Summary

CRLF injection vulnerability in the drupal_goto function in includes/common.inc Drupal 4.7.x before 4.7.8 and 5.x before 5.3 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unspecified vectors.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Accessing/Intercepting/Modifying HTTP Cookies
    This attack relies on the use of HTTP Cookies to store credentials, state information and other critical data on client systems. The first form of this attack involves accessing HTTP Cookies to mine for potentially sensitive data contained therein. The second form of this attack involves intercepting this data as it is transmitted from client to server. This intercepted information is then used by the attacker to impersonate the remote user/session. The third form is when the cookie's content is modified by the attacker before it is sent back to the server. Here the attacker seeks to convince the target server to operate on this falsified information.
  • HTTP Response Splitting
    This attack uses a maliciously-crafted HTTP request in order to cause a vulnerable web server to respond with an HTTP response stream that will be interpreted by the client as two separate responses instead of one. This is possible when user-controlled input is used unvalidated as part of the response headers. The target software, the client, will interpret the injected header as being a response to a second request, thereby causing the maliciously-crafted contents be displayed and possibly cached. To achieve HTTP Response Splitting on a vulnerable web server, the attacker:
  • Simple Script Injection
    An attacker embeds malicious scripts in content that will be served to web browsers. The goal of the attack is for the target software, the client-side browser, to execute the script with the users' privilege level. An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute code and scripts. Web browsers, for example, have some simple security controls in place, but if a remote attacker is allowed to execute scripts (through injecting them in to user-generated content like bulletin boards) then these controls may be bypassed. Further, these attacks are very difficult for an end user to detect.
  • AJAX Fingerprinting
    This attack utilizes the frequent client-server roundtrips in Ajax conversation to scan a system. While Ajax does not open up new vulnerabilities per se, it does optimize them from an attacker point of view. In many XSS attacks the attacker must get a "hole in one" and successfully exploit the vulnerability on the victim side the first time, once the client is redirected the attacker has many chances to engage in follow on probes, but there is only one first chance. In a widely used web application this is not a major problem because 1 in a 1,000 is good enough in a widely used application. A common first step for an attacker is to footprint the environment to understand what attacks will work. Since footprinting relies on enumeration, the conversational pattern of rapid, multiple requests and responses that are typical in Ajax applications enable an attacker to look for many vulnerabilities, well-known ports, network locations and so on.

    In some circumstances Drupal allows user-supplied data to become part

    response splitting attacks which may lead to a variety of issues,
    among them cache poisoning, cross-user defacement and injection of
    arbitrary code.
    
    The Drupal installer allows any visitor to provide credentials for a
    database when the site's own database is not reachable. This allows
    attackers to run arbitrary code on the site's server. An immediate
    workaround is the removal of the file install.php in the Drupal root
    directory.
    
    The allowed extension list of the core Upload module contains the
    extension HTML by default. Such files can be used to execute arbitrary
    script code in the context of the affected site when a user views the
    file. Revoking upload permissions or removing the .html extension from
    the allowed extension list will stop uploads of malicious files. but
    will do nothing to protect your site againstfiles that are already
    present. Carefully inspect the file system path for any HTML files. We
    recommend you remove any HTML file you did not update yourself. You
    should look for , CSS includes, JavaScript includes, and onerror=''
    attributes if you need to review files individually.
    
    The Drupal Forms API protects against cross site request forgeries
    (CSRF), where a malicious site can cause a user to unintentionally
    submit a form to a site where he is authenticated. The user deletion
    form does not follow the standard Forms API submission model and is
    therefore not protected against this type of attack. A CSRF attack may
    result in the deletion of users.
    
    The publication status of comments is not passed during the
    hook_comments API operation, causing various modules that rely on the
    publication status (such as Organic groups, or Subscriptions) to mail
    out unpublished comments."
