CVE-2025-45854 Overview
CVE-2025-45854 is a critical remote code execution vulnerability in JEHC-BPM 2.0.1, a business process management system. The vulnerability exists in the /server/executeExec endpoint, which allows unauthenticated attackers to execute arbitrary code on the target system through the execParams parameter. This flaw enables complete system compromise without requiring any user interaction or authentication.
Critical Impact
Unauthenticated remote code execution allowing complete system takeover with network-level access

Technical Details for CVE-2025-45854
Vulnerability Analysis
This vulnerability is classified under CWE-862 (Missing Authorization), indicating that the /server/executeExec endpoint lacks proper access control mechanisms. The endpoint is designed to execute server-side operations but fails to verify whether the requesting user has appropriate privileges to perform such actions. This architectural weakness allows any network-accessible attacker to leverage the execParams parameter to inject and execute arbitrary commands on the underlying server.
The vulnerability affects the core execution functionality of the BPM system, where user-supplied input through execParams is processed without adequate sanitization or authorization checks. This creates a direct pathway for attackers to achieve full system compromise.
Root Cause
The root cause of this vulnerability is missing authorization controls on the /server/executeExec endpoint. The application fails to implement proper authentication and authorization checks before processing the execParams parameter, which is subsequently used in command execution operations. This allows unauthenticated users to supply arbitrary commands that are executed with the privileges of the application server process.
Attack Vector
The attack is conducted over the network and requires no authentication or user interaction. An attacker can craft malicious HTTP requests to the /server/executeExec endpoint, passing specially crafted values in the execParams parameter. These values are then interpreted and executed as system commands, granting the attacker the ability to run arbitrary code, install malware, exfiltrate data, or pivot to other systems within the network.
The vulnerability is exploited by sending a crafted HTTP POST request to the vulnerable endpoint containing malicious command payloads within the execParams parameter. Technical details and proof-of-concept information can be found in the GitHub Gist Code Snippet referenced in the security advisory.
Detection Methods for CVE-2025-45854
Indicators of Compromise
- Unusual HTTP POST requests to /server/executeExec endpoint from external or unauthorized sources
- Unexpected process spawning originating from the JEHC-BPM application server
- Suspicious command execution patterns in system logs correlating with web server access logs
- Anomalous network connections from the BPM server to external IP addresses
Detection Strategies
- Monitor web application logs for requests targeting the /server/executeExec endpoint
- Implement intrusion detection rules to flag requests containing suspicious execParams values
- Deploy web application firewalls (WAF) with rules to detect command injection patterns in HTTP parameters
- Enable process monitoring on JEHC-BPM servers to detect unauthorized command execution
Monitoring Recommendations
- Configure SIEM alerts for high-frequency or anomalous access to the /server/executeExec endpoint
- Review and correlate web server access logs with system process execution logs
- Implement network segmentation monitoring to detect lateral movement following potential exploitation
How to Mitigate CVE-2025-45854
Immediate Actions Required
- Restrict network access to the /server/executeExec endpoint immediately using firewall rules
- Implement strong authentication and authorization controls for all administrative endpoints
- Review and audit server logs for any signs of prior exploitation
- Consider taking JEHC-BPM offline until proper mitigations are in place
Patch Information
As of the last NVD update on August 26, 2025, no official vendor patch has been publicly documented. Organizations should monitor the Gitee Project Repository for security updates and patches from the vendor. The Web Archive Gist Revisions provides additional technical context on this vulnerability.
Workarounds
- Block external access to the /server/executeExec endpoint at the network perimeter
- Implement IP whitelisting to allow only trusted administrative hosts to access the endpoint
- Deploy a reverse proxy or WAF to filter and sanitize requests before they reach the application
# Example firewall rule to block external access to vulnerable endpoint
iptables -A INPUT -p tcp --dport 80 -m string --string "/server/executeExec" --algo bm -j DROP
iptables -A INPUT -p tcp --dport 443 -m string --string "/server/executeExec" --algo bm -j DROP
