AI Analysis

Impact

A path traversal flaw in the UniFi Network Application allows an adversary with network access to read arbitrary files on the host and potentially manipulate files to gain access to underlying account credentials.

Affected Systems

The vulnerability affects Ubiquiti Inc's UniFi Network Application. No specific version information is supplied, so all installations should be considered at risk until vendor-disclosed details are available.

Risk and Exploitability

The CVSS score of 10 indicates maximum severity. EPSS data is not available and the vulnerability is not listed in CISA's KEV catalog. The likely attack vector involves crafting HTTP requests to the UniFi controller over the local network to traverse directories and access files outside the intended scope, which could lead to further compromise if privileged accounts are reached.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply any vendor‑provided patch for the UniFi Network Application.
  • If no patch is available, restrict network access to the controller to trusted devices only, for example by applying firewall rules to block untrusted segments.
  • Monitor the Ubiquiti community advisory link for updates on patches or workarounds.
  • Implement network segmentation to isolate the UniFi controller from untrusted segments to reduce exposure.
