CVE-2024-48259
📋 TL;DR
Cloudlog 2.6.15 contains an unauthenticated SQL injection vulnerability in the Oqrs.php request_form function via station_id or callsign parameters. This allows attackers to execute arbitrary SQL commands on the database. All Cloudlog installations running version 2.6.15 or earlier are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, privilege escalation to admin access, and potential remote code execution through database functions.
Likely Case
Unauthenticated attackers extracting sensitive user data, API keys, configuration secrets, and potentially gaining administrative access to the Cloudlog application.
If Mitigated
Limited information disclosure if database permissions are properly restricted and input validation is implemented at other layers.
🎯 Exploit Status
The vulnerability is in a public-facing endpoint with no authentication required. Exploitation requires only HTTP requests with crafted parameters.
🛠️ 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 current Cloudlog installation and database
2. Download the latest version from GitHub
3. Replace all files except config.php and uploads directory
4. Run any database migrations if required
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allImplement WAF rules to block SQL injection patterns in station_id and callsign parameters
Input Validation Filter
allAdd input validation to reject non-alphanumeric characters in station_id and callsign parameters
🧯 If You Can't Patch
- Restrict access to Cloudlog installation to trusted IP addresses only
- Implement database user with minimal permissions (read-only where possible)
🔍 How to Verify
Check if Vulnerable:
Check if your Cloudlog version is 2.6.15 or earlier. Test by sending crafted SQL injection payloads to /index.php/oqrs/request_form endpoint.Check Version:
Check application/config/config.php for version information or view footer on admin pagesVerify Fix Applied:
Verify version is 2.6.16 or later. Test that SQL injection payloads no longer execute and return error messages.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts following SQL errors
- Requests with SQL keywords in station_id or callsign parameters
Network Indicators:
- HTTP requests containing SQL injection patterns to /oqrs/request_form endpoint
- Unusual database connection patterns from web server
SIEM Query:
source="web_access.log" AND (uri="/index.php/oqrs/request_form" OR uri="/oqrs/request_form") AND (query_string="*station_id*" OR query_string="*callsign*") AND (query_string="*UNION*" OR query_string="*SELECT*" OR query_string="*INSERT*" OR query_string="*DELETE*")
