Vulnerabilities > CVE-2016-7426 - Resource Exhaustion vulnerability in multiple products
Attack vector
NETWORK Attack complexity
LOW Privileges required
NONE Confidentiality impact
NONE Integrity impact
NONE Availability impact
HIGH Summary
NTP before 4.2.8p9 rate limits responses received from the configured sources when rate limiting for all associations is enabled, which allows remote attackers to cause a denial of service (prevent responses from the sources) by sending responses with a spoofed source address.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (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.

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.
