CVE-2024-45999
📋 TL;DR
A SQL injection vulnerability in Cloudlog 2.6.15 allows attackers to execute arbitrary SQL commands via the station_id parameter in the get_station_info() function. This affects all Cloudlog installations running version 2.6.15 or earlier. Attackers can potentially access, modify, or delete database contents.
💻 Affected Systems

Cloudlog by Magicbug
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, or remote code execution via database functions.
Likely Case
Unauthorized data access, privilege escalation, or data manipulation within the Cloudlog database.
If Mitigated
Limited impact with proper input validation and database permissions restricting damage to non-critical data.
🎯 Exploit Status
SQL injection via GET/POST parameters requires minimal technical skill to exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.6.16 or later
Vendor Advisory: https://github.com/magicbug/Cloudlog
Restart Required: No
Instructions:
1. Backup your Cloudlog installation and database. 2. Download the latest version from GitHub. 3. Replace the vulnerable file /application/models/Oqrs_model.php with the patched version. 4. Verify the fix by testing the station_id parameter.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to sanitize station_id parameter before processing.
Modify /application/models/Oqrs_model.php to validate station_id as integer using is_numeric() or similar function
Web Application Firewall
allDeploy WAF rules to block SQL injection patterns in station_id parameter.
Add WAF rule: block requests containing SQL keywords like UNION, SELECT, INSERT in station_id parameter
🧯 If You Can't Patch
- Restrict database user permissions to read-only access for the Cloudlog application.
- Implement network segmentation to isolate Cloudlog server from critical systems.
🔍 How to Verify
Check if Vulnerable:
Test station_id parameter with SQL injection payload like ' OR '1'='1 and check for unexpected database responses.Check Version:
Check Cloudlog version in /application/config/config.php or admin interface.Verify Fix Applied:
Attempt SQL injection on station_id parameter after patching - should return error or no data instead of executing SQL.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts following SQL injection patterns
- Database queries with unusual syntax in station_id parameter
Network Indicators:
- HTTP requests containing SQL keywords in station_id parameter
- Abnormal database connection patterns from web server
SIEM Query:
source="web_logs" AND (station_id CONTAINS "UNION" OR station_id CONTAINS "SELECT" OR station_id CONTAINS "INSERT")
