Nginx UI vulnerability analysis and mitigation

Overview

Nginx-UI, a web interface for managing Nginx configurations, was found to be vulnerable to an authenticated arbitrary command execution vulnerability through CRLF attack when modifying the values of test_config_cmd or start_cmd parameters. This vulnerability (CVE-2024-23828) was discovered as a result of an incomplete fix for previous vulnerabilities CVE-2024-22197 and CVE-2024-22198. The issue was patched in version 2.0.0.beta.12 (GitHub Advisory).

Technical details

The vulnerability allows authenticated users to inject commands directly into the app.ini configuration file using CRLF (Carriage Return Line Feed) attacks. This injection capability specifically targets the test_config_cmd and start_cmd parameters. The CVSS v3.1 score for this vulnerability is 8.8 HIGH with the vector string AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H (NVD).

Impact

If successfully exploited, this vulnerability enables authenticated attackers to execute arbitrary commands on the host system running the Nginx-UI application. This could lead to complete system compromise within the context of the application's privileges (GitHub Advisory).

Mitigation and workarounds

Users should upgrade to Nginx-UI version 2.0.0.beta.12 or later, which contains the fix for this vulnerability (GitHub Advisory).
