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.

An unauthenticated, remote attacker can exploit this, via large OCSP Status Request extensions, to exhaust memory resources, resulting in a denial of service condition. (CVE-2016-6304) - A flaw exists in the SSL_peek() function in rec_layer_s3.c due to improper handling of empty records. An unauthenticated, remote attacker can exploit this, by triggering a zero-length record in an SSL_peek call, to cause an infinite loop, resulting in a denial of service condition. (CVE-2016-6305) - A denial of service vulnerability exists in the state-machine implementation due to a failure to check for an excessive length before allocating memory. An unauthenticated, remote attacker can exploit this, via a crafted TLS message, to exhaust memory resources. (CVE-2016-6307) - A denial of service vulnerability exists in the DTLS implementation due to improper handling of excessively long DTLS messages. An unauthenticated, remote attacker can exploit this, via a crafted DTLS message, to exhaust available memory resources. (CVE-2016-6308) - A flaw exists in the GOST ciphersuites due to the use of long-term keys to establish an encrypted connection. A man-in-the-middle attacker can exploit this, via a Key Compromise Impersonation (KCI) attack, to impersonate the server. last seen 2020-06-01 modified 2020-06-02 plugin id 93816 published 2016-09-30 reporter This script is Copyright (C) 2016-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/93816 title OpenSSL 1.1.0 < 1.1.0a Multiple Vulnerabilities code # # (C) Tenable Network Security, Inc. # include("compat.inc"); if (description) { script_id(93816); script_version("1.8"); script_cvs_date("Date: 2019/11/14"); script_cve_id( "CVE-2016-6304", "CVE-2016-6305", "CVE-2016-6307", "CVE-2016-6308" ); script_bugtraq_id( 93149, 93150, 93151, 93152 ); script_name(english:"OpenSSL 1.1.0 < 1.1.0a Multiple Vulnerabilities"); script_summary(english:"Performs a banner check."); script_set_attribute(attribute:"synopsis", value: "The remote service is affected by multiple vulnerabilities."); script_set_attribute(attribute:"description", value: "According to its banner, the remote host is running a version of OpenSSL 1.1.0 prior to 1.1.0a.

It is, therefore, affected by multiple vulnerabilities : - Multiple integer overflow conditions exist in the OpenSSL component in s3_srvr.c, ssl_sess.c, and t1_lib.c due to improper use of pointer arithmetic for heap-buffer boundary checks. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2016-2177) - An information disclosure vulnerability exists in the OpenSSL component in dsa_sign_setup() function in dsa_ossl.c due to a failure to properly ensure the use of constant-time operations. An unauthenticated, remote attacker can exploit this, via a timing side-channel attack, to disclose DSA key information. (CVE-2016-2178) - A denial of service vulnerability exists in the OpenSSL component in the DTLS implementation due to a failure to properly restrict the lifetime of queue entries associated with unused out-of-order messages. An unauthenticated, remote attacker can exploit this, by maintaining multiple crafted DTLS sessions simultaneously, to exhaust memory. (CVE-2016-2179) - An out-of-bounds read error exists in the OpenSSL component in the X.509 Public Key Infrastructure Time-Stamp Protocol (TSP) implementation.

An unauthenticated, remote attacker can exploit this to more easily predict the PRNG output. (CVE-2012-6702) - Multiple buffer overflow conditions exist within Expat, specifically in the XML_GetBuffer() function in file lib/xmlparse.c, due to improper validation of user-supplied input when handling compressed XML content. An unauthenticated, remote attacker can exploit these to execute arbitrary code. (CVE-2015-1283, CVE-2016-4472) - Multiple buffer overflow conditions exist within the Expat XML parser when handling malformed input documents due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these to cause a denial of service condition or the execution of arbitrary code.
