CVE-2025-54158
📋 TL;DR
A missing authentication vulnerability in Synology BeeDrive desktop software allows local users to execute arbitrary code without proper authentication. This affects users running BeeDrive desktop versions before 1.4.2-13960 on their local systems. Attackers with local access can exploit this to gain elevated privileges.
💻 Affected Systems
- Synology BeeDrive for desktop
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining administrative privileges, installing persistent malware, accessing sensitive data, and pivoting to other systems.
Likely Case
Local privilege escalation allowing attackers to execute arbitrary code with elevated permissions, potentially leading to data theft or system manipulation.
If Mitigated
Limited impact if proper network segmentation and least privilege principles are enforced, though local compromise risk remains.
🎯 Exploit Status
Requires local access but no authentication for the critical function. Attack vectors unspecified in advisory but likely involves local API calls or inter-process communication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.4.2-13960
Vendor Advisory: https://www.synology.com/en-global/security/advisory/Synology_SA_25_08
Restart Required: Yes
Instructions:
1. Open Synology BeeDrive desktop application. 2. Navigate to Settings > About. 3. Check for updates and install version 1.4.2-13960 or later. 4. Restart the application and system if prompted.
🔧 Temporary Workarounds
Disable BeeDrive Service
allTemporarily disable the BeeDrive desktop application to prevent exploitation until patching is possible.
Windows: sc stop BeeDriveService
macOS: sudo launchctl unload /Library/LaunchDaemons/com.synology.beedrive.plist
Linux: sudo systemctl stop beedrive
Restrict Local Access
allImplement strict access controls to limit which users can log into systems running BeeDrive.
🧯 If You Can't Patch
- Uninstall BeeDrive desktop software completely from affected systems.
- Implement application whitelisting to prevent unauthorized code execution from BeeDrive processes.
🔍 How to Verify
Check if Vulnerable:
Check BeeDrive desktop application version in Settings > About. If version is below 1.4.2-13960, system is vulnerable.Check Version:
Windows: wmic product where name="Synology BeeDrive" get version
macOS: defaults read /Applications/Synology\ BeeDrive.app/Contents/Info.plist CFBundleShortVersionString
Linux: dpkg -l | grep beedriveVerify Fix Applied:
Confirm BeeDrive desktop application shows version 1.4.2-13960 or higher in Settings > About.📡 Detection & Monitoring
