info:
  name: AVTECH IP Camera - Command Injection
  author: DhiyaneshDK
  severity: high
  description: |
    The endpoint `/cgi-bin/supervisor/Factory.cgi` is vulnerable to command injection via the `action` parameter, allowing remote code execution.
  impact: |
    Authenticated attackers can execute arbitrary commands on the AVTECH IP camera system, achieving complete device compromise and potentially using it as a pivot point for network attacks.
  remediation: |
    Apply security patches from AVTECH or implement network segmentation and access controls to restrict access to the vulnerable endpoint.
