Two vulnerabilities have been reported in WEBInsta Limbo, which can be exploited by malicious people to compromise a vulnerable system.

1) Input passed to the "absolute_path" parameter in "index2.php" is not properly verified, before it is used to include files. This can be exploited to include arbitrary files from external and local resources.

The vulnerability has been confirmed in version 1.0.2. Prior versions may also be affected.

2) Input passed to the "Itemid" parameter in index.php is not properly verified before it is used. This can be exploited to execute arbitrary PHP commands.

Example:
http://[host]/index.php?option=frontpage&Itemid=[code]

The vulnerability has been confirmed in version 1.0.2, 1.0.4.1, and 1.0.4.2 (without the December 2005 patch). Prior versions may also be affected.
