CVE-2026-1413
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was found in Sangfor Operation and Maintenance Security Management System up to 3.0.12. This affects the function portValidate of the file /fort/ip_and_port/port_validate of the component HTTP POST Request Handler. Performing a manipulation of the argument port results in command injection. The attack can be initiated remotely. The exploit has been made public and could be used.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA command injection vulnerability exists in Sangfor Operation and Maintenance Security Management System (up to v3.0.12) within the HTTP POST Request Handler. The portValidate function in /fort/ip_and_port/port_validate fails to properly sanitize the port argument, allowing remote unauthenticated attackers to inject and execute arbitrary OS commands by manipulating the POST request.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Sangfor product and versionAccess the system's admin interface or check system files for the Sangfor Operation and Maintenance Security Management System version. This is typically found in the about page, system info, or configuration files within the installation directory.Affected if The installed version is 3.0.12 or lower.
-
Locate the vulnerable port_validate endpointCheck if the endpoint /fort/ip_and_port/port_validate exists on the web server. This can be done by attempting to access it via HTTP/HTTPS or reviewing the web application's file structure.Affected if The endpoint /fort/ip_and_port/port_validate is present and accessible on the system.
-
Verify HTTP POST requests are accepted on the vulnerable endpointSend a test HTTP POST request to /fort/ip_and_port/port_validate with a crafted port parameter. Observe if the application processes the parameter without sanitization.Affected if The endpoint accepts POST requests and processes the port parameter without proper input validation.
-
Check network accessibility of the vulnerable serviceDetermine if the web interface is exposed to untrusted networks by reviewing firewall rules, network configurations, or by performing a port scan to identify exposed HTTP/HTTPS ports.Affected if The Sangfor management interface is accessible from untrusted networks without proper access controls.
The system is affected if it runs Sangfor Operation and Maintenance Security Management System version 3.0.12 or lower AND the /fort/ip_and_port/port_validate endpoint is accessible, allowing unauthenticated command injection via the port parameter in POST requests.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImmediately restrict network exposure of the affected system, implement WAF rules to block malicious port parameter values, and apply vendor patch if available. Consider disabling the vulnerable endpoint or upgrading to a patched version.
