Summary

Session fixation vulnerability in the authentication library in TYPO3 4.0.0 through 4.0.9, 4.1.0 through 4.1.7, and 4.2.0 through 4.2.3 allows remote attackers to hijack web sessions via unspecified vectors related to (1) frontend and (2) backend authentication.

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.

    Some vulnerabilities have been reported in Typo3, which can be
    exploited by malicious people to bypass certain security restrictions,
    conduct cross-site scripting and session fixation attacks, and
    compromise a vulnerable system.
    
    The 'Install tool' system extension uses insufficiently random entropy
    sources to generate an encryption key, resulting in weak security.
    
    The authentication library does not properly invalidate supplied
    session tokens, which can be exploited to hijack a user's session.
    
    Certain unspecified input passed to the 'Indexed Search Engine' system
    extension is not properly sanitised before being used to invoke
    commands. This can be exploited to inject and execute arbitrary shell
    commands.
    
    Input passed via the name and content of files to the 'Indexed Search
    Engine' system extension is not properly sanitised before being
    returned to the user. This can be exploited to execute arbitrary HTML
    and script code in a user's browser session in context of an affected
    site.
    
    Certain unspecified input passed to the Workspace module is not
    properly sanitised before being returned to the user. This can be
    exploited to execute arbitrary HTML and script code in a user's
    browser session in context of an affected site.
    
    Note: It is also reported that certain unspecified input passed to
    test scripts of the 'ADOdb' system extension is not properly sanitised
    before being returned to the user. This can be exploited to execute
    arbitrary HTML and script code in a user's browser session in context
