Answer by Answer
⚠️ Risk & Real-World Impact
Worst Case
Attackers maintain persistent access to compromised user accounts for months or years, enabling data theft, privilege escalation, and lateral movement within the system.
Likely Case
Compromised accounts remain accessible to attackers beyond intended password rotation periods, increasing the window for credential misuse and unauthorized access.
If Mitigated
With proper password policies and monitoring, impact is limited to temporary access until next password change cycle.
🎯 Exploit Status
Exploitation requires initial account compromise through other means, then the vulnerability allows maintaining that access.
