Frame Injection Vulnerabilities

Frame injection vulnerabilities, although some people might consider them the same as HTML injection/XSS or even a subset, they really are not the same. Here is why:

  • there is no need to inject special control characters such as angle brackets (unlike HTMLi/XSS)
  • HTMLi/XSS filtering routines will not project against frame injection since the attacker only needs to insert a URL in the non-sanitized parameter
Proof of concept (tested on 10th Oct 2008):
