Detailsinfo

A vulnerability was found in 0xJacky Nginx UI up to 2.4.x. It has been declared as problematic. Affected by this vulnerability is an unknown function of the file app.ini of the component Restore Flow. The manipulation with an unknown input leads to a privileges management vulnerability. The CWE definition for the vulnerability is CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Nginx UI is a web user interface for the Nginx web server. From 2.3.8 until 2.5.0, an authenticated administrator with an active secure session can submit attacker-controlled portable backup key material and a matching manifest to POST /api/restore. The restore flow trusts the supplied key, decrypts attacker-controlled contents, and replaces the live app.ini, including protected nginx command settings such as TestConfigCmd. Triggering POST /api/nginx/test then executes the restored command in the Nginx UI runtime context, affecting confidentiality, integrity, and availability. This issue is fixed in version 2.5.0.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-107806 since 10/08/2026. The exploitation appears to be easy. The attack can be launched remotely.
