Title: GTCatalog Remote File Include Vulnerability

Severity: MODERATE

Description:

GTCatalog is software designed to maintain a catalog of products. It is implemented in PHP and is available for a variety of platforms including Microsoft Windows and Linux variant operating systems.

GTCatalog is prone to an issue that may allow remote attackers to include files located on attacker-controlled servers.

This vulnerability is as a result of insufficient sanitization performed on remote user supplied data. Specifically the PHP script file 'index.php' is vulnerable to this issue.

Under some circumstances, it is possible for remote attackers to influence the include path for files ending with '.custom.inc' to point to an external file on a remote server by manipulating the '$function' and '$custom' URI parameters.

If the remote file is a malicious file, this may be exploited to execute arbitrary system commands in the context of the web server.

This vulnerability was reported for GTCatalog 0.9.1 and earlier.

Affected Products:

  • GTCatalog GTCatalog 0.8.16
  • GTCatalog GTCatalog 0.9.0
  • GTCatalog GTCatalog 0.9.1
