Marksoft by Marksoft
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data exfiltration, authentication bypass, privilege escalation, and potential remote code execution on the underlying server.
Likely Case
Unauthorized data access, authentication bypass, and potential data manipulation or deletion in the Marksoft database.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation preventing database access.
🎯 Exploit Status
SQL injection vulnerabilities typically have low exploitation complexity and can be exploited without authentication if the vulnerable endpoint is exposed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.usom.gov.tr/bildirim/tr-23-0363
Restart Required: No
Instructions:
1. Monitor vendor for security updates. 2. Apply patches immediately when available. 3. Test patches in non-production environment first.

Network Segmentation
allRestrict database access to only necessary application servers
🧯 If You Can't Patch
- Implement input validation and parameterized queries in application code
- Disable or restrict access to vulnerable endpoints if not required
🔍 How to Verify
Check if Vulnerable:
Check Marksoft version numbers against affected versions. Test endpoints with SQL injection payloads in controlled environment.Check Version:
Check Marksoft administration interface or configuration files for version informationVerify Fix Applied:
Verify updated version numbers and test with SQL injection payloads to confirm remediation.📡 Detection & Monitoring
Log Indicators:
