CVE-2023-45951 is a SQL injection vulnerability in lylme_spage v1.7.0 that allows attackers to execute arbitrary SQL commands via the $userip parameter. This affects all users running the vulnerable version of this software, potentially leading to unauthorized data access or system compromise.
💻 Affected Systems
- lylme_spage
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise allowing data theft, modification, or deletion, and potential remote code execution if database functions permit.
Likely Case
Unauthorized access to sensitive data stored in the database, including user credentials, personal information, or application data.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing SQL injection.
🎯 Exploit Status
SQL injection via user-controlled parameter is straightforward to exploit with common SQL injection techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check GitHub repository for latest version
Vendor Advisory: https://github.com/LyLme/lylme_spage/issues/32
Restart Required: No
Instructions:
1. Check the GitHub issue for patch details. 2. Update to the latest version of lylme_spage. 3. Replace vulnerable function.php with patched version.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation for the $userip parameter to only accept valid IP addresses.
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block malicious requests.
🧯 If You Can't Patch
- Implement network segmentation to isolate the vulnerable system from sensitive data and other critical systems.
- Deploy intrusion detection/prevention systems to monitor for SQL injection attempts and block malicious traffic.
🔍 How to Verify
Check if Vulnerable:
Check if running lylme_spage v1.7.0 and examine function.php for unvalidated $userip parameter usage in SQL queries.Check Version:
Check the application version in the source code or configuration files.Verify Fix Applied:
Verify that the $userip parameter is properly validated and SQL queries use parameterized statements or prepared statements.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL query patterns in application logs
- Multiple failed login attempts or database errors
Network Indicators:
- HTTP requests with SQL injection payloads in the userip parameter
- Unusual database connection patterns
SIEM Query:
search 'lylme_spage' AND ('SQL' OR 'injection' OR 'userip') in web server logs
