NGINX Plus and NGINX Open Source have a vulnerability in the ngx http slice module module. When the slice directive and unnamed regex captures are configured or when a background cache update happens, unauthenticated attackers can send requests that may cause uninitialized memory access in the NGINX worker process, leading to limited disclosure of memory or a restart.
Impact:
This vulnerability may allow remote, unauthenticated attackers to have limited control to disclose memory contents or restart the NGINX worker process. There is no control plane exposure; this is a data plane issue only.
Note: The ngx http slice module module is not enabled by default; it's enabled with the --with-http slice module configuration parameter.
Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
