CVE-2019-9083
📋 TL;DR
SQLiteManager versions 1.20 and 1.24 contain a SQL injection vulnerability in the dbsel parameter of main.php. This allows attackers to execute arbitrary SQL commands on the database. Since the product is discontinued, affected users remain vulnerable unless they implement workarounds.

⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, or deletion of entire databases. Could lead to full system compromise if database privileges allow file system access.
Likely Case
Unauthorized data access and extraction from SQLite databases managed by the application. Attackers can read, modify, or delete database contents.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented, restricting SQL injection attempts.
🎯 Exploit Status
SQL injection via URL parameter requires minimal technical skill. Public exploit details available in disclosure.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: N/A
Vendor Advisory: N/A
Restart Required: No
Instructions:
No official patch available since product is discontinued. Migrate to alternative SQLite management tools.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize the dbsel parameter before processing
Modify main.php to validate dbsel parameter using preg_match('/^[a-zA-Z0-9_-]+$/', $_GET['dbsel']) or similar
Web Application Firewall
allDeploy WAF with SQL injection protection rules
Configure ModSecurity with OWASP CRS rules
Enable SQL injection protection in cloud WAF services
🧯 If You Can't Patch
- Remove SQLiteManager from internet-facing systems immediately
- Restrict access to SQLiteManager using network segmentation and firewall rules
🔍 How to Verify
Check if Vulnerable:
Check if SQLiteManager version is 1.20 or 1.24 by examining application files or version metadataCheck Version:
grep -r 'version.*1\.20\|1\.24' /path/to/sqlitemanager/ or check main.php header commentsVerify Fix Applied:
Test dbsel parameter with SQL injection payloads like ' OR '1'='1 and verify no database interaction occurs📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- HTTP requests with SQL keywords in dbsel parameter
- Multiple failed login attempts or database errors
Network Indicators:
- HTTP requests containing SQL injection patterns to main.php
- Unusual outbound database connections from web server
SIEM Query:
source="web_logs" AND uri="/sqlitemanager/main.php" AND (query CONTAINS "UNION" OR query CONTAINS "SELECT" OR query CONTAINS "OR '1'='1'")
