CVE-2026-1412
📋 TL;DR
This CVE describes a command injection vulnerability in Sangfor Operation and Maintenance Security Management System. Attackers can execute arbitrary commands remotely via HTTP POST requests to the /fort/audit/get_clip_img endpoint by manipulating the frame/dirno parameter. Organizations using Sangfor O&M Security Management System versions up to 3.0.12 are affected.
💻 Affected Systems
- Sangfor Operation and Maintenance Security Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing attackers to execute arbitrary commands with system privileges, potentially leading to data theft, lateral movement, or complete system takeover.
Likely Case
Remote code execution enabling attackers to install malware, create backdoors, or disrupt system operations.
If Mitigated
Limited impact with proper network segmentation, web application firewalls, and least privilege configurations in place.
🎯 Exploit Status
Exploit details are publicly available on GitHub, making this easily weaponizable. The vulnerability requires only HTTP POST requests with crafted parameters.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Contact Sangfor for official patch information. 2. Monitor vendor security advisories. 3. Upgrade to version beyond 3.0.12 when available.
🔧 Temporary Workarounds
Network Access Control
linuxRestrict access to the vulnerable endpoint using network controls
iptables -A INPUT -p tcp --dport 80 -m string --string '/fort/audit/get_clip_img' --algo bm -j DROP
iptables -A INPUT -p tcp --dport 443 -m string --string '/fort/audit/get_clip_img' --algo bm -j DROP
Web Application Firewall Rules
allBlock malicious requests containing command injection patterns
WAF rule: Block requests to /fort/audit/get_clip_img with suspicious parameters containing shell metacharacters (;, |, &, $, `, etc.)
🧯 If You Can't Patch
- Isolate affected systems in a segmented network zone with strict access controls
- Implement application-level input validation and sanitization for all user-supplied parameters
🔍 How to Verify
Check if Vulnerable:
Check if system responds to POST requests at /fort/audit/get_clip_img with version <= 3.0.12. Test with safe payloads like 'echo test' in frame/dirno parameter.Check Version:
Check system administration interface or configuration files for version information. Command varies by deployment.Verify Fix Applied:
Verify the endpoint no longer executes arbitrary commands when supplied with malicious input. Test with safe command injection test payloads.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /fort/audit/get_clip_img
- System logs showing unexpected command execution
- Web server logs with suspicious parameters containing shell metacharacters
Network Indicators:
- HTTP POST requests to /fort/audit/get_clip_img with unusual parameters
- Outbound connections from the Sangfor system to unexpected destinations
SIEM Query:
source="web_server" AND uri="/fort/audit/get_clip_img" AND (param="frame" OR param="dirno") AND (value="*;*" OR value="*|*" OR value="*`*" OR value="*$(*")
