Summary

Multiple cross-site scripting (XSS) vulnerabilities in blog/index.php in Moodle before 1.8.13 and 1.9.x before 1.9.9 allow remote attackers to inject arbitrary web script or HTML via unspecified parameters.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Embedding Scripts in Non-Script Elements
    This attack is a form of Cross-Site Scripting (XSS) where malicious scripts are embedded in elements that are not expected to host scripts such as image tags (<img>), comments in XML documents (< !-CDATA->), etc. These tags may not be subject to the same input validation, output validation, and other content filtering and checking routines, so this can create an opportunity for an attacker to tunnel through the application's elements and launch a XSS attack through other elements. As with all remote attacks, it is important to differentiate the ability to launch an attack (such as probing an internal network for unpatched servers) and the ability of the remote attacker to collect and interpret the output of said attack.
  • Embedding Scripts within Scripts
    An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts. The attacker leverages this capability to execute scripts to execute his/her own script by embedding it within other scripts that the target software is likely to execute. The attacker must have the ability to inject script into script that is likely to be executed. If this is done, then the attacker can potentially launch a variety of probes and attacks against the web server's local environment, in many cases the so-called DMZ, back end resources the web server can communicate with, and other hosts. With the proliferation of intermediaries, such as Web App Firewalls, network devices, and even printers having JVMs and Web servers, there are many locales where an attacker can inject malicious scripts. Since this attack pattern defines scripts within scripts, there are likely privileges to execute said attack on the host. Of course, these attacks are not solely limited to the server side, client side scripts like Ajax and client side JavaScript can contain malicious scripts as well. In general all that is required is for there to be sufficient privileges to execute a script, but not protected against writing.
  • Cross-Site Scripting in Error Pages
    An attacker distributes a link (or possibly some other query structure) with a request to a third party web server that is malformed and also contains a block of exploit code in order to have the exploit become live code in the resulting error page. When the third party web server receives the crafted request and notes the error it then creates an error message that echoes the malformed message, including the exploit. Doing this converts the exploit portion of the message into to valid language elements that are executed by the viewing browser. When a victim executes the query provided by the attacker the infected error message error message is returned including the exploit code which then runs in the victim's browser. XSS can result in execution of code as well as data leakage (e.g. session cookies can be sent to the attacker). This type of attack is especially dangerous since the exploit appears to come from the third party web server, who the victim may trust and hence be more vulnerable to deception.
  • Cross-Site Scripting Using Alternate Syntax
    The attacker uses alternate forms of keywords or commands that result in the same action as the primary form but which may not be caught by filters. For example, many keywords are processed in a case insensitive manner. If the site's web filtering algorithm does not convert all tags into a consistent case before the comparison with forbidden keywords it is possible to bypass filters (e.g., incomplete black lists) by using an alternate case structure. For example, the "script" tag using the alternate forms of "Script" or "ScRiPt" may bypass filters where "script" is the only form tested. Other variants using different syntax representations are also possible as well as using pollution meta-characters or entities that are eventually ignored by the rendering engine. The attack can result in the execution of otherwise prohibited functionality.

    "Several remote vulnerabilities have been discovered in Moodle, a
    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."
