⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data exfiltration, privilege escalation, authentication bypass, and potential remote code execution if database functions allow it.
Likely Case
Unauthorized access to sensitive employee records, personal identifiable information (PII) theft, and potential lateral movement within the database.
If Mitigated
Limited data exposure if proper input validation and parameterized queries are implemented, with minimal impact on system availability.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once credentials are obtained. The GitHub reference demonstrates the injection technique.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.4.2 or later
Vendor Advisory: https://cordyscrm.com/security/advisory/CVE-2025-70981
Restart Required: No
Instructions:
1. Backup your CordysCRM database and configuration files. 2. Download the latest version from the official CordysCRM repository. 3. Replace the vulnerable files with patched versions. 4. Verify the fix by testing the /user/list endpoint with malicious input.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side validation to restrict departmentIds parameter to numeric values only
Add input validation in the user list controller to accept only integers for departmentIds parameter
Web Application Firewall Rule
allBlock SQL injection patterns in the departmentIds parameter
Add WAF rule: deny requests to /user/list containing SQL keywords in departmentIds parameter
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries for all user inputs
- Restrict database user permissions to minimum required access and implement network segmentation
🔍 How to Verify
Check if Vulnerable:
Test the /user/list endpoint with departmentIds parameter containing SQL injection payload like '1 OR 1=1--' and observe if database errors or unexpected data is returnedCheck Version:
Check CordysCRM version in admin panel or configuration filesVerify Fix Applied:
Attempt the same SQL injection test after patching - should receive proper error handling or no data leakage📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts followed by /user/list access
- Requests to /user/list with non-numeric departmentIds values
Network Indicators:
- Unusual database connection patterns from web server
- Large data transfers from database following /user/list requests
SIEM Query:
source="web_logs" AND uri="/user/list" AND (departmentIds="*OR*" OR departmentIds="*UNION*" OR departmentIds="*SELECT*" OR departmentIds="*--*")
