Description:
Sonyy has discovered two vulnerabilities in w-Agora, which can be exploited by malicious people to disclose potentially sensitive information.
Input passed to the "bn" parameter in index.php and "file" in modules.php is not properly sanitised before being used to include files. This can be exploited to include arbitrary files from local resources.
Successful exploitation requires that "magic_quotes_gpc" is disabled.
Examples:
http://[host]/[path]/index.php?site=demos&bn=../../../../[file]%00
http://[host]/[path]/modules.php?mod=fm&file=../../../../[file]%00&bn=fm_d1
The vulnerabilities are confirmed in version 4.1.5. Prior versions may also be affected.
Solution:
Update to version 4.1.6.
