CVE-2025-15502
📋 TL;DR
This CVE describes a remote command injection vulnerability in Sangfor Operation and Maintenance Management System. Attackers can execute arbitrary operating system commands by manipulating the Hostname parameter in the SessionController function. Systems running versions up to 3.0.8 are affected.
💻 Affected Systems
- Sangfor Operation and Maintenance 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, ransomware deployment, or complete system takeover.
Likely Case
Attackers gain shell access to the server, install backdoors, pivot to internal networks, and exfiltrate sensitive data.
If Mitigated
Exploitation attempts are blocked by network segmentation, WAF rules, or input validation controls, limiting impact to isolated segments.
🎯 Exploit Status
Public exploit code exists and the vulnerability requires no authentication. Attackers can easily weaponize this for mass exploitation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Vendor has not responded to disclosure. Consider workarounds or alternative solutions.
🔧 Temporary Workarounds
Network Access Control
allRestrict access to the vulnerable endpoint using firewall rules or network segmentation
WAF Rule Implementation
allDeploy web application firewall rules to block command injection patterns in Hostname parameter
🧯 If You Can't Patch
- Isolate the affected system from critical networks and internet access
- Implement strict input validation and sanitization for the Hostname parameter
🔍 How to Verify
Check if Vulnerable:
Check if system is running Sangfor Operation and Maintenance Management System version 3.0.8 or earlier. Review access logs for suspicious requests to /isomp-protocol/protocol/session with unusual Hostname parameters.Check Version:
Check application interface or configuration files for version information. No standard command available.Verify Fix Applied:
Test with safe command injection payloads to verify input validation is working. Monitor for any successful exploitation attempts.📡 Detection & Monitoring
Log Indicators:
- Unusual command strings in Hostname parameter
- Multiple failed login attempts followed by exploitation attempts
- Suspicious process execution from web server context
Network Indicators:
- Unusual outbound connections from the server
- Traffic to known malicious IPs or domains
- Unexpected port scanning from the server
SIEM Query:
source="web_logs" AND uri="/isomp-protocol/protocol/session" AND (Hostname CONTAINS "|" OR Hostname CONTAINS ";" OR Hostname CONTAINS "$" OR Hostname CONTAINS "`")
