CVE-2025-2762
📋 TL;DR
This vulnerability allows local attackers with initial low-privileged access to escalate privileges on CarlinKit CPC200-CCPA devices by exploiting a missing hardware root of trust configuration. Attackers can execute arbitrary code during the boot process, potentially gaining full system control. Only users of CarlinKit CPC200-CCPA devices are affected.
💻 Affected Systems

📦 What is this software?
Autokit by Carlinkit
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise allowing persistent backdoor installation, data theft, and use as a foothold for network attacks.
Likely Case
Local privilege escalation enabling unauthorized access to sensitive device functions and data.
If Mitigated
Limited impact if proper network segmentation and access controls prevent initial low-privileged access.
🎯 Exploit Status
Requires existing low-privileged access to the device. Exploitation involves manipulating boot process through hardware trust chain weakness.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.zerodayinitiative.com/advisories/ZDI-25-176/
Restart Required: Yes
Instructions:
1. Contact CarlinKit vendor for firmware update. 2. Backup device configuration. 3. Apply firmware update following vendor instructions. 4. Reboot device. 5. Verify boot integrity.
🔧 Temporary Workarounds
Restrict Physical and Network Access
allPrevent initial low-privileged access by limiting who can interact with the device.
Network Segmentation
allIsolate CarlinKit devices on separate VLANs with strict firewall rules.
🧯 If You Can't Patch
- Replace vulnerable devices with updated hardware models
- Implement strict access controls and monitoring for all CarlinKit device interactions
🔍 How to Verify
Check if Vulnerable:
Check device model and firmware version against vendor advisory. If device is CarlinKit CPC200-CCPA, assume vulnerable unless confirmed patched.Check Version:
Check device settings or vendor documentation for firmware version command (varies by implementation)Verify Fix Applied:
Verify firmware version matches vendor's patched version and check boot integrity measurements if supported.📡 Detection & Monitoring
