Executive Summary
A critical vulnerability (CVE-2026-40624) in AVer PTC cameras poses a severe risk to enterprises, with a CVSS v3 score of 9.8. Exploitation could allow remote, unauthenticated attackers to execute arbitrary code, potentially compromising critical infrastructure sectors such as Government Services, Commercial Facilities, and Healthcare. Immediate patching is essential to mitigate this high-risk threat.
Threat Analysis
The vulnerability stems from improper input validation in AVer PTC500S, PTC115, PTC500+, and PTC115+ cameras. Attackers can exploit this flaw via a specially crafted web request, enabling arbitrary code execution without authentication. The affected versions include all iterations of the listed models. This exploit leverages CWE-552, which involves files or directories accessible to external parties, making it a high-priority threat for organizations using these devices.
Business Impact Assessment
The exploitation of this vulnerability could lead to operational disruptions, financial losses, and reputational damage, particularly in sectors reliant on video surveillance for security. Given the widespread deployment of these cameras globally, the potential for large-scale compromise is significant. Enterprises must prioritize remediation to avoid costly breaches and regulatory penalties.
SOC Recommendations — Immediate Actions
- Apply the firmware fix provided by AVer: Download Link.
- Isolate AVer PTC cameras from external internet access until patched.
- Monitor network traffic for unusual web requests targeting these devices.
- Conduct a vulnerability scan to identify unpatched AVer PTC cameras.
MITRE ATT&CK Mapping
- Initial Access: Exploit Public-Facing Application (T1190).
- Execution: Command and Scripting Interpreter (T1059).
Detection Opportunities
Monitor web server logs for anomalous HTTP requests targeting AVer PTC cameras. Look for patterns indicative of crafted requests attempting to exploit improper input validation. Network IDS/IPS systems should be configured to detect suspicious traffic to these devices.
Threat Hunting Recommendations
- Search for unusual process execution originating from AVer PTC cameras.
- Investigate logs for repeated failed web requests targeting these devices.
- Identify any unauthorized changes to camera firmware or configurations.
