Vulnerability Note VU#170905

DameWare Mini Remote Control vulnerable to buffer overflow via specially crafted authentication requests

A buffer overflow vulnerability has been discovered in versions of DameWare Mini Remote Control prior to 4.9.0. 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. Since the buffer overflow occurs in a section of the code used to handle authentication, a remote unauthenticated attacker can execute arbitrary code on a system.

The CERT/CC has seen reports of active exploitation of a similar vulnerability, CERT VU#909678.

II. Impact

This issue is addressed in version 4.9.0 (alternate link).

Workarounds and mitigation
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.
