Detailed Description The relevant host is running a version of Caudium Web Server which is older than 1.4.4. Caudium is the name of a GPL-ed (free for commercial and personal use) web server written in Pike and in C. Caudium Web Server versions prior to 1.4.4 RC2 are vulnerable to a denial of service attack, caused by an off-by-one buffer underflow in the parsing of HTTP requests. A remote attacker could send a specially crafted HTTP request containing a variable of '=&' to cause the affected Web server to crash.

* Note: This check solely relied on the banner of the remote HTTP server to assess this vulnerability, so this might be a False Positive.
