CWEhttps://cwe.mitre.org/data/definitions/1021.html

Mozilla Firefox before 26.0 and SeaMonkey before 2.23 do not properly consider the sandbox attribute of an IFRAME element during processing of a contained OBJECT element, which allows remote attackers to bypass intended sandbox restrictions via a crafted web site.

Weakness

The web application does not restrict or incorrectly restricts frame objects or UI layers that belong to another application or domain.

Potential Mitigations

  • The use of X-Frame-Options allows developers of web content to restrict the usage of their application within the form of overlays, frames, or iFrames. The developer can indicate from which domains can frame the content.
  • The concept of X-Frame-Options is well documented, but implementation of this protection mechanism is in development to cover gaps. There is a need for allowing frames from multiple domains.
  • A developer can use a “frame-breaker” script in each page that should not be framed. This is very helpful for legacy browsers that do not support X-Frame-Options security feature previously mentioned.
  • It is also important to note that this tactic has been circumvented or bypassed. Improper usage of frames can persist in the web application through nested frames. The “frame-breaking” script does not intuitively account for multiple nested frames that can be presented to the user.
