NGINX Plus and NGINX Open Source have a vulnerability in the ngx http proxy v2 module and ngx http grpc module modules. This vulnerability exists when the proxy http version to 2 or grpc pass directives are used to proxy HTTP/2 traffic, the ignore invalid headers directive is set to off, and the large client header buffers directive size is larger than 2 megabytes. A remote, unauthenticated attacker, along with conditions beyond their control, could send large headers while creating an upstream request. This may cause a heap-based buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
