Descriptions

A vulnerability was found in the resteasy-netty4 library arising from improper handling of HTTP requests using smuggling techniques. When an HTTP smuggling request with an ASCII control character is sent, it causes the Netty HttpObjectDecoder to transition into a BAD_MESSAGE state. As a result, any subsequent legitimate requests on the same connection are ignored, leading to client timeouts, which may impact systems using load balancers and expose them to risk.

Nikos Papadopoulos discovered that RESTEasy improperly handled URL encoding when certain errors occur. An attacker could possibly use this issue to modify the app's behavior for other users through the network. Mirko Selber discovered that RESTEasy improperly validated user input during HTTP response construction. This issue could possibly allow an attacker to cause a denial of service or execute arbitrary code.
