CVE-2026-1414 is a command injection vulnerability identified in the Sangfor Operation and Maintenance Security Management System, affecting all versions up to 3.0.12. The vulnerability resides in the getInformation function, specifically in the HTTP POST request handler at the endpoint /equipment/get_Information. The issue arises due to improper sanitization of the fortEquipmentIp parameter, which an attacker can manipulate to inject arbitrary system commands. This flaw allows remote attackers to execute commands on the underlying operating system without requiring authentication or user interaction, significantly increasing the attack surface. The vulnerability has been publicly disclosed, though no active exploitation has been reported yet. The CVSS 4.0 base score of 5.3 indicates a medium severity, considering the vulnerability's network attack vector, low attack complexity, no privileges required, and no user interaction needed. The impact on confidentiality, integrity, and availability is limited but present, as successful exploitation could allow attackers to execute commands that may lead to data leakage, system compromise, or service disruption. The lack of available patches at the time of disclosure necessitates immediate mitigation through network-level controls and monitoring. Sangfor's Operation and Maintenance Security Management System is typically used for managing network devices and security infrastructure, making this vulnerability particularly critical in environments where this product is deployed for operational oversight and security management.

For European organizations, exploitation of this vulnerability could lead to unauthorized remote command execution on critical network management systems, potentially resulting in data breaches, disruption of network operations, or further lateral movement within the network. Given that the affected product is used for operation and maintenance security management, attackers gaining control could manipulate device configurations, disable security controls, or exfiltrate sensitive operational data. This could impact confidentiality by exposing sensitive network information, integrity by altering configurations or logs, and availability by disrupting management functions. The medium severity score reflects a moderate risk; however, the absence of authentication and user interaction requirements increases the likelihood of exploitation. Organizations in sectors such as telecommunications, critical infrastructure, and large enterprises relying on Sangfor products for network management are at heightened risk. The public disclosure of the vulnerability increases the urgency for European entities to assess exposure and implement mitigations promptly to prevent potential attacks.

1. Immediately restrict network access to the Sangfor Operation and Maintenance Security Management System interface, limiting it to trusted administrative networks or VPNs. 2. Implement strict input validation and filtering at the application or web server level to detect and block malicious payloads targeting the fortEquipmentIp parameter. 3. Monitor logs and network traffic for unusual POST requests to /equipment/get_Information, especially those containing suspicious command injection patterns. 4. Deploy web application firewalls (WAFs) with custom rules to detect and block command injection attempts targeting this endpoint. 5. Engage with Sangfor support or vendor channels to obtain and apply official patches or updates as soon as they become available. 6. Conduct regular security assessments and penetration tests focusing on management interfaces to identify similar injection vulnerabilities. 7. Educate network and security teams about this vulnerability to ensure rapid detection and response to potential exploitation attempts. 8. Consider network segmentation to isolate management systems from general user networks, reducing the attack surface.
