💻 Affected Systems
- Serosoft Solutions Pvt Ltd Academia Student Information System (SIS) EagleR
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise where attackers create admin accounts, modify existing users, exfiltrate sensitive student data, and deploy ransomware or other malware.
Likely Case
Attackers create backdoor admin accounts to maintain persistent access, modify user permissions, and potentially access sensitive student and financial information.
If Mitigated
With proper network segmentation and API gateway controls, impact limited to isolated application layer with no lateral movement.
🎯 Exploit Status
The GitHub reference shows detailed research and likely includes exploit code. The simple REST endpoint with no authentication makes exploitation trivial.

🔧 Temporary Workarounds
Block Vulnerable Endpoint
allUse web application firewall or reverse proxy to block access to /rest/staffResource/findAllUsersAcrossOrg
# Example nginx location block:
location /rest/staffResource/findAllUsersAcrossOrg { deny all; }
# Example Apache .htaccess:
<Location "/rest/staffResource/findAllUsersAcrossOrg">
Order deny,allow
Deny from all
</Location>
Implement API Authentication
allAdd authentication middleware to all REST endpoints
# Application-specific implementation required
🧯 If You Can't Patch
- Isolate the SIS application in a separate network segment with strict firewall rules
- Implement comprehensive logging and monitoring for all user creation/modification activities
🔍 How to Verify
Check if Vulnerable:
Attempt to access https://[target]/rest/staffResource/findAllUsersAcrossOrg without authentication. If it returns user data or allows operations, the system is vulnerable.Check Version:
Check application version in admin panel or via /version endpoint if availableVerify Fix Applied:
Test the endpoint with unauthenticated requests - should return 403/401 error or no user data. Verify proper authentication is required for all user management operations.📡 Detection & Monitoring
Log Indicators:
- Unusual user creation events
- Multiple failed authentication attempts followed by successful user creation
- Admin account creation from unusual IP addresses
Network Indicators:
- HTTP POST requests to /rest/staffResource/findAllUsersAcrossOrg without authentication headers
- Unusual traffic patterns to user management endpoints
SIEM Query:
source="web_server" AND (uri="/rest/staffResource/findAllUsersAcrossOrg" OR event="user_created") AND NOT user_agent="monitoring_tool"
