CVE-2024-10501
📋 TL;DR
This critical SQL injection vulnerability in ESAFENET CDG 5 allows remote attackers to execute arbitrary SQL commands by manipulating the 'id' parameter in the findById function. This can lead to unauthorized data access, modification, or deletion. All users running vulnerable versions of ESAFENET CDG 5 are affected.

Cdg by Esafenet
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data destruction, and potential remote code execution via database functions.
Likely Case
Unauthorized access to sensitive data stored in the database, including user credentials, personal information, and system configuration.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only allowing data viewing without modification.
🎯 Exploit Status
Exploit details have been publicly disclosed, making weaponization straightforward for attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes
Instructions:
1. Contact ESAFENET for patch information. 2. If no patch available, implement workarounds. 3. Monitor vendor communications for updates.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for the 'id' parameter to only accept expected values
Implement parameterized queries in ExamCDGDocService.java
Add input validation: if (!id.matches("^[0-9]+$")) { throw new IllegalArgumentException(); }
WAF Rule
allDeploy web application firewall rules to block SQL injection patterns
Configure WAF to block requests containing SQL keywords in the id parameter
Implement rate limiting on /com/esafenet/servlet/document/ExamCDGDocService endpoints
🧯 If You Can't Patch
- Isolate the vulnerable system behind a reverse proxy with strict input validation
- Implement network segmentation to limit database access from the application server
🔍 How to Verify
Check if Vulnerable:
Test the findById endpoint with SQL injection payloads like: id=1' OR '1'='1Check Version:
Check application version through admin interface or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer work and that parameterized queries are implemented📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple requests with SQL keywords in parameters
- Requests to /com/esafenet/servlet/document/ExamCDGDocService with suspicious id values
Network Indicators:
- Unusual database connection patterns from application server
- Large data transfers from database to external IPs
SIEM Query:
source="application.log" AND ("SQL" OR "syntax" OR "union" OR "select") AND uri="/com/esafenet/servlet/document/ExamCDGDocService"
