📋 TL;DR
This critical SQL injection vulnerability in 07FLY CRM V2 allows attackers to manipulate database queries through the administrator login page. Attackers can potentially steal sensitive data, modify database contents, or gain unauthorized access. All systems running vulnerable versions of 07FLY CRM V2 with the affected login component are at risk.
💻 Affected Systems
- 07FLY CRM V2
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, privilege escalation to administrator, and potential system takeover.
Likely Case
Unauthorized access to sensitive CRM data, credential theft, and potential lateral movement within the network.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or failed login attempts.
🎯 Exploit Status
Exploit code is publicly available on GitHub, making this easily exploitable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates or consider upgrading to a newer version if available.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement parameterized queries or prepared statements for the login_auth function to prevent SQL injection.
Modify /index.php/sysmanage/Login/login_auth/ to use prepared statements with PDO or mysqli
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests.
Configure WAF rules to detect and block SQL injection patterns in login requests
🧯 If You Can't Patch
- Isolate the CRM system from the internet and restrict access to trusted IP addresses only.
- Implement network segmentation to limit potential lateral movement if compromised.
🔍 How to Verify
Check if Vulnerable:
Test the /index.php/sysmanage/Login/login_auth/ endpoint with SQL injection payloads in the 'account' parameter.Check Version:
Check CRM version in admin panel or configuration files; specific version detection method depends on installation.Verify Fix Applied:
Verify that SQL injection attempts no longer succeed and that prepared statements are implemented in the login_auth function.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts with SQL syntax in parameters
- Unexpected database queries from login endpoint
Network Indicators:
- HTTP requests to /index.php/sysmanage/Login/login_auth/ containing SQL keywords like UNION, SELECT, OR 1=1
SIEM Query:
source="web_logs" AND uri="/index.php/sysmanage/Login/login_auth/" AND (param="account" AND value MATCH "'.*[Uu][Nn][Ii][Oo][Nn].*|.*[Ss][Ee][Ll][Ee][Cc][Tt].*|.*[Oo][Rr].*1=1.*")
