Vulnerability Note VU#909678

DameWare Mini Remote Control vulnerable to buffer overflow via specially crafted packets

Overview

DameWare Mini Remote Control is a lightweight remote control intended primarily for administrators and help desks for management of desktop systems. A vulnerability in DameWare Mini Remote Control may permit an unauthenticated attacker to execute arbitrary code on the system.

I. Description

A buffer overflow vulnerability has been discovered in versions of DameWare Mini Remote Control prior to 3.73. A remote attacker can send a specially crafted packet to the DameWare Mini Remote Control (default port 6129/TCP) to mimic a client and exploit this vulnerability against the server. Since the buffer overflow occurs in a section of the code used to handle authentication, a remote unauthenticated attacker can execute arbitrary code on the system.

The CERT/CC has seen reports of active exploitation.

II. Impact

An unauthenticated attacker can exploit this vulnerability to execute arbitrary code.

III. Solution

This vulnerability is resolved in version 3.73 or higher.

Block access to the DameWare Mini Remote Control Service port (default 6129/TCP) at the network perimeter. This will not mitigate attacks from within the firewall perimeter, but may mitigate attacks from outside your network.
