Threats affecting pkg:github/nginx-proxy-manager

Nginx Proxy Manager versions up to 2.16.0 contain an authorization flaw that allows non-administrator users with manage permissions to inject arbitrary nginx directives via the advanced_config field. This improper restriction can enable attackers to manipulate nginx configurations, such as serving arbitrary files or controlling routing for their assigned hosts.

Nginx Proxy Manager versions up to 2.16.0 have a critical vulnerability due to lack of rate-limiting on authentication endpoints. This allows unauthenticated attackers to perform unlimited password guessing attacks and brute-force two-factor authentication codes, potentially gaining full administrative access.

Nginx Proxy Manager versions 2.9.14 through 2.15.1, fixed in commit a5db5ed, contain an authenticated remote code execution vulnerability via OS command injection in the setupCertbotPlugins() function in backend/setup.js, allowing attackers with certificates:manage permission to execute arbitrary commands by storing a malicious payload in the dns_provider_credentials field. The user-controlled dns_provider_credentials value is interpolated directly into a shell command executed via child_process.exec() without sanitization or escaping, causing the injected command to execute upon backend restart.
