HTTP: BadBlue Invalid GET Denial of Service
This signature detects attempts to exploit a known vulnerability against Working Resources BadBlue Web server. Attackers can send a maliciously crafted HTTP GET request to the Web server to disable the daemon and render it unusable until restarted.
Extended Description
Working Resources BadBlue is reportedly prone to a denial of service condition when handling malformed GET requests. It has been discovered that BadBlue does not properly handle requests that do not adhere to RFC standards. When a user connects to BadBlue via the listening port, and issues a "GET HTTP/1.0" request without specifying a document, BadBlue becomes unstable. In most cases, the process will crash.
