CVE-2025-8108
📋 TL;DR
This CVE describes a privilege escalation vulnerability in Axis devices where improper permissions and lack of input validation in ACAP configuration files could allow attackers to gain elevated privileges. The vulnerability requires victims to install malicious unsigned ACAP applications on devices configured to allow such installations. This affects Axis device users who have enabled unsigned ACAP application installation.
💻 Affected Systems
- Axis devices with ACAP capability
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise with root/system-level access, allowing attackers to install persistent backdoors, exfiltrate data, or pivot to other network resources.
Likely Case
Local privilege escalation to gain administrative control over the affected Axis device, potentially enabling surveillance manipulation or denial of service.
If Mitigated
No impact if devices are configured to only allow signed ACAP applications or if ACAP application installation is disabled.
🎯 Exploit Status
Exploitation requires social engineering to convince victims to install malicious ACAP applications and requires devices to be configured to allow unsigned applications.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Axis security advisory for specific firmware versions
Vendor Advisory: https://www.axis.com/dam/public/38/20/aa/cve-2025-8108pdf-en-US-504218.pdf
Restart Required: Yes
Instructions:
1. Download latest firmware from Axis support portal. 2. Backup device configuration. 3. Apply firmware update via web interface or management tool. 4. Verify successful update and restore configuration if needed.
🔧 Temporary Workarounds
Disable unsigned ACAP applications
allConfigure devices to only allow installation of signed ACAP applications
Restrict ACAP installation permissions
allLimit who can install ACAP applications through access controls
🧯 If You Can't Patch
- Configure devices to only accept signed ACAP applications from trusted sources
- Implement network segmentation to isolate Axis devices from critical network segments
🔍 How to Verify
Check if Vulnerable:
Check device configuration for ACAP installation settings and verify if unsigned applications are allowedCheck Version:
Check device web interface or use Axis Device Manager to view firmware versionVerify Fix Applied:
Verify firmware version matches patched version from Axis advisory and test that unsigned ACAP applications cannot be installed📡 Detection & Monitoring
Log Indicators:
- Unauthorized ACAP application installation attempts
- Privilege escalation attempts in system logs
- Unexpected process execution with elevated privileges
Network Indicators:
- Unusual outbound connections from Axis devices
- ACAP package downloads from untrusted sources
