Summary

Moodle 1.8.x and 1.9.x before 1.9.8 does not enable the "Regenerate session id during login" setting by default, which makes it easier for remote attackers to conduct session fixation attacks.

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.

    course management system. The Common Vulnerabilities and Exposures
    project identifies the following problems :
    
      - CVE-2010-1613
        Moodle does not enable the 'Regenerate session id during
        login' setting by default, which makes it easier for
        remote attackers to conduct session fixation attacks.
    
      - CVE-2010-1614
        Multiple cross-site scripting (XSS) vulnerabilities
        allow remote attackers to inject arbitrary web script or
        HTML via vectors related to (1) the Login-As feature or
        (2) when the global search feature is enabled,
        unspecified global search forms in the Global Search
        Engine.
    
      - CVE-2010-1615
        Multiple SQL injection vulnerabilities allow remote
        attackers to execute arbitrary SQL commands via vectors
        related to (1) the add_to_log function in
        mod/wiki/view.php in the wiki module, or (2) 'data
        validation in some forms elements' related to
        lib/form/selectgroups.php.
    
      - CVE-2010-1616
        Moodle can create new roles when restoring a course,
        which allows teachers to create new accounts even if
        they do not have the moodle/user:create capability.
    
      - CVE-2010-1617
        user/view.php does not properly check a role, which
        allows remote authenticated users to obtain the full
        names of other users via the course profile page.
    
      - CVE-2010-1618
        A Cross-site scripting (XSS) vulnerability in the phpCAS
        client library allows remote attackers to inject
        arbitrary web script or HTML via a crafted URL, which is
        not properly handled in an error message.
    
      - CVE-2010-1619
        A Cross-site scripting (XSS) vulnerability in the
        fix_non_standard_entities function in the KSES HTML text
        cleaning library (weblib.php) allows remote attackers to
        inject arbitrary web script or HTML via crafted HTML
        entities.
    
      - CVE-2010-2228
        A Cross-site scripting (XSS) vulnerability in the MNET
        access-control interface allows remote attackers to
        inject arbitrary web script or HTML via vectors
        involving extended characters in a username.
    
      - CVE-2010-2229
        Multiple cross-site scripting (XSS) vulnerabilities in
        blog/index.php allow remote attackers to inject
        arbitrary web script or HTML via unspecified parameters.
    
      - CVE-2010-2230
        The KSES text cleaning filter in lib/weblib.php does not
        properly handle vbscript URIs, which allows remote
        authenticated users to conduct cross-site scripting
        (XSS) attacks via HTML input.
    
      - CVE-2010-2231
        A Cross-site request forgery (CSRF) vulnerability in
        report/overview/report.php in the quiz module allows
        remote attackers to hijack the authentication of
        arbitrary users for requests that delete quiz attempts
        via the attemptid parameter."
