Patch Published: N/A
CVE [?]: CVE-2008-4193
CPE [?]: N/A

Synopsis

The remote web server is affected by a buffer overflow vulnerability.

Description

The remote host is running Alt-N's SecurityGateway for Exchange/SMTP, an email spam firewall for Exchange and SMTP servers.

The version of SecurityGateway installed on the remote host is earlier than 1.0.2. Such versions are reportedly affected by a buffer overflow that can be triggered using a long 'username' parameter to the 'SecurityGateway.dll' script to execute arbitrary code on the remote host with SYSTEM-level privileges, potentially resulting in a complete compromise of the affected host.

Solution

Upgrade to SecurityGateway 1.0.2 or later.
