⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, or full system takeover through SQL injection leading to remote code execution.
Likely Case
Unauthorized data extraction from the database, including sensitive meeting records, user credentials, or organizational information.
If Mitigated
Limited impact with proper input validation and WAF protection, potentially only causing application errors.
🎯 Exploit Status
Exploit requires crafting POST requests with malicious SQL in idtyp and idgremium parameters. Public exploit code is available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 4.7.3c
Vendor Advisory: https://www.sitzungsdienst.net/2018/12/sd-net-rim-4-7-3-veroeffentlicht/
Restart Required: Yes
Instructions:
1. Download SD.NET RIM version 4.7.3c or later from the vendor website. 2. Backup current installation and database. 3. Install the updated version following vendor instructions. 4. Restart the application service.
🔧 Temporary Workarounds
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns in POST parameters
Input Validation Filter
allImplement server-side input validation to sanitize idtyp and idgremium parameters
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries for the /vorlagen/ endpoint
- Restrict network access to the SD.NET RIM application using firewall rules
🔍 How to Verify
Check if Vulnerable:
Test by sending POST requests to /vorlagen/ with SQL injection payloads in idtyp and idgremium parametersCheck Version:
Check application version in admin interface or configuration filesVerify Fix Applied:
Verify version is 4.7.3c or later and test that SQL injection attempts no longer succeed📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- POST requests to /vorlagen/ with suspicious parameter values
- Database error messages containing SQL syntax
Network Indicators:
