CVE-2025-59713
📋 TL;DR
CVE-2025-59713 is an unsafe deserialization vulnerability in Snipe-IT versions before 8.1.18 that could allow remote code execution. This affects all organizations using vulnerable Snipe-IT instances for IT asset management. Attackers could exploit this to execute arbitrary code on the server.
💻 Affected Systems
- Snipe-IT
📦 What is this software?
Snipe It by Snipeitapp
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, and lateral movement within the network.
Likely Case
Remote code execution allowing attackers to gain shell access, install malware, or exfiltrate sensitive asset management data.
If Mitigated
Limited impact if proper network segmentation and least privilege principles are implemented, though RCE would still be possible.
🎯 Exploit Status
Deserialization vulnerabilities typically require some authentication or specific conditions to trigger, but successful exploitation leads to RCE.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 8.1.18
Vendor Advisory: https://github.com/grokability/snipe-it/releases/tag/v8.1.18
Restart Required: No
Instructions:
1. Backup your Snipe-IT database and files. 2. Update to version 8.1.18 via git pull or download from releases. 3. Run 'composer install --no-dev' to update dependencies. 4. Run 'php artisan migrate' to update database schema if needed.
🔧 Temporary Workarounds
Input Validation Enhancement
allImplement additional input validation for serialized data processing endpoints
🧯 If You Can't Patch
- Implement strict network access controls to limit Snipe-IT access to authorized users only
- Deploy web application firewall (WAF) rules to detect and block deserialization attacks
🔍 How to Verify
Check if Vulnerable:
Check Snipe-IT version in admin panel or via 'php artisan --version' commandCheck Version:
php artisan --versionVerify Fix Applied:
Confirm version is 8.1.18 or later and test serialization functionality📡 Detection & Monitoring
Log Indicators:
- Unusual PHP deserialization errors
- Suspicious POST requests to serialization endpoints
- Unexpected process execution
Network Indicators:
- Unusual outbound connections from Snipe-IT server
- Suspicious payloads in HTTP requests
