DOS vulnerability for Quoted Quality CSV headers

Impact When Jetty handles a request containing request headers with a large number of “quality” i.e. q parameters such as what are seen on the Accept, Accept-Encoding, and Accept-Language request headers, the server may enter a denial of service DoS state due to high CPU usage while sorting the...

Denial Of Service(DoS)

Jetty is vulnerable to denial of service DoS. The use of multiple Accept headers with a large number of quality causes a high CPU usage, resulting in long durations of CPU processing and crashing of the application...

Ruby on Rails: Regex Injection from request header (Rack::Sendfile, send_file)

I have confirmed that Rack::Sendfile and the Rails sendfile that handles it have a problem handling custom headers for request. It is expected that the X-Sendfile-type and X-Accel-Mapping headers will be sent from nginx, but these headers can also be sent from a user agent such as a browser. This...
