Description:
rgod has reported two vulnerabilities in Xoops, which can be exploited by malicious people to disclose sensitive information and potentially compromise a vulnerable system.
Input passed to the "xoopsConfig" array parameter when the "xoopsOption[nocommon]" parameter is defined isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from local resources.
Examples:
http://[host]/misc.php?xoopsOption[nocommon]=1&xoopsConfig[language]=[file]%00
http://[host]/index.php?xoopsOption[nocommon]=1&xoopsConfig[theme_set]=[file]%00
Successful exploitation requires that "register_globals" is enabled and that "magic_quotes_gpc" is disabled.
This can further be exploited to include PHP code injected into Apache web logs or include PHP code injected into uploaded avatar images (requires that avatar upload support is enabled and knowledge of the uploaded filename).
The vulnerabilities have been reported in version 2.0.13.2 and prior.
Solution:
Apply patch.
