Open Webmail < 2.51 20050430 Shell Escape Arbitrary Command Execution

High

Synopsis

The remote host is vulnerable to an flaw that allows attackers to execute arbitrary commands.

Description

The remote host is running Open Webmail, an open-source perl script that gives remote users a web-based interface to email. This version of Open Webmail is vulnerable to a content-parsing flaw that would allow a remote attack to run arbitrary code on the Open Webmail server. Specifically, the application fails to parse out the '|' character which can be used to append commands to system calls.

Solution

Upgrade to version 2.51 20050430 or higher.
