CVE-2026-0408

Credential disclosure via webproc path traversal

Published Jan 13, 2026 · Updated Jan 13, 2026

Path traversal in NETGEAR EX2800, EX3110, EX5000, and EX6110 before 1.0.1.82 allows remote authenticated users to read GUI credentials. The web interface permits traversal to the dynamically generated webproc file, exposing the username and password recorded when submitted to the router GUI. LAN authentication and access to the extender's management IP are required, and exposure is limited to credentials present in that generated file.
