Multiple Plugins from the CatchThemes vendor do not perform capability and CSRF checks in the ctp_switch AJAX action, which could allow any authenticated users, such as Subscriber to change the Essential Widgets WordPress plugin before 1.9, To Top WordPress plugin before 2.3, Header Enhancement WordPress plugin before 1.5, Generate Child Theme WordPress plugin before 1.6, Essential Content Types WordPress plugin before 1.9, Catch Web Tools WordPress plugin before 2.7, Catch Under Construction WordPress plugin before 1.4, Catch Themes Demo Import WordPress plugin before 1.6, Catch Sticky Menu WordPress plugin before 1.7, Catch Scroll Progress Bar WordPress plugin before 1.6, Social Gallery and Widget WordPress plugin before 2.3, Catch Infinite Scroll WordPress plugin before 1.9, Catch Import Export WordPress plugin before 1.9, Catch Gallery WordPress plugin before 1.7, Catch Duplicate Switcher WordPress plugin before 1.6, Catch Breadcrumb WordPress plugin before 1.7, Catch IDs WordPress plugin before 2.4s configurations.

Weakness

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]
