Two vulnerabilities have been reported in 4images, which can be exploited by malicious people to disclose sensitive information and by malicious users to conduct script insertion attacks.
1) Input passed to the "user_homepage" parameter in member.php is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when a posted comment is viewed.
2) Input passed via the "l" parameter to global.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local resources via directory traversal attacks and URL-encoded NULL bytes.
Successful exploitation requires that "magic_quotes_gpc" is disabled.
The vulnerabilities are reported in versions prior to 1.7.7.
