CVE-2026-1412 identifies a command injection vulnerability in the Sangfor 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 for the /fort/audit/get_clip_img endpoint, where the frame/dirno parameter is not properly sanitized before being used in system commands. This improper input validation allows an attacker to inject arbitrary commands that the system executes with the privileges of the affected service. The vulnerability is remotely exploitable without any authentication or user interaction, increasing the attack surface significantly. The CVSS v4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known exploits are currently observed in the wild, the public disclosure of the exploit code increases the risk of exploitation. The affected product is used for security management and operation and maintenance tasks, making it a critical component in enterprise and infrastructure environments. The lack of available patches at the time of disclosure necessitates immediate mitigation efforts to reduce risk.

Successful exploitation of this vulnerability can allow attackers to execute arbitrary commands on the affected system remotely, potentially leading to unauthorized access, data leakage, or disruption of services. Given the product’s role in security management and operational maintenance, compromise could enable attackers to manipulate security configurations, disable protections, or pivot within the network. The partial impact on confidentiality, integrity, and availability means sensitive operational data could be exposed or altered, and system availability could be degraded or interrupted. Organizations relying on this system for critical infrastructure or security operations face increased risk of operational disruption and potential regulatory or compliance consequences. The medium CVSS score reflects the balance between ease of exploitation and the scope of impact, but the absence of authentication requirements elevates the threat level. If exploited in targeted attacks, this vulnerability could facilitate lateral movement or persistent footholds within networks.

1. Immediately apply any available patches or updates from Sangfor once released to address this vulnerability. 2. If patches are not yet available, implement strict network-level access controls to restrict access to the /fort/audit/get_clip_img endpoint only to trusted management networks or IP addresses. 3. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting the frame/dirno parameter. 4. Conduct thorough input validation and sanitization on all user-supplied parameters if custom integrations or proxies are used. 5. Monitor logs for unusual or unauthorized commands executed on the system, focusing on the affected endpoint. 6. Segment the network to isolate the Sangfor management system from critical production environments to limit potential lateral movement. 7. Educate security teams to recognize signs of exploitation attempts and prepare incident response plans specific to this vulnerability. 8. Regularly audit and review permissions and configurations of the affected system to minimize the attack surface.
