⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, privilege escalation, authentication bypass, or full system takeover if database permissions allow command execution.
Likely Case
Unauthorized data access, privilege escalation to administrative roles, or user account manipulation.
If Mitigated
Limited impact with proper input validation, parameterized queries, and database permission restrictions in place.
🎯 Exploit Status
SQL injection via roleId parameter requires some level of access to affected modules. Public exploit details available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to newer versions if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation for roleId parameter to only accept expected values
Parameterized Queries
allRewrite affected SQL queries to use parameterized statements instead of string concatenation
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block SQL injection patterns
- Restrict access to editRole and deletUser modules to trusted users only
🔍 How to Verify
Check if Vulnerable:
Check CMS version in admin panel or configuration files. Test roleId parameter with SQL injection payloads in editRole/deletUser modules.Check Version:
Check CMS configuration files or admin dashboard for version informationVerify Fix Applied:
Verify input validation is implemented and parameterized queries are used. Test with SQL injection payloads to confirm they're blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts after roleId manipulation
- Unexpected database errors
Network Indicators:
- SQL injection patterns in HTTP requests to editRole/deletUser endpoints
SIEM Query:
source="web_logs" AND (uri="*editRole*" OR uri="*deletUser*") AND (query="*' OR *" OR query="*;--*" OR query="*UNION*" OR query="*SELECT*" OR query="*INSERT*" OR query="*UPDATE*")
