HP Power Manager is a web-based application that enables administrators to manage an HP UPS from a browser-based management console.
A stack-based buffer overflow in the HP Power Manager management web server allows remote attackers to execute arbitrary code via the Login variable of the login form.
HP's resolution is to limit access to trusted users.
Exploit works on HP Power Manager 4.2.7. Windows patch KB933729 (rpct4.dll version 5.2.3790.4115) must be installed.
