Description

AN HTTPD Server contains a flaw that may allow a remote attacker to inject arbitrary text into the server log. The issue is due to the server not properly sanitizing the CR and LF characters of the URI being processed. Using a specially crafted URI, an attacker can cause the injection of custom lines into the log. This could be used to inject fake browsing entries, or arbitrary commands which can be executed through the cmdIS.DLL module.
