CVE-2026-1324 in Operation and Maintenance Management System
Summary
by MITRE • 01/22/2026
A vulnerability was identified in Sangfor Operation and Maintenance Management System up to 3.0.12. Affected by this issue is the function SessionController of the file /isomp-protocol/protocol/session of the component SSH Protocol Handler. The manipulation of the argument keypassword leads to os command injection. It is possible to initiate the attack remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

Analysis

This vulnerability exists within the Sangfor Operation and Maintenance Management System version 3.0.12 and earlier, specifically affecting the SSH Protocol Handler component. The flaw resides in the SessionController function located at /isomp-protocol/protocol/session, where improper input validation allows for arbitrary command execution through manipulation of the keypassword argument. The vulnerability represents a critical security weakness that enables remote exploitation without requiring authentication, making it particularly dangerous for organizations relying on this system for operational management.
The technical implementation of this vulnerability stems from insufficient sanitization of user-supplied input within the keypassword parameter, which is processed directly without proper escaping or validation mechanisms. This allows attackers to inject malicious operating system commands that execute with the privileges of the affected service account. The vulnerability maps directly to CWE-77, known as "Improper Neutralization of Special Elements used in a Command ('Command Injection')," and aligns with ATT&CK technique T1059.001 for Command and Scripting Interpreter. The remote exploitability means that threat actors can leverage this weakness from outside the network perimeter without requiring physical access or prior credentials.
The operational impact of this vulnerability extends beyond simple command execution, as successful exploitation could enable attackers to gain full system control, access sensitive operational data, modify system configurations, or establish persistent backdoors within the network infrastructure. Organizations using Sangfor's Operation and Maintenance Management System may face severe consequences including data breaches, system compromise, and potential lateral movement throughout their network environment. The lack of vendor response to early disclosure attempts exacerbates the risk, leaving affected organizations without official patches or mitigation guidance during an active exploitation period.
Organizations should immediately implement network segmentation to isolate affected systems, disable unnecessary SSH services where possible, and monitor network traffic for suspicious command execution patterns. The most effective immediate mitigation involves patching the system to the latest version where this vulnerability has been addressed. Security teams should also consider implementing intrusion detection systems with signatures for known command injection patterns and establish comprehensive monitoring of system logs for unauthorized command execution attempts. Additionally, organizations should conduct thorough vulnerability assessments of all Sangfor products within their environment and consider temporary workarounds such as disabling the vulnerable SSH protocol handler component until official patches are deployed.
