HTTP: Malicious Host Header

This signature detects attempts to exploit a known vulnerability in the host header field of Multiple Web Servers. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the server.

Extended Description

The Novell eDirectory server iMonitor is prone to a stack-based buffer-overflow vulnerability because it fails to perform sufficient bounds checking on client-supplied data before copying it to a buffer. An attacker could leverage this issue to execute arbitrary code with administrative privileges. A successful exploit could result in the complete compromise of the affected system.
