CVE-2025-64084
📋 TL;DR
An authenticated SQL injection vulnerability in Cloudlog 2.7.5 and earlier allows authenticated attackers to execute arbitrary SQL commands. This occurs because the vucc_details_ajax function fails to properly sanitize user-supplied Gridsquare POST parameters before concatenating them into raw SQL queries. Only authenticated users can exploit this vulnerability.
💻 Affected Systems
- Cloudlog
📦 What is this software?
Cloudlog by Magicbug
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data exfiltration, modification, or deletion; potential privilege escalation to administrative access; and possible remote code execution if database functions allow it.
Likely Case
Unauthorized data access and extraction of sensitive information from the Cloudlog database, including user credentials, logs, and configuration data.
If Mitigated
Limited impact due to proper input validation and parameterized queries preventing SQL injection, with authenticated access still required for exploitation.
🎯 Exploit Status
Exploitation requires authenticated access to the Cloudlog application. The vulnerability is in a specific function (vucc_details_ajax) that handles Gridsquare parameters.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.7.6
Vendor Advisory: https://github.com/XY20130630/Cloudlog/security/advisories/GHSA-4r9r-3r3q-jg44
Restart Required: No
Instructions:
1. Backup your Cloudlog installation and database. 2. Download Cloudlog 2.7.6 from the official GitHub repository. 3. Replace the affected files with the patched versions. 4. Verify the fix by checking that the vucc_details_ajax function now properly sanitizes input.
🔧 Temporary Workarounds
Input Validation Filter
allImplement custom input validation for Gridsquare parameters to reject suspicious characters
Add input validation in application/controllers/Awards.php before processing Gridsquare parameters
WAF Rule
allDeploy web application firewall rules to block SQL injection patterns in POST requests
Configure WAF to detect and block SQL injection patterns in POST parameters
🧯 If You Can't Patch
- Implement strict input validation for all user-supplied parameters in the Awards controller
- Restrict database user permissions to minimize potential damage from successful exploitation
🔍 How to Verify
Check if Vulnerable:
Check if your Cloudlog version is 2.7.5 or earlier by examining the version file or checking the application interfaceCheck Version:
Check the version.txt file or application configuration for version informationVerify Fix Applied:
Verify that the application/controllers/Awards.php file contains the fix from commit 72a8c3d705c8629f60f64da9f37968417c980242📡 Detection & Monitoring
