⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, modification, deletion, and potential remote code execution via database functions.
Likely Case
Data exfiltration, privilege escalation, and unauthorized access to sensitive information stored in the database.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation in place.
🎯 Exploit Status
SQL injection is well-understood with many automated tools available. The vulnerability affects multiple parameters, making exploitation straightforward.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions above those listed in affected versions
Vendor Advisory: https://www.hyland.com/en/security-advisories
Restart Required: Yes
Instructions:
1. Contact Hyland support for specific patch versions. 2. Apply the security update provided by Hyland. 3. Restart OnBase services. 4. Test application functionality.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns in the vulnerable parameters
Input Validation
allImplement strict input validation for TableName, ColumnName, Name, UserId, and Password parameters
🧯 If You Can't Patch
- Implement network segmentation to isolate OnBase servers from untrusted networks
- Deploy database activity monitoring to detect SQL injection attempts
🔍 How to Verify
Check if Vulnerable:
Test parameters with SQL injection payloads (e.g., ' OR '1'='1) in TableName, ColumnName, Name, UserId, or Password fieldsCheck Version:
Check OnBase version in administration console or via Hyland documentationVerify Fix Applied:
Verify version is above affected ranges and test SQL injection attempts are properly rejected📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts with SQL patterns
- Long parameter values in web server logs
Network Indicators:
- SQL keywords in HTTP parameters
- Unusual database connection patterns from application servers
SIEM Query:
source="web_logs" AND (param="*SELECT*" OR param="*UNION*" OR param="*OR*1=1*")
