Vulnerability Information

Severity: High
Vulnerability Published: N/A
Patch Published: N/A
CVE [?]: CVE-2008-0506
CPE [?]: N/A

Synopsis

The remote web server contains a PHP script that allows arbitrary command execution.

Description

The version of Coppermine Photo Gallery installed on the remote host fails to sanitize user input to the 'quality', 'angle' and 'clipval' parameters of the 'picEditor.php' script before using it in 'exec()' statements to call ImageMagick to process new images. An unauthenticated, remote attacker can leverage this issue to execute arbitrary code on the remote host subject to the privileges of the web server user id.

Solution

Either reconfigure the application to use GD as its graphics library, which is the default, or upgrade to Coppermine Photo Gallery version 1.4.15 or later.
