CVE-2022-30231Network attack vector

Authenticated password-hash disclosure via web request

Published Jun 14, 2022 · Updated Nov 12, 2025

Information disclosure in Siemens SICAM GridEdge (Classic) before V2.6.6 allows remote authenticated users to retrieve other users' password hashes. The web server returns password hashes for other user accounts when an authenticated request is made, exposing credential material. Access requires an authenticated account and network reachability; the disclosed hashes can support offline password guessing but do not themselves alter or interrupt the gateway.
