nginx 0.9.x < 1.30.4 / 1.31.x < 1.31.3 Heap-based Buffer Overflow

According to its Sever response header, the installed version of nginx is 0.9.x prior to 1.30.4 or 1.31.x prior to 1.31.3. It is, therefore, affected by the following issue : - A vulnerability exists in NGINX Plus and NGINX Open Source when a map directive uses regex matching and a string...

GHSA-CF23-7QXJ-XMHR Nginx UI: nginx config directive denylist (ValidateConfigFile) is bypassable via same-line ";" separation → authenticated directive injection (RCE on the official image)

Summary config.ValidateConfigFile is the security control that blocks dangerous nginx directives js, perl, loadmodule of njs/perl modules, user root. Its directive scanner is bypassable: it splits the config by newlines and inspects only the FIRST token of each line, but nginx separates directive...

Nginx UI: MCP `nginx_config_add` Bypasses Directive Validation — Authenticated RCE

Summary The MCP tool nginxconfigadd writes nginx configuration files to disk and triggers an nginx reload without calling config.ValidateConfigFile. The identical flow in the REST API POST /api/configs does call that function and correctly rejects dangerous directives. An authenticated attacker c...

Nginx UI: MCP configuration tools bypass restricted directive validation and allow secondary authenticated users to execute NJS in Nginx worker context

Summary The regular HTTP configuration API rejects restricted Nginx directives such as loadmodule, jsimport, and jscontent. However, the MCP configuration interface allows a secondary authenticated user to write and apply equivalent restricted configuration content. In the lab, this allowed the...
