How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-55740, inspect your project dependencies for Github.com/Anipaleja/nginx defender:

inspect dependencies for github.com/Anipaleja/nginx-defender

Analyze the terminal output to locate any version of Github.com/Anipaleja/nginx defender in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.5.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1392: Use of Default Credentials, where the product uses default credentials (such as passwords or cryptographic keys) for potentially critical functionality. In Github.com/Anipaleja/nginx defender, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact This is a configuration vulnerability affecting nginx-defender deployments. Example configuration files [config.yaml](https://github.com/Anipaleja/nginx-defender/blob/main/config.yaml), [docker-compose.yml](https://github.com/Anipaleja/nginx-defender/blob/main/docker-compose.yml) contain default credentials (`default_password: "change_me_please"`, `GF_SECURITY_ADMIN_PASSWORD=admin123`). If users deploy nginx-defender without changing these defaults, attackers with network access could gain administrative control, bypassing security protections. **Who is impacted?** All users who deploy nginx-defender with default credentials and expose the admin interface to untrusted networks. ### Patches The issue is addressed in v1.5.0 and later. Startup warnings are added if default credentials are detected. Documentation now strongly recommends changing all default passwords before deployment. Patched versions: 1.5.0 and later **Will be fully patched in v1.7.0 and later** ### Workarounds Users can remediate the vulnerability without upgrading by manually changing all default credentials in configuration files before deployment: ```yaml # config.yaml auth: default_password: "your_strong_password_here" ``` ```yml # docker-compose.yml - GF_SECURITY_ADMIN_PASSWORD=your_strong_password ``` Restrict access to the admin interface and use environment variables for secrets. ### References - [Security Configuration Guide](https://github.com/Anipaleja/nginx-defender/blob/main/docs/security-config.md) - [Full Security Advisory](https://github.com/Anipaleja/nginx-defender/security/advisories) - [Library README](https://github.com/Anipaleja/nginx-defender/blob/main/lib/README.md) - [README](https://github.com/Anipaleja/nginx-defender/blob/main/README.md)
