medium Tenable Cloud Security Plugin ID 435009

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - nginx-defender is a high-performance, enterprise-grade Web Application Firewall (WAF) and threat detection
 system engineered for modern web infrastructure. This is a configuration vulnerability affecting nginx-
 defender deployments. Example configuration files config.yaml and 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. The issue is addressed in v1.5.0 and later. (CVE-2025-55740)
