Phormer Multiple Cross-Site Scripting Vulnerabilities

Thursday, 20 September 2007

Description:
nights.shadow has discovered some vulnerabilities in Phormer, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed to the "u", "p", "c", and "s" parameters in index.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

NOTE: Other parameters may also be affected.

The vulnerabilities are confirmed in version 3.31. Other versions may also be affected.

Solution:
Edit the source code to ensure that input is properly sanitised.
