CVE-2022-22262
📋 TL;DR
CVE-2022-22262 is a local privilege escalation vulnerability in ROG Live Service where improper symbolic link handling allows unauthenticated local attackers to delete arbitrary system files. This can disrupt system services and potentially cause denial of service. Affected systems include ASUS ROG devices running vulnerable versions of ROG Live Service.
💻 Affected Systems
- ASUS ROG Live Service
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through deletion of critical system files, leading to system crashes, data loss, or persistent denial of service requiring OS reinstallation.
Likely Case
Local attackers delete important system files causing service disruptions, application failures, or system instability requiring administrative intervention.
If Mitigated
Limited impact with proper access controls and monitoring, potentially causing temporary service disruption but no persistent damage.
🎯 Exploit Status
Exploitation requires local access but no authentication. Attack involves creating symbolic links to target system files before the service deletes its temp files.

🔧 Temporary Workarounds
Disable ROG Live Service
windowsTemporarily disable the vulnerable service until patching is possible
sc stop "ASUS ROG Live Service"
sc config "ASUS ROG Live Service" start= disabled
Restrict symbolic link creation
windowsConfigure Windows to restrict symbolic link creation to administrators only
secedit /export /cfg config.inf
Edit config.inf to set SeCreateSymbolicLinkPrivilege = *S-1-5-32-544
secedit /configure /db config.sdb /cfg config.inf
🧯 If You Can't Patch
- Remove or disable ROG Live Service from affected systems
- Implement strict access controls to prevent unauthorized local access to vulnerable systems
