HTTP: Invalid Value in Header Field
This protocol anomaly triggers when it detects an HTTP header field with an invalid value, such as a negative content length. This can be an exploit attempt.
Extended Description
A negative Content-Length value in an HTTP request or response should be considered a protocol anomaly. The impact of the protocol anomaly depends on how the web server processes a malformed HTTP message.
