DESCRIPTION:
Kacper has reported a vulnerability in KGB, which can be exploited by
malicious people to compromise a vulnerable system.
Input passed to the "skinnn" parameter in kgbmod/sesskglogadmin.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 or to execute arbitrary PHP code by
including kg/wpisy.txt, which contains guestbook entries.
Successful exploitation requires that "register_globals" is enabled
and "magic_quotes_gpc" is disabled.
The vulnerability is reported in version 1.9. Other versions may also
be affected.
SOLUTION:
Edit the source code to ensure that input is properly verified.
