- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers gather detailed system information to plan targeted attacks, potentially leading to full system compromise through chained exploits using exposed version data.
Likely Case
Information leakage enables reconnaissance for further attacks, exposing system architecture and potentially sensitive configuration data.
If Mitigated
Limited exposure with proper network segmentation and access controls preventing external access to the vulnerable endpoint.
🎯 Exploit Status
Simple HTTP GET request to the vulnerable endpoint returns sensitive information without authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in available references
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-meta4-hr-cegid
Restart Required: No
Instructions:
1. Consult vendor for patch availability 2. Remove or restrict access to '/sitetest/english/dumpenv.jsp' 3. Apply vendor-recommended updates when available
🔧 Temporary Workarounds
Block vulnerable endpoint
allRestrict access to the '/sitetest/english/dumpenv.jsp' endpoint using web server configuration or firewall rules
# Apache: RewriteRule ^/sitetest/english/dumpenv\.jsp$ - [F]
# Nginx: location ~ ^/sitetest/english/dumpenv\.jsp$ { return 403; }
# IIS: Add request filtering rule to block /sitetest/english/dumpenv.jsp
Remove diagnostic files
allDelete or rename the vulnerable JSP file from the web application directory
# Linux: rm /path/to/webapp/sitetest/english/dumpenv.jsp
# Windows: del C:\path\to\webapp\sitetest\english\dumpenv.jsp
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach the Meta4 HR application
- Deploy a web application firewall (WAF) with rules to block requests to the vulnerable endpoint
🔍 How to Verify
Check if Vulnerable:
Send HTTP GET request to http://[target]/sitetest/english/dumpenv.jsp and check if it returns system informationCheck Version:
Check Meta4 HR version through admin interface or consult vendor documentationVerify Fix Applied:
Attempt the same request after remediation - should return 403/404 error or no sensitive data📡 Detection & Monitoring
Log Indicators:
