PATCH & WORKAROUND1. Official Patch & Version Upgrade Commands
No official patch is currently available as the vendor did not respond to the vulnerability disclosure. Organizations must rely on strict access control and temporary workarounds to mitigate the risk.
2. Temporary Workaround & Hardening Configuration
Block access to the vulnerable password recovery endpoint using an Nginx reverse proxy or a Web Application Firewall (WAF).
# Block access to the vulnerable endpoint in Nginx configuration
server {
listen 443 ssl;
server_name bastion.local;
# Block the weak password recovery endpoint
location /fort/login/edit_pwd_mall {
deny all;
return 403;
}
}3. Log Audit & IoC Verification Commands
Administrators can scan web server access logs to identify potential exploitation attempts targeting the vulnerable endpoint.
# Scan access logs for requests targeting the vulnerable endpoint

Technical Root Cause & Exploitation Mechanics
1. Vulnerability Overview & Root Cause
A critical security flaw (CVE-2026-1325) has been identified in the Sangfor Operation and Maintenance Security Management System. The root cause lies within the edit_pwd_mall function of the /fort/login/edit_pwd_mall file. Due to insufficient validation of the flag parameter during password recovery requests, the system is susceptible to a weak password recovery mechanism (CWE-640), allowing unauthorized password modifications.
2. Exploitation Mechanics & Attack Scenario
An unauthenticated remote attacker can exploit this vulnerability by sending a crafted HTTP request to the /fort/login/edit_pwd_mall endpoint. By manipulating the flag parameter, the attacker can bypass the authentication checks of the password recovery workflow. Since public exploits are available, attackers can easily reset user or administrator passwords and gain unauthorized access to the management console.
3. Infrastructure & Business Impact
As a bastion host system designed to secure and manage enterprise infrastructure, any compromise of this platform has catastrophic consequences. Attackers gaining administrative access can pivot to internal servers, databases, and critical network assets, leading to full infrastructure compromise, data exfiltration, and potential ransomware deployment.
Official Vendor Advisories & References
A security flaw has been discovered in Sangfor Operation and Maintenance Security Management System up to 3.0.12. This affects the function edit_pwd_mall of the file /fort/login/edit_pwd_mall. The manipulation of the argument flag results in weak password recovery. It is possible to launch the attack remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
