⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative control, create backdoor accounts, delete legitimate users, and compromise the entire video surveillance system.
Likely Case
Malicious insiders or compromised low-privilege accounts escalate privileges to modify system settings, access restricted video feeds, or disrupt operations.
If Mitigated
With proper network segmentation and monitoring, impact is limited to isolated video management systems without lateral movement to critical infrastructure.
🎯 Exploit Status
Requires authenticated low-privilege access; exploitation details are not publicly documented but referenced in GitHub repository.
