CVE-2025-63408 is a directory traversal vulnerability affecting Local Agent DVR software versions through 6.6.1.0. The flaw allows an unauthenticated attacker with local access to traverse directories beyond the intended scope, enabling unauthorized access to sensitive files. This can lead to disclosure of confidential information stored on the system. Additionally, the vulnerability enables server-side request forgery (SSRF), allowing the attacker to make arbitrary requests from the server to internal or external resources, potentially bypassing network restrictions. More critically, the attacker can execute arbitrary operating system commands, which could lead to full system compromise. The vulnerability stems from insufficient input validation and improper sanitization of file path parameters. Exploitation requires local access but no authentication, meaning any user or process with local system access could leverage this flaw. No public exploits are currently known, and no CVSS score has been assigned yet. However, the combination of information disclosure, SSRF, and command execution makes this a significant threat. The vulnerability is particularly concerning for environments where Local Agent DVR is deployed on critical infrastructure or where local access controls are lax. The lack of patch links indicates that a fix may not yet be available, emphasizing the need for immediate mitigation steps.

For European organizations, the impact of CVE-2025-63408 can be severe. Local Agent DVR is commonly used in video surveillance and monitoring systems, which are critical for physical security in enterprises, government facilities, and public infrastructure. Exploitation could lead to unauthorized access to sensitive video footage or configuration files, violating privacy regulations such as GDPR. SSRF capabilities could allow attackers to pivot within internal networks, accessing otherwise protected systems or services. The ability to execute OS commands elevates the risk to full system compromise, potentially allowing attackers to install malware, disrupt operations, or exfiltrate data. This threat is particularly impactful in sectors like transportation, energy, and public safety, where surveillance systems are integral. The local access requirement limits remote exploitation but does not eliminate risk, especially in environments with shared or poorly controlled access. The absence of known exploits in the wild provides a window for proactive defense, but organizations should act swiftly to mitigate potential damage.

1. Immediately restrict local access to systems running Local Agent DVR to trusted personnel only, enforcing strict access controls and monitoring. 2. Implement application whitelisting and endpoint protection to detect and prevent unauthorized command execution. 3. Monitor system logs and network traffic for unusual activity indicative of SSRF or directory traversal attempts. 4. Segregate surveillance systems from general IT networks to limit lateral movement in case of compromise. 5. Apply patches or updates from the vendor as soon as they become available; maintain close communication with the vendor for release information. 6. Conduct regular security audits and vulnerability scans focusing on Local Agent DVR deployments. 7. Use file integrity monitoring to detect unauthorized changes to critical files. 8. Educate local users about the risks of unauthorized access and enforce strong local authentication mechanisms where possible. 9. Consider temporary disabling or isolating vulnerable instances if patching is delayed. 10. Prepare incident response plans specific to DVR system compromises.
