CWE CWE-400
CAPEC
  • XML Ping of the Death
    An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.
  • XML Entity Expansion
    An attacker submits an XML document to a target application where the XML document uses nested entity expansion to produce an excessively large output XML. XML allows the definition of macro-like structures that can be used to simplify the creation of complex structures. However, this capability can be abused to create excessive demands on a processor's CPU and memory. A small number of nested expansions can result in an exponential growth in demands on memory.
  • Inducing Account Lockout
    An attacker leverages the security functionality of the system aimed at thwarting potential attacks to launch a denial of service attack against a legitimate system user. Many systems, for instance, implement a password throttling mechanism that locks an account after a certain number of incorrect log in attempts. An attacker can leverage this throttling mechanism to lock a legitimate user out of their own account. The weakness that is being leveraged by an attacker is the very security feature that has been put in place to counteract attacks.
  • Violating Implicit Assumptions Regarding XML Content (aka XML Denial of Service (XDoS))
    XML Denial of Service (XDoS) can be applied to any technology that utilizes XML data. This is, of course, most distributed systems technology including Java, .Net, databases, and so on. XDoS is most closely associated with web services, SOAP, and Rest, because remote service requesters can post malicious XML payloads to the service provider designed to exhaust the service provider's memory, CPU, and/or disk space. The main weakness in XDoS is that the service provider generally must inspect, parse, and validate the XML messages to determine routing, workflow, security considerations, and so on. It is exactly these inspection, parsing, and validation routines that XDoS targets. There are three primary attack vectors that XDoS can navigate Target CPU through recursion: attacker creates a recursive payload and sends to service provider Target memory through jumbo payloads: service provider uses DOM to parse XML. DOM creates in memory representation of XML document, but when document is very large (for example, north of 1 Gb) service provider host may exhaust memory trying to build memory objects. XML Ping of death: attack service provider with numerous small files that clog the system. All of the above attacks exploit the loosely coupled nature of web services, where the service provider has little to no control over the service requester and any messages the service requester sends.

    description Ephemeral association time spoofing additional protection ntpd in ntp 4.2.x before 4.2.8p7 and 4.3.x before 4.3.92 allows authenticated users that know the private symmetric key to create arbitrarily-many ephemeral associations in order to win the clock selection of ntpd and modify a victim's clock via a Sybil attack. This issue exists because of an incomplete fix for CVE-2016-1549 .(CVE-2018-7170) Interleaved symmetric mode cannot recover from bad state ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the 'received' timestamp, which allows remote attackers to cause a denial of service (disruption) by sending a packet with a zero-origin timestamp causing the association to reset and setting the contents of the packet as the most recent timestamp.

    description Multiple vulnerabilities have been discovered in the NTP suite : CVE-2016-9311: Trap crash, Reported by Matthew Van Gundy of Cisco ASIG. CVE-2016-9310: Mode 6 unauthenticated trap information disclosure and DDoS vector. Reported by Matthew Van Gundy of Cisco ASIG. CVE-2016-7427: Broadcast Mode Replay Prevention DoS.

CVE-2016-7434: NULL pointer dereference in _IO_str_init_static_internal(). Reported by Magnus Stubman. CVE-2016-7426: Client rate limiting and server responses. Reported by Miroslav Lichvar of Red Hat. CVE-2016-7433: Reboot sync calculation problem. Reported independently by Brian Utterback of Oracle, and by Sharon Goldberg and Aanchal Malhotra of Boston University. Impact : A remote attacker who can send a specially crafted packet to cause a NULL pointer dereference that will crash ntpd, resulting in a Denial of Service. [CVE-2016-9311] An exploitable configuration modification vulnerability exists in the control mode (mode 6) functionality of ntpd. If, against long-standing BCP recommendations, 'restrict default noquery ...' is not specified, a specially crafted control mode packet can set ntpd traps, providing information disclosure and DDoS amplification, and unset ntpd traps, disabling legitimate monitoring by an attacker from remote. [CVE-2016-9310] An attacker with access to the NTP broadcast domain can periodically inject specially crafted broadcast mode NTP packets into the broadcast domain which, while being logged by ntpd, can cause ntpd to reject broadcast mode packets from legitimate NTP broadcast servers. [CVE-2016-7427] An attacker with access to the NTP broadcast domain can send specially crafted broadcast mode NTP packets to the broadcast domain which, while being logged by ntpd, will cause ntpd to reject broadcast mode packets from legitimate NTP broadcast servers. [CVE-2016-7428] Origin timestamp problems were fixed in ntp 4.2.8p6. However, subsequent timestamp validation checks introduced a regression in the handling of some Zero origin timestamp checks. [CVE-2016-7431] If ntpd is configured to allow mrulist query requests from a server that sends a crafted malicious packet, ntpd will crash on receipt of that crafted malicious mrulist query packet. [CVE-2016-7434] An attacker who knows the sources (e.g., from an IPv4 refid in server response) and knows the system is (mis)configured in this way can periodically send packets with spoofed source address to keep the rate limiting activated and prevent ntpd from accepting valid responses from its sources. [CVE-2016-7426] Ntp Bug 2085 described a condition where the root delay was included twice, causing the jitter value to be higher than expected. Due to a misinterpretation of a small-print variable in The Book, the fix for this problem was incorrect, resulting in a root distance that did not include the peer dispersion. The calculations and formulas have been reviewed and reconciled, and the code has been updated accordingly. [CVE-2016-7433]

(CVE-2016-7426) * A flaw was found in the control mode functionality of ntpd. A remote attacker could send a crafted control mode packet which could lead to information disclosure or result in DDoS amplification attacks. (CVE-2016-9310) * A flaw was found in the way ntpd implemented the trap service. A remote attacker could send a specially crafted packet to cause a NULL pointer dereference that will crash ntpd, resulting in a denial of service. (CVE-2016-9311) * A flaw was found in the way ntpd running on a host with multiple network interfaces handled certain server responses. A remote attacker could use this flaw which would cause ntpd to not synchronize with the source. (CVE-2016-7429) * A flaw was found in the way ntpd calculated the root delay. A remote attacker could send a specially crafted spoofed packet to cause denial of service or in some special cases even crash. (CVE-2016-7433)

    NASL id NTP_4_2_8P9.NASL
    description The version of the remote NTP server is 4.x prior to 4.2.8p9. It is, therefore, affected by the following vulnerabilities : - A denial of service vulnerability exists when rate limiting is configured for all associations, the limits also being applied to responses received from the configured sources. An unauthenticated, remote attacker can exploit this, by periodically sending spoofed packets, to keep rate limiting active, resulting in valid responses not being accepted by ntpd from its sources. (CVE-2016-7426) - A denial of service vulnerability exists in the broadcast mode replay prevention functionality. An unauthenticated, adjacent attacker can exploit this, via specially crafted broadcast mode NTP packets periodically injected into the broadcast domain, to cause ntpd to reject broadcast mode packets from legitimate NTP broadcast servers. (CVE-2016-7427) - A denial of service vulnerability exists in the broadcast mode poll interval functionality. An unauthenticated, adjacent attacker can exploit this, via specially crafted broadcast mode NTP packets, to cause ntpd to reject packets from a legitimate NTP broadcast server. (CVE-2016-7428) - A denial of service vulnerability exists when receiving server responses on sockets that correspond to different interfaces than what were used in the request. An unauthenticated, remote attacker can exploit this, by sending repeated requests using specially crafted packets with spoofed source addresses, to cause ntpd to select the incorrect interface for the source, which prevents it from sending new requests until the interface list is refreshed. This eventually results in preventing ntpd from synchronizing with the source. (CVE-2016-7429) - A flaw exists that allows packets with an origin timestamp of zero to bypass security checks. An unauthenticated, remote attacker can exploit this to spoof arbitrary content. (CVE-2016-7431) - A flaw exists due to the root delay being included twice, which may result in the jitter value being higher than expected. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2016-7433) - A denial of service vulnerability exists when handling specially crafted mrulist query packets that allows an unauthenticated, remote attacker to crash ntpd. (CVE-2016-7434) - A flaw exists in the control mode (mode 6) functionality when handling specially crafted control mode packets. An unauthenticated, adjacent attacker can exploit this to set or disable ntpd traps, resulting in the disclosure of potentially sensitive information, disabling of legitimate monitoring, or DDoS amplification. (CVE-2016-9310) - A NULL pointer dereference flaw exists in the report_event() function within file ntpd/ntp_control.c when the trap service handles certain peer events. An unauthenticated, remote attacker can exploit this, via a specially crafted packet, to cause a denial of service condition. (CVE-2016-9311) - A denial of service vulnerability exists when handling oversize UDP packets that allows an unauthenticated, remote attacker to crash ntpd. Note that this vulnerability only affects Windows versions. (CVE-2016-9312)

  • NASL family Huawei Local Security Checks
    NASL id EULEROS_SA-2017-1024.NASL
    description According to the versions of the ntp packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - It was found that when ntp is configured with rate limiting for all associations the limits are also applied to responses received from its configured sources. A remote attacker who knows the sources can cause a denial of service by preventing ntpd from accepting valid responses from its sources. (CVE-2016-7426) - A flaw was found in the control mode functionality of ntpd. A remote attacker could send a crafted control mode packet which could lead to information disclosure or result in DDoS amplification attacks. (CVE-2016-9310) - A flaw was found in the way ntpd implemented the trap service. A remote attacker could send a specially crafted packet to cause a null pointer dereference that will crash ntpd, resulting in a denial of service. (CVE-2016-9311) - A flaw was found in the way ntpd running on a host with multiple network interfaces handled certain server responses. A remote attacker could use this flaw which would cause ntpd to not synchronize with the source. (CVE-2016-7429) - A flaw was found in the way ntpd calculated the root delay. A remote attacker could send a specially-crafted spoofed packet to cause denial of service or in some special cases even crash. (CVE-2016-7433) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
