## Description

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.
