Description Patrick Del Bello 2024-04-22 13:12:56 UTC 
There exists a security vulnerability in Undertow that can cause remote DoS attacks. Servlets using method that calls HttpServletRequestImpl.getParameterNames() will cause OutOfMemoryError when the client sends a request with huge parameter names. This vulnerability can be exploited by unauthorized users to cause remote denial-of-service (DoS) attack.
