Summary
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. 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.
Important: This vulnerability in NGINX's `ngx_http_slice_module` could lead to memory disclosure or denial of service. The impact on Red Hat products is reduced because the `ngx_http_slice_module` is not enabled by default.
Exploitation requires explicit configuration of the module with the `slice` directive and unnamed regex captures, or during a background cache update, limiting exposure in typical deployments. Red Hat severity: Important — CVSS 8.2 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H).
Weakness: CWE-824.

Mitigation checklist
- To mitigate this issue, disable the ngx_http_slice_module entirely if it is not required. If the module must be used, avoid unnamed regex captures with the slice directive and explicitly disable proxy_cache_background_update. Reload or restart the NGINX service to apply these changes. Please note this may cause a brief service interruption.
