| Title | SeaCMS 13.3 SQL Injection |
|---|
| Description | Multiple SQL injection vulnerabilities exist in the SeaCMS backend video management module. The vulnerable code uses `implode()` to concatenate array elements directly into SQL queries without proper sanitization.
**⚠️ CRITICAL: Unlike frontend vulnerabilities, the backend disables SQL security checks!**
**Vulnerability Characteristics:**
- **Authentication Required**: Backend administrator access needed
- **Multiple Injection Points**: Lines 260, 293, 318, 326
- **WAF Protection**: ❌ DISABLED in backend (`$dsql->safeCheck = false`)
- **Fully Exploitable**: ✅ YES - UNION and time-based blind injection confirmed
