📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including authentication bypass, data exfiltration, privilege escalation, and potential remote code execution if database functions allow it.
Likely Case
Authentication bypass leading to unauthorized system access, data theft of member information, and potential manipulation of gym management data.
If Mitigated
Limited impact if proper input validation and WAF rules are in place, though SQL injection attempts may still be logged.
🎯 Exploit Status
Exploit code is publicly available and targets a common SQL injection pattern in authentication endpoints.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.campcodes.com/
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates. Consider implementing parameterized queries and input validation in the /ajax.php login handler.
🔧 Temporary Workarounds
Web Application Firewall Rule
allImplement WAF rules to block SQL injection patterns in the Username parameter
# Example ModSecurity rule: SecRule ARGS:Username "@detectSQLi" "id:1001,phase:2,deny,status:403"
Input Validation Filter
linuxAdd server-side validation to reject suspicious characters in Username field
# PHP example: if(preg_match('/[\'\"\;\-\#\*]/', $_POST['Username'])) { die('Invalid input'); }
🧯 If You Can't Patch
- Isolate the system behind a reverse proxy with strict input validation
- Implement network segmentation to limit access to the vulnerable endpoint
🔍 How to Verify
Check if Vulnerable:
Test the /ajax.php?action=login endpoint with SQL injection payloads in the Username parameter (e.g., admin' OR '1'='1)Check Version:
Check the system's about page or configuration files for version informationVerify Fix Applied:
Verify that SQL injection attempts return error messages or are blocked, and that parameterized queries are implemented📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in web server logs
- Multiple failed login attempts with special characters
- Unusual database queries from web application
Network Indicators:
- HTTP POST requests to /ajax.php with SQL keywords in parameters
- Unusual traffic patterns to login endpoint
SIEM Query:
source="web_logs" AND (url="/ajax.php" AND (param="Username" AND value MATCHES "[';\-]|OR|UNION|SELECT"))
