• → Monitor for breakpoints or runtime tampering of the DataHandle class methods UserEntityPrivs, UserFieldPrivs, and UserReportPrivs inside Perspective.data.dll — these are the exact interception points used to escalate privileges. ↗

• · The privilege escalation occurs entirely client-side after authentication; the server performs no cross-validation of permission values set by the thick client, meaning server-side logs may show no anomaly during the attack. ↗
• · The exploit requires the attacker to already be an authenticated (but unprivileged) user; it is not an unauthenticated attack vector. ↗
• · One privilege action remains blocked even after exploitation: creating a new user account is not possible via this technique. ↗
