HTTP: Binary Data in HTTP-Header
This signature detects binary client-to-server data on an HTTP connection. Normally, HTTP connections should not permit binary data (except for file uploads that can be blocked). However, Web servers using characters outside the ASCII character set and Web e-mail systems can send and receive binary data. Administrators should evaluate their networks accordingly.
Extended Description
The presence of binary data in an HTTP request may indicate an attempt to exploit a vulnerability in an HTTP server and launch an attack.
