CVE Vulnerabilities


Cross-Site Request Forgery (CSRF)

CVSS 3.x
CVSS 2.x

Multiple cross-site request forgery (CSRF) vulnerabilities in OpenX 2.8.11 and earlier allow remote attackers to hijack the authentication of administrators for requests that delete (1) users via admin/agency-user-unlink.php, (2) advertisers via admin/advertiser-delete.php, (3) banners via admin/banner-delete.php, (4) campaigns via admin/campaign-delete.php, (5) channels via admin/channel-delete.php, (6) affiliate websites via admin/affiliate-delete.php, or (7) zones via admin/zone-delete.php.


The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request.

Potential Mitigations

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, use anti-CSRF packages such as the OWASP CSRFGuard. [REF-330]
  • Another example is the ESAPI Session Management control, which includes a component for CSRF. [REF-45]
  • Use the “double-submitted cookie” method as described by Felten and Zeller:
  • When a user visits a site, the site should generate a pseudorandom value and set it as a cookie on the user’s machine. The site should require every form submission to include this value as a form value and also as a cookie value. When a POST request is sent to the site, the request should only be considered valid if the form value and the cookie value are the same.
  • Because of the same-origin policy, an attacker cannot read or modify the value stored in the cookie. To successfully submit a form on behalf of the user, the attacker would have to correctly guess the pseudorandom value. If the pseudorandom value is cryptographically strong, this will be prohibitively difficult.
  • This technique requires Javascript, so it may not work for browsers that have Javascript disabled. [REF-331]
