## Technical details

The vulnerability is a mass assignment improper input validation flaw in the HrInfoController.updateHr() endpoint (PUT /hr/info). The endpoint accepts JSON input and binds it directly to the Hr object without validating ownership or filtering sensitive fields; an attacker can specify an arbitrary user ID and set the password field to a self-generated BCrypt hash. The HrMapper.xml updates the password when present, enabling a low-privilege user to reset admin credentials. Attack requires low-privilege user authentication (e.g., libai/123) and network access to the PUT /hr/info endpoint; no further user interaction is needed. An attacker gains vertical privilege escalation to ROLE_admin and complete system control. The vendor has been contacted but provided no response or patch.
