CVE-2025-65530
📋 TL;DR
This vulnerability allows attackers to execute arbitrary code as root by exploiting an eval injection in CloudLinux ai-bolit's malware de-obfuscation routines. Attackers can overwrite any file on the system by having the software scan a specially crafted malicious file. This affects all systems running vulnerable versions of ai-bolit, particularly web hosting environments using CloudLinux.
💻 Affected Systems
- CloudLinux ai-bolit
📦 What is this software?
Ai Bolit by Cloudlinux
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with root privileges, allowing attackers to install persistent backdoors, steal sensitive data, or disrupt services.
Likely Case
File system manipulation leading to privilege escalation, service disruption, or installation of cryptocurrency miners or other malware.
If Mitigated
Limited impact if proper file permissions and isolation are in place, but still significant due to root access potential.
🎯 Exploit Status
Exploitation requires ability to create or upload a file that gets scanned by ai-bolit, which is common in web hosting scenarios.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v32.7.4
Vendor Advisory: https://blog.imunify360.com/security-advisory-imunify-ai-bolit-vulnerability
Restart Required: No
Instructions:

🔧 Temporary Workarounds
Disable automatic scanning
linuxTemporarily disable ai-bolit's automatic file scanning until patched
systemctl stop ai-bolit
systemctl disable ai-bolit
Restrict file upload locations
allConfigure web applications to upload files to directories not scanned by ai-bolit
🧯 If You Can't Patch
- Implement strict file upload validation and sanitization in web applications
- Use file system permissions to restrict ai-bolit's access to sensitive directories
🔍 How to Verify
Check if Vulnerable:
Check ai-bolit version: 'ai-bolit --version' or 'rpm -q ai-bolit'Check Version:
ai-bolit --versionVerify Fix Applied:
Confirm version is 32.7.4 or higher: 'ai-bolit --version | grep -q "32.7.4" && echo "Patched"'📡 Detection & Monitoring
