CVE-2025-6298
📋 TL;DR
This CVE describes a privilege escalation vulnerability in Axis ACAP applications where improper input validation allows malicious applications to gain elevated privileges. It affects Axis devices configured to allow installation of unsigned ACAP applications. Attackers must convince victims to install a malicious ACAP application to exploit this vulnerability.
💻 Affected Systems
- Axis network devices with ACAP application support
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full device compromise with administrative privileges, allowing attackers to modify device configuration, install persistent backdoors, or pivot to other network resources.
Likely Case
Limited privilege escalation within the ACAP application sandbox, potentially allowing unauthorized access to device functions or data.
If Mitigated
No impact if devices are configured to only allow signed ACAP applications from trusted sources.
🎯 Exploit Status
Exploitation requires social engineering to convince users to install malicious ACAP applications. Requires device configuration that permits unsigned application installation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Axis security advisory for specific firmware versions
Vendor Advisory: https://www.axis.com/dam/public/ef/91/c3/cve-2025-6298pdf-en-US-504215.pdf
Restart Required: Yes
Instructions:
1. Access Axis device web interface
2. Navigate to System > Maintenance
3. Check for firmware updates
4. Download and install latest firmware from Axis website
5. Reboot device after installation
🔧 Temporary Workarounds
Disable unsigned ACAP applications
allConfigure device to only allow signed ACAP applications from trusted sources
Restrict ACAP installation permissions
allLimit which users can install ACAP applications on the device
🧯 If You Can't Patch
- Configure devices to only accept signed ACAP applications from trusted sources
- Implement network segmentation to isolate vulnerable devices from critical resources
- Educate users about risks of installing untrusted applications
🔍 How to Verify
Check if Vulnerable:
Check device configuration to see if unsigned ACAP applications are allowed. Review installed ACAP applications for unknown or suspicious entries.Check Version:
Check device web interface under System > Support > System Overview for firmware versionVerify Fix Applied:
Verify firmware version is updated to patched version. Confirm device configuration only allows signed ACAP applications.📡 Detection & Monitoring
Log Indicators:
- Unauthorized ACAP application installation attempts
- Privilege escalation attempts in application logs
