Rule name: HTTP Request Smuggling
|
|
Filtering stage: Request phase
|
|
Threat level: Critical
|
|
Rule description: This rule searches for HTTP/WEBDAV method names that combine with the words HTTP/\d or CR/LF characters. This will point to an attempt to inject a second request into the request in order to bypass testing performed on the main request, such as the CVE9-20372 (Nginx<1.17.7 request smuggling vulnerability). reference resources: http://projects.webappsec.org/HTTP-Request-Smuggling
