CVE-2026-1412 is a command injection vulnerability identified in Sangfor's Operation and Maintenance Security Management System, specifically affecting versions 3.0.0 through 3.0.12. The vulnerability resides in the HTTP POST request handler component, particularly in the /fort/audit/get_clip_img endpoint. An attacker can manipulate the frame/dirno parameter in the POST request to inject arbitrary operating system commands. This injection occurs because the input is not properly sanitized or validated before being passed to system-level command execution functions. The vulnerability can be exploited remotely without requiring any authentication or user interaction, making it highly accessible to attackers. The CVSS v4.0 base score is 6.9, reflecting a medium severity level due to the network attack vector, low complexity, and no privileges or user interaction needed. The impact includes potential unauthorized command execution, leading to data breaches, system compromise, or service disruption. Although no known exploits are currently active in the wild, the public disclosure of the exploit details increases the risk of exploitation. The lack of available patches at the time of reporting necessitates immediate mitigation efforts by affected organizations.

For European organizations, this vulnerability could lead to unauthorized remote command execution on critical security management infrastructure, potentially compromising the confidentiality, integrity, and availability of network operations. Attackers exploiting this flaw could gain control over the affected system, manipulate monitoring data, disable security controls, or pivot to other internal systems. This is particularly concerning for sectors relying on Sangfor's management system for operational security, such as telecommunications, finance, and government agencies. The disruption or compromise of these systems could result in significant operational downtime, data loss, regulatory non-compliance, and reputational damage. Given the remote and unauthenticated nature of the exploit, the threat landscape is broad, increasing the urgency for European entities to address this vulnerability promptly.

1. Immediate mitigation should include restricting network access to the affected /fort/audit/get_clip_img endpoint by implementing firewall rules or network segmentation to limit exposure to trusted sources only. 2. Monitor network traffic and logs for unusual POST requests targeting the frame/dirno parameter to detect potential exploitation attempts. 3. Apply input validation and sanitization at the application layer if possible, to prevent malicious command injection. 4. Engage with Sangfor support or vendor channels to obtain patches or official remediation guidance as soon as they become available. 5. Employ intrusion detection/prevention systems (IDS/IPS) with updated signatures to detect attempts exploiting this vulnerability. 6. Conduct thorough security audits and penetration testing focusing on this endpoint to identify any signs of compromise. 7. Develop and test incident response plans specific to this vulnerability to ensure rapid containment and recovery if exploited.
