zj1983 zz, SQL Injection, CVE-2025-1821 (Critical)

Listen to this Post

How CVE-2025-1821 Works

The vulnerability exists in the `getUserOrgForUserId` function within ZorgAction.java, where improper sanitization of the `userID` parameter allows SQL injection. Attackers can craft malicious SQL queries through this parameter, enabling unauthorized database access, data exfiltration, or command execution. The flaw is remotely exploitable without authentication, making it critical. The lack of input validation and prepared statements in the code exposes the application to injection attacks.
