Details

NGINX Plus and NGINX Open Source have a vulnerability in the ngxhttpsslmodule module when the sslverifyclient directive is set to "on" or "optional," and the sslocsp directive is set to "on" or the leaf parameters are configured with a resolver. With this configuration, an unauthenticated attacker can send requests along with conditions beyond its control that may cause a heap-use-after-free error in the NGINX worker process. This vulnerability may result in limited modification of data or the NGINX worker process restarting.

 Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
