Vulnerability Note VU#137024

Compaq web-enabled management software contains buffer overflow in authentication username

Overview

The Compaq web-enabled management software contains a buffer overflow in the authentication component of the product. Remote intruders may be able to execute arbitrary code with privileges on affected systems. Many Compaq products are affected, from personal computers to commercial UNIX operating systems.

I. Description

The Compaq web-enabled management software allows system management information to be accessed through a web interface. This web interface is secured by an login dialog accessible on port 2301 of the system running the vulnerable software. The authentication code has a buffer overflow in the username field, allowing a remote intruder to execute arbitrary code with the privileges of the Compaq web-enabled management software. This often includes elevated privileges (e.g., root or Administrator).

Affected Compaq products include those running Microsoft Windows 9x, Windows NT, Windows 2000, NetWare, SCO Open Server, SCO UnixWare 7, RedHat 6.2, RedHat 7.0, Tru64Unix, and OpenVMS. Web-enabled management software is also supported for Compaq storage products.

Compaq has produced a security advisory describing this problem at

II. Impact

A remote intruder may be able to execute arbitrary code with privileges on systems running the vulnerable software.

III. Solution

Block Ports 2301 and 280 at Your Perimeter

Port 2301 (the device management port) is the port used to access the vulnerable code. Blocking access to this port from untrusted sources may reduce the risk of exploitation. You may also wish to block port 280 (the Compaq Insight Manager XE port).
