DESCRIPTION:
Some vulnerabilities have been discovered in log1 CMS, which can be
exploited by malicious people to bypass certain security restrictions
and compromise a vulnerable system.

1) A vulnerability is caused due to admin/main.php not terminating
after sending a HTTP "Location:" header. This can be exploited to
access administrative functions and e.g. conduct script insertion
attacks or upload files.

2) An error in the verification of file uploads can be exploited to
upload files with arbitrary extensions to "db/uploaded/" and e.g
execute arbitrary PHP code.

Successful exploitation requires authentication, but can be exploited
in combination with vulnerability #1.

The vulnerabilities are confirmed in version 2.0. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that proper authentication is
performed. Grant only trusted users access to the application.
