File Browser through 2.63.23 applies path rules to the requested lexical path but resolves symbolic links without reapplying rules to the target, allowing authenticated users to bypass deny rules. Attackers can read and overwrite rule-denied files by accessing them through in-scope symbolic link aliases that resolve to denied paths.

Why it matters

Internet-facing
Not identified as a common internet-facing category
Exploitation likelihood
medium
  • Remotely exploitable over the network — no physical or local access required
  • High attack complexity — exploitation requires specific conditions
  • Requires low-privilege access first
  • No user interaction needed — can be exploited automatically
Recommended mitigation

Apply the vendor patch as soon as it's available or already released. Review and restrict accounts with the privilege level this vulnerability requires.

This analysis is generated from structured CVSS vector data, CISA KEV cross-referencing, and vendor/product category rules — not a manual expert review. Treat it as a starting point, not a substitute for your own assessment.
