  • Cloudlog
Versions: 2.6.15
Operating Systems: All
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerability exists in the default installation and requires no special configuration to be exploitable.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete database compromise leading to data theft, data destruction, and potential remote code execution via database functions.

🟠

Likely Case

Database information disclosure, data manipulation, and potential privilege escalation within the application.

🟢

If Mitigated

Limited impact if database permissions are properly restricted and input validation is enforced at other layers.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

The vulnerability is unauthenticated and trivial to exploit with publicly available proof-of-concept code.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 2.6.16 or later

Vendor Advisory: https://www.magicbug.co.uk/cloudlog/

Restart Required: No

Instructions:

1. Backup your Cloudlog installation and database. 2. Download the latest version from the official GitHub repository. 3. Replace the affected files with the patched version. 4. Verify the fix by checking the version number.

🔧 Temporary Workarounds

Temporary Access Restriction

all

Restrict access to the vulnerable endpoint using web server configuration or firewall rules.

# Apache: Add to .htaccess
<Files "Oqrs.php">
    Deny from all
</Files>
# Nginx: Add to server block
location ~* Oqrs\.php$ {
    deny all;
}

Input Validation WAF Rule

all

Implement web application firewall rules to block SQL injection patterns in the id parameter.

# ModSecurity rule example
SecRule ARGS:id "@detectSQLi" \
    "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"
# Cloudflare WAF: Enable SQL Injection protection

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate the Cloudlog server from critical systems.
  • Enable detailed logging and monitoring for SQL injection attempts and unusual database queries.

🔍 How to Verify

Check if Vulnerable:

Check if your Cloudlog installation is version 2.6.15 by examining the version file or admin panel.

Check Version:

grep -r "version" /path/to/cloudlog/application/config/version.php

Verify Fix Applied:

Verify the version has been updated to 2.6.16 or later and test the vulnerable endpoint with safe SQL injection payloads.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL queries in database logs
  • Multiple failed delete_oqrs_line requests
  • Requests with SQL injection patterns in the id parameter

Network Indicators:

  • HTTP POST requests to Oqrs.php with SQL payloads in parameters
  • Unusual database connection patterns from web server

SIEM Query:

source="web_logs" AND uri="*Oqrs.php*" AND (param="*id=*UNION*" OR param="*id=*SELECT*" OR param="*id=*OR*1=1*")
