⚠️ Risk & Real-World Impact
Worst Case
Attacker steals administrator session cookies, gains full system access, and potentially compromises the entire HR database including sensitive employee information.
Likely Case
Attacker steals user session cookies to impersonate legitimate users, accesses sensitive HR data, or performs unauthorized actions within the application.
If Mitigated
With proper Content Security Policy (CSP) headers and input validation, impact is limited to temporary session compromise for individual users.
🎯 Exploit Status
Exploitation requires user interaction (clicking malicious link) but is trivial to weaponize in phishing campaigns.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Check GitHub repository for updates
2. Apply proper output encoding for the 'next' parameter
3. Implement Content Security Policy headers
4. Validate and sanitize all user inputs
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rule
allBlock requests containing malicious scripts in the 'next' parameter
WAF-specific configuration required
Content Security Policy Implementation
allAdd CSP headers to restrict script execution
Content-Security-Policy: script-src 'self'
🧯 If You Can't Patch
- Implement strict Content Security Policy headers to prevent script execution
- Deploy web application firewall with XSS detection rules
🔍 How to Verify
Check if Vulnerable:
Test by accessing: /login?next=javascript:alert('XSS') and check if script executesCheck Version:
Check IceHRM version in admin panel or application footerVerify Fix Applied:
Verify the 'next' parameter is properly URL-encoded and scripts do not execute📡 Detection & Monitoring
Log Indicators:
- Unusual 'next' parameter values in login requests
- Multiple failed login attempts with suspicious parameters
Network Indicators:
