could allow remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code by providing ciphertext with a length that is too short to be valid. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-4212 to this issue. The service console package for pam_krb5 is updated to version pam_krb5-2.2.14-15. This update fixes a flaw found in pam_krb5. In some non-default configurations (specifically, where pam_krb5 would be the first module to prompt for a password), a remote attacker could use this flaw to recognize valid usernames, which would aid a dictionary-based password guess attack. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-1384 to this issue. e. Service Console package bind updated to 9.3.6-4.P1.el5_4.2 BIND (Berkeley Internet Name Daemon) is by far the most widely used Domain Name System (DNS) software on the Internet. A vulnerability was discovered which could allow remote attacker to add the Authenticated Data (AD) flag to a forged NXDOMAIN response for an existing domain. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0097 to this issue. A vulnerability was discovered which could allow remote attackers to conduct DNS cache poisoning attacks by receiving a recursive client query and sending a response that contains CNAME or DNAME records, which do not have the intended validation before caching. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0290 to this issue. A vulnerability was found in the way that bind handles out-of- bailiwick data accompanying a secure response without re-fetching from the original source, which could allow remote attackers to have an unspecified impact via a crafted response. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0382 to this issue. NOTE: ESX does not use the BIND name service daemon by default. f. Service Console package gcc updated to 3.2.3-60 The GNU Compiler Collection includes front ends for C, C++, Objective-C, Fortran, Java, and Ada, as well as libraries for these languages GNU Libtool's ltdl.c attempts to open .la library files in the current working directory. This could allow a local user to gain privileges via a Trojan horse file. The GNU C Compiler collection (gcc) provided in ESX contains a statically linked version of the vulnerable code, and is being replaced. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-3736 to this issue. g. Service Console package gzip update to 1.3.3-15.rhel3 gzip is a software application used for file compression An integer underflow in gzip's unlzw function on 64-bit platforms may allow a remote attacker to trigger an array index error leading to a denial of service (application crash) or possibly execute arbitrary code via a crafted LZW compressed file. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0001 to this issue. h. Service Console package sudo updated to 1.6.9p17-6.el5_4 Sudo (su 'do') allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments. When a pseudo-command is enabled, sudo permits a match between the name of the pseudo-command and the name of an executable file in an arbitrary directory, which allows local users to gain privileges via a crafted executable file. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0426 to this issue. When the runas_default option is used, sudo does not properly set group memberships, which allows local users to gain privileges via a sudo command. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2010-0427 to this issue.

    description This update fixes two security issues : - CVE-2010-0427:CVSS v2 Base Score: 6.6 Sudo failed to properly reset group permissions, when 'runas_default' option was used. If a local, unprivileged user was authorized by sudoers file to perform their sudo commands under default user account, it could lead to privilege escalation CVE-2010-0426:CVSS v2 Base Score: 6.6 A privilege escalation flaw was found in the way sudo used to check file paths for pseudocommands. If local, unprivileged user was authorized by sudoers file to edit one or more files, it could lead to execution of arbitrary code, with the privileges of privileged system user (root).

    description CVE-2010-0426 sudo: sudoedit option can possibly allow for arbitrary code execution CVE-2010-0427 sudo: Fails to reset group permissions if runas_default set A privilege escalation flaw was found in the way sudo handled the sudoedit pseudo-command. If a local user were authorized by the sudoers file to use this pseudo-command, they could possibly leverage this flaw to execute arbitrary code with the privileges of the root user. (CVE-2010-0426) The sudo utility did not properly initialize supplementary groups when the 'runas_default' option (in the sudoers file) was used. If a local user were authorized by the sudoers file to perform their sudo commands under the account specified with 'runas_default', they would receive the root user's supplementary groups instead of those of the intended target user, giving them unintended privileges. (CVE-2010-0427)

  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DSA-2006.NASL
    description Several vulnerabilities have been discovered in sudo, a program designed to allow a sysadmin to give limited root privileges to users. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2010-0426 It was discovered that sudo when a pseudo-command is enabled, permits a match between the name of the pseudo-command and the name of an executable file in an arbitrary directory, which allows local users to gain privileges via a crafted executable file. - CVE-2010-0427 It was discovered that sudo when the runas_default option is used, does not properly set group memberships, which allows local users to gain privileges via a sudo command.
