Deeper analysis
Cellinx NVT version 1.0.6.002b contains a path traversal vulnerability (CWE-22) in the /cgi-bin/GetFileContent.cgi component that permits disclosure of arbitrary local files. The flaw received a CVSS 3.1 score of 7.5, reflecting network attack vector, low complexity, and no required authentication or user interaction, with the primary impact limited to high confidentiality loss.
Unauthenticated remote attackers can send crafted requests to the CGI endpoint to retrieve sensitive files from the underlying system. Successful exploitation grants read access to configuration data, credentials, or other restricted content without any prior privileges on the device.
Public references consist of GitHub repositories documenting the issue, but no vendor advisory, patch, or official mitigation guidance is referenced. The EPSS score rose from lower values to a peak of 0.6202 on 2025-12-11 before receding to the current 0.3039, indicating a clear post-disclosure increase in observed exploitation interest.
