📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, or full system takeover via SQL injection to execute arbitrary commands.
Likely Case
Unauthorized data access, modification of scheduling data, or extraction of sensitive information from the database.
If Mitigated
Limited impact with proper input validation and database permissions restricting damage to non-critical data.
🎯 Exploit Status
Exploit details are publicly available, making this easily exploitable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
1. Check vendor website for updates. 2. If no patch available, implement workarounds. 3. Consider replacing with supported software.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd parameter validation and sanitization to /addtime.php to prevent SQL injection.
Modify /addtime.php to use prepared statements or parameterized queries for starttime/endtime parameters.
Access Restriction
allRestrict access to /addtime.php file.
Add .htaccess rules to block external access or move file to protected directory.
🧯 If You Can't Patch
- Implement web application firewall (WAF) with SQL injection rules
- Isolate the system on separate network segment with strict access controls
🔍 How to Verify
Check if Vulnerable:
Test /addtime.php with SQL injection payloads in starttime/endtime parameters and observe database errors or unexpected behavior.Check Version:
Check software documentation or configuration files for version information.Verify Fix Applied:
Attempt SQL injection tests after implementing fixes and confirm no database errors or unauthorized access occurs.📡 Detection & Monitoring
Log Indicators:
- Unusual database queries from web server
- SQL syntax errors in application logs
- Multiple failed parameter validation attempts
Network Indicators:
- HTTP requests to /addtime.php with SQL keywords in parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/addtime.php" AND (param="starttime" OR param="endtime") AND (content CONTAINS "UNION" OR content CONTAINS "SELECT" OR content CONTAINS "OR 1=1")
