⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise where attackers gain administrative privileges, access sensitive student/teacher data, modify system configurations, and potentially deploy ransomware or other malware.

🟠

Likely Case

Attackers gain elevated privileges to access confidential student records, modify grades, alter user permissions, and potentially pivot to other systems in the network.

🟢

If Mitigated

Limited impact with proper network segmentation, strong authentication controls, and monitoring that detects privilege escalation attempts.

🌐 Internet-Facing: HIGH - The vulnerability affects web-based software that is typically exposed to the internet for remote access by schools and administrators.
🏢 Internal Only: MEDIUM - While primarily internet-facing, internal attackers could also exploit this if they have network access to the Eskooly instance.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

The vulnerability involves user enumeration via account settings, suggesting relatively straightforward exploitation once initial access is obtained.
