CVE-2025-45854
📋 TL;DR
CVE-2025-45854 is a critical remote code execution vulnerability in JEHC-BPM 2.0.1 that allows attackers to execute arbitrary commands via the /server/executeExec endpoint. This affects all organizations running vulnerable versions of JEHC-BPM workflow management software, potentially giving attackers complete control over affected systems.
💻 Affected Systems
- JEHC-BPM
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to install malware, steal sensitive data, pivot to other systems, and maintain persistent access.
Likely Case
Attackers gain shell access to the server, deploy ransomware or cryptominers, and exfiltrate database contents and configuration files.
If Mitigated
If proper network segmentation and least privilege are implemented, impact may be limited to the application server only.
🎯 Exploit Status
Public proof-of-concept code is available showing simple HTTP POST requests to /server/executeExec with execParams parameter containing arbitrary commands.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Check the Gitee repository for updates or consider alternative BPM solutions.
🔧 Temporary Workarounds
Block vulnerable endpoint
allAdd WAF rules or network filtering to block access to /server/executeExec endpoint
# Example nginx location block:
location /server/executeExec { deny all; }
# Example Apache .htaccess:
<Location "/server/executeExec">
Order deny,allow
Deny from all
</Location>
Input validation filter
allAdd application-level input validation to reject execParams containing shell metacharacters
# Java example for input validation:
if (execParams != null && execParams.matches(".*[;&|`$(){}<>\\[\\]\\"'].*")) {
throw new SecurityException("Invalid parameters");
}
🧯 If You Can't Patch
- Immediately isolate affected systems from internet and restrict network access to authorized users only
- Implement strict monitoring and alerting for any access to /server/executeExec endpoint
🔍 How to Verify
Check if Vulnerable:
Send HTTP POST request to http://target:port/server/executeExec with execParams parameter containing harmless command like 'whoami' or 'echo test'Check Version:
Check application version in web interface or configuration files. Look for version 2.0.1 in deployment artifacts.Verify Fix Applied:
Test that the same request now returns error or is blocked, and verify no command execution occurs📡 Detection & Monitoring
Log Indicators:
- HTTP POST requests to /server/executeExec
- Unusual process execution from web server user
- Shell commands in web server logs
Network Indicators:
- HTTP traffic to /server/executeExec endpoint with execParams parameter
- Outbound connections from web server to unusual destinations
SIEM Query:
source="web_server" AND (uri="/server/executeExec" OR message="execParams")
