Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Authentication Abuse
    An attacker obtains unauthorized access to an application, service or device either through knowledge of the inherent weaknesses of an authentication mechanism, or by exploiting a flaw in the authentication scheme's implementation. In such an attack an authentication mechanism is functioning but a carefully controlled sequence of events causes the mechanism to grant access to the attacker. This attack may exploit assumptions made by the target's authentication procedures, such as assumptions regarding trust relationships or assumptions regarding the generation of secret values. This attack differs from Authentication Bypass attacks in that Authentication Abuse allows the attacker to be certified as a valid user through illegitimate means, while Authentication Bypass allows the user to access protected material without ever being certified as an authenticated user. This attack does not rely on prior sessions established by successfully authenticating users, as relied upon for the "Exploitation of Session Variables, Resource IDs and other Trusted Credentials" attack patterns.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Utilizing REST's Trust in the System Resource to Register Man in the Middle
    This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to place man in the middle once SSL is terminated. Rest applications premise is that they leverage existing infrastructure to deliver web services functionality. An example of this is a Rest application that uses HTTP Get methods and receives a HTTP response with an XML document. These Rest style web services are deployed on existing infrastructure such as Apache and IIS web servers with no SOAP stack required. Unfortunately from a security standpoint, there frequently is no interoperable identity security mechanism deployed, so Rest developers often fall back to SSL to deliver security. In large data centers, SSL is typically terminated at the edge of the network - at the firewall, load balancer, or router. Once the SSL is terminated the HTTP request is in the clear (unless developers have hashed or encrypted the values, but this is rare). The attacker can utilize a sniffer such as Wireshark to snapshot the credentials, such as username and password that are passed in the clear once SSL is terminated. Once the attacker gathers these credentials, they can submit requests to the web service provider just as authorized user do. There is not typically an authentication on the client side, beyond what is passed in the request itself so once this is compromised, then this is generally sufficient to compromise the service's authentication scheme.
  • Man in the Middle Attack
    This type of attack targets the communication between two components (typically client and server). The attacker places himself in the communication channel between the two components. Whenever one component attempts to communicate with the other (data flow, authentication challenges, etc.), the data first goes to the attacker, who has the opportunity to observe or alter it, and it is then passed on to the other component as if it was never intercepted. This interposition is transparent leaving the two compromised components unaware of the potential corruption or leakage of their communications. The potential for Man-in-the-Middle attacks yields an implicit lack of trust in communication or identify between two components.

    handling a large number of POKE requests (CVE-2008-3263), when handling

    correctly handle SIP INVITE messages that lack a 'From' header
    (CVE-2008-2119), and responds differently to a failed login attempt
    depending on whether the user account exists (CVE-2008-3903,
    CVE-2009-0041).
  
Impact :

    Remote unauthenticated attackers could send specially crafted data to
    Asterisk, possibly resulting in a Denial of Service via a daemon crash,
    call-number exhaustion, CPU or traffic consumption. Remote
    unauthenticated attackers could furthermore enumerate valid usernames
    to facilitate brute-force login attempts.

descriptionBUGTRAQ ID: 30350 CVE(CAN) ID: CVE-2008-3264 Asterisk是开放源码的软件PBX，支持各种VoIP协议和设备。 远程用户可以向Asterisk服务器请求发送部分的固件镜像，但固件下载协议没有初始化握手，可能伪造源地址。此外，对固件文件的IAX2 FWDOWNL请求可能仅为40字节，但生成1040字节的响应。如果向多个不同的Asterisk服务器提交了请求的话，就可以用大量固件报文对用户站点执行flood攻击。 Asterisk Asterisk 1.4.x Asterisk Asterisk 1.2.x Asterisk Asterisk 1.0.x Asterisk Business Edition C.x.x Asterisk Business Edition B.x.x Asterisk Business Edition A.x.x Asterisk AsteriskNOW Asterisk Appliance Developer Kit 0.x.x Asterisk s800i 1.0.x 临时解决方法： * 从目录删除固件镜像并重启Asterisk服务器。 厂商补丁： Asterisk -------- 目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载： <a href=http://www.asterisk.org/ target=_blank>http://www.asterisk.org/</a>
