This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Nginx UI is a web user interface for the Nginx web server. From 2.5.0 until 2.6.0, the node-signature authentication path performs temporary file staging of an attacker-controlled request body and synchronizes it before validating the body digest and cryptographic signature. An unauthenticated remote client that can reach the API and provide syntactically valid signature metadata can consume temporary filesystem capacity, disk input and output, and request-processing resources before rejection. The issue affects availability and does not bypass authentication or provide confidentiality or integrity impact. This issue is fixed in version 2.6.0.

Remediation

Check the references section for vendor advisories and patches from nginxui. Update nginx_ui to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
