CVE-2026-1324
📋 TL;DR
This CVE describes a remote command injection vulnerability in Sangfor Operation and Maintenance Management System's SSH Protocol Handler. Attackers can execute arbitrary operating system commands by manipulating the keypassword argument, potentially leading to complete system compromise. Organizations using Sangfor Operation and Maintenance Management System versions up to 3.0.12 are affected.
💻 Affected Systems
- Sangfor Operation and Maintenance Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining root/administrator privileges, data exfiltration, ransomware deployment, and persistent backdoor installation.
Likely Case
Unauthorized command execution leading to data theft, system manipulation, and lateral movement within the network.
If Mitigated
Limited impact due to network segmentation, minimal privileges, and proper monitoring detecting exploitation attempts.
🎯 Exploit Status
Exploit details are publicly available on GitHub, making this easily weaponizable. Remote exploitation without authentication is possible.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Vendor did not respond to disclosure. Consider workarounds or alternative solutions.
🔧 Temporary Workarounds
Disable SSH Protocol Handler
allTemporarily disable the vulnerable SSH Protocol Handler component if not required for operations.
Check Sangfor documentation for component disable procedures
Network Access Control
linuxRestrict network access to the Sangfor system using firewall rules to only allow trusted IP addresses.
iptables -A INPUT -p tcp --dport [Sangfor_port] -s [trusted_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [Sangfor_port] -j DROP
🧯 If You Can't Patch
- Isolate the Sangfor system in a separate network segment with strict firewall rules.
- Implement application-level monitoring and alerting for suspicious command execution patterns.
🔍 How to Verify
Check if Vulnerable:
Check the Sangfor Operation and Maintenance Management System version. If version is 3.0.12 or lower, it is vulnerable.Check Version:
Check Sangfor system administration interface or configuration files for version information.Verify Fix Applied:
Since no official patch exists, verify workarounds by testing SSH Protocol Handler accessibility and monitoring for exploitation attempts.📡 Detection & Monitoring
