ArGoSoft Mail Server MLSRVX.DLL Arbitrary File Overwrite Vulnerability

ArGoSoft Mail Server is prone to a vulnerability that lets attackers overwrite arbitrary files.

An attacker can exploit this issue to overwrite arbitrary files on the victim's computer in the context of the vulnerable application using the ActiveX control (typically Internet Explorer). Successful exploits will allow the attacker to cause denial-of-service conditions; other consequences are possible.

ArGoSoft Mail Server 1.8.9.1 is vulnerable; other versions may also be affected.
