CVE-2020-37093Public exploitNetwork attack vector

WiFi password disclosure via unauthenticated CGI response

Published Feb 3, 2026 · Updated Feb 3, 2026

Information disclosure in Netis E1+ 1.2.32533 and 1.2.32553 allows remote attackers to retrieve WiFi passwords via netcore_get.cgi. The unauthenticated CGI handler returns repeater configuration fields, including SSIDs and plain-text access-point and client passwords, to a GET request. Network reachability to the device web interface is sufficient; no credentials or user interaction are required, and the disclosed passwords enable access to configured wireless networks.
