Administrator credential disclosure via manipulated search parameters

Published Aug 20, 2026 · Updated Aug 21, 2026

SQL injection in the CWP User Finder in Genians Genian NAC and Genian ZTNA allows remote attackers to obtain administrator credentials. The user-search page accepts attacker-controlled URL parameters and uses them to query the user table without authentication, returning stored administrator credentials. Reachability requires network access to the CWP User Finder, but no account or user interaction; the published impact is credential disclosure only.
