⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, or full system takeover via SQL injection to RCE escalation.
Likely Case
Unauthorized data access, data manipulation, or denial of service affecting the encryption policy management system.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation in place.
🎯 Exploit Status
Exploit details are publicly available, making this easily weaponizable. The vendor has not responded to disclosure attempts.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: Yes

🔧 Temporary Workarounds
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns targeting the vulnerable endpoint.
# WAF-specific rules would vary by platform
Input Validation Filter
allImplement application-level input validation to sanitize the 'id' parameter before processing.
# Application-specific code modifications required
🧯 If You Can't Patch
- Network segmentation: Isolate ESAFENET CDG 5 systems from untrusted networks and limit access to authorized users only.
- Monitoring and logging: Implement enhanced logging for SQL queries and monitor for suspicious database activity patterns.
🔍 How to Verify
Check if Vulnerable:
Check if the file /com/esafenet/servlet/system/EncryptPolicyTypeService.java exists and contains the vulnerable delEntryptPolicySort function with unsanitized 'id' parameter.Check Version:
# Check ESAFENET CDG version through application interface or configuration filesVerify Fix Applied:
Verify that SQL injection attempts against the vulnerable endpoint are properly blocked or that parameterized queries are implemented.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed login attempts or parameter manipulation
- Database error messages containing SQL syntax
Network Indicators:
- HTTP requests to /com/esafenet/servlet/system/EncryptPolicyTypeService with SQL injection patterns in parameters
- Unusual database connection patterns
SIEM Query:
source="application_logs" AND ("delEntryptPolicySort" OR "EncryptPolicyTypeService") AND (sql OR injection OR union OR select)
