Summary

Drupal 6.x before 6.13 does not prevent users from modifying user signatures after the associated comment format has been changed to an administrator-controlled input format, which allows remote authenticated users to inject arbitrary web script, HTML, and possibly PHP code via a crafted user signature.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Manipulating User-Controlled Variables
    This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An attacker can override environment variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the attacker can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.

The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2009-2372 Gerhard Killesreiter discovered a flaw in the way user signatures are handled. It is possible for a user to inject arbitrary code via a crafted user signature. (SA-CORE-2009-007) - CVE-2009-2373 Mark Piper, Sven Herrmann and Brandon Knight discovered a cross-site scripting issue in the forum module, which could be exploited via the tid parameter. (SA-CORE-2009-007) - CVE-2009-2374 Sumit Datta discovered that certain drupal6 pages leak sensitive information such as user credentials. (SA-CORE-2009-007) Several design flaws in the OpenID module have been fixed, which could lead to cross-site request forgeries or privilege escalations. Also, the file upload function does not process all extensions properly leading to the possible execution of arbitrary code. (SA-CORE-2009-008) The oldstable distribution (etch) does not contain drupal6.

    HTML and script code into forum pages. Such a cross-site scripting

    Wikipedia has more information about cross-site scripting (XSS).
    
    User signatures have no separate input format, they use the format of
    the comment with which they are displayed. A user will no longer be
    able to edit a comment when an administrator changes the comment's
    input format to a format that is not accessible to the user. However
    they will still be able to modify their signature, which will then be
    processed by the new input format.
    
    If the new format is very permissive, via their signature, the user
    may be able to insert arbitrary HTML and script code into pages or,
    when the PHP filter is enabled for the new format, execute PHP code.
    This issue affects Drupal 6.x only.
    
    When an anonymous user fails to login due to mistyping his username or
    password, and the page he is on contains a sortable table, the
    (incorrect) username and password are included in links on the table.
    If the user visits these links the password may then be leaked to
    external sites via the HTTP referer.
    
    In addition, if the anonymous user is enticed to visit the site via a
    specially crafted URL while the Drupal page cache is enabled, a
    malicious user might be able to retrieve the (incorrect) username and
    password from the page cache."
