CVE-2026-31927: CWE-23 in Anviz Anviz CX7 Firmware
Anviz CX7 Firmware is vulnerable to an authenticated CSV upload which allows path traversal to overwrite arbitrary files (e.g., /etc/shadow), enabling unauthorized SSH access when combined with debug‑setting changes.
AI Analysis
Technical Summary
CVE-2026-31927 describes a path traversal vulnerability in Anviz CX7 Firmware. An authenticated user can upload a crafted CSV file that traverses directories and overwrites arbitrary files on the device filesystem. Overwriting critical files like /etc/shadow can lead to unauthorized SSH access when combined with changes to debug settings. The vulnerability requires authentication and has a medium impact on integrity but no direct confidentiality or availability impact is indicated. No vendor advisory or patch information is currently available.
Potential Impact
The vulnerability allows an authenticated attacker to overwrite arbitrary files on the device, which can lead to unauthorized SSH access if debug settings are altered. This compromises the integrity of the device and could enable further unauthorized control. There is no indication of confidentiality or availability impact from the provided data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict authenticated user access to trusted personnel only and monitor for suspicious activity related to file uploads and SSH access. Avoid enabling debug settings unless necessary and secure them appropriately.
