CVE-2025-13716
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code as root on Tencent MimicMotion installations through deserialization of untrusted data in the create_pipeline function. Attackers can exploit this by tricking users into visiting malicious web pages or opening malicious files. All users of vulnerable Tencent MimicMotion versions are affected.

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with root privileges leading to complete system compromise, data theft, and persistent backdoor installation.
Likely Case
Attackers executing arbitrary code in the context of the application, potentially escalating to root privileges for lateral movement and data exfiltration.
If Mitigated
Limited impact with proper network segmentation, application sandboxing, and user privilege restrictions preventing full system compromise.
🎯 Exploit Status
Exploitation requires user interaction (visiting malicious page or opening malicious file). The vulnerability is documented in ZDI-CAN-27208 with technical details available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Commit 6907bdcc259a6a048d41a365e840d22274f9256c or later
Vendor Advisory: https://github.com/Tencent/MimicMotion/commit/6907bdcc259a6a048d41a365e840d22274f9256c
Restart Required: Yes
Instructions:
1. Update Tencent MimicMotion to commit 6907bdcc259a6a048d41a365e840d22274f9256c or later. 2. Restart the MimicMotion service. 3. Verify the fix by checking the version/commit hash.
🔧 Temporary Workarounds
Restrict Network Access
linuxLimit network exposure of MimicMotion instances to trusted networks only
iptables -A INPUT -p tcp --dport [MimicMotion_port] -s [trusted_network] -j ACCEPT
iptables -A INPUT -p tcp --dport [MimicMotion_port] -j DROP
Application Sandboxing
linuxRun MimicMotion in a container or with reduced privileges
docker run --security-opt no-new-privileges -u nobody [mimicmotion_image]
🧯 If You Can't Patch
- Implement strict input validation and sanitization for all user-supplied data before deserialization
- Deploy web application firewall (WAF) rules to detect and block deserialization attacks
🔍 How to Verify
Check if Vulnerable:
Check if your MimicMotion version is prior to commit 6907bdcc259a6a048d41a365e840d22274f9256cCheck Version:
git log --oneline -1 (if installed from source) or check package versionVerify Fix Applied:
Verify the installed version includes commit 6907bdcc259a6a048d41a365e840d22274f9256c or later📡 Detection & Monitoring
Log Indicators:
- Unusual process creation from MimicMotion
- Deserialization errors or exceptions in application logs
- Unexpected network connections from MimicMotion process
Network Indicators:
- Suspicious HTTP requests containing serialized objects to MimicMotion endpoints
- Outbound connections from MimicMotion to unknown external IPs
SIEM Query:
process_name="mimicmotion" AND (parent_process!="expected_parent" OR command_line CONTAINS "suspicious_pattern")
