Some vulnerabilities have been reported in Orca Interactive Forum Script, which can be exploited by malicious users to conduct script insertion attacks and malicious people to compromise a vulnerable system.

1) Input passed to the "gConf[dir][layouts]" parameter in layout/default/params.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local or external resources.

Successful exploitation requires that "register_globals" is enabled.

2) Input passed to the "topic_subject" parameter when posting a new topic is not properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious topic is viewed.

The vulnerabilities are confirmed in version 2.0.2. Other versions may also be affected.

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