Horizon Alert
Summary of the vulnerability and why it matters
This advisory highlights a critical vulnerability in WELLTEND TECHNOLOGY's BPMFlowWebkit, which allows unauthenticated attackers to upload and execute malicious code. This could potentially lead to unauthorized control of the server. The main concern is confirming if this specific technology is in use within our environment.
- Unauthenticated file upload allows server code execution.
- Confirms if this web technology is in use.
- Assess relevance and exposure to our systems.
Attack Path
How an attacker could exploit the issue
Attackers can exploit this vulnerability by uploading a malicious file through the BPMFlowWebkit application. Since no authentication is required, an unauthenticated remote attacker can leverage this exposure to upload a web shell. Successful exploitation allows for arbitrary code execution on the server.
- No authentication needed for access.
- Upload a web shell backdoor.
- Achieve arbitrary code execution.
Live Threat
Current exploitation, exposure, and threat context

- Server code execution.
- Remote file upload.
- Service compromise.
Operational Fix
Recommended remediation, mitigation, and detection steps
The Arbitrary File Upload vulnerability in BPMFlowWebkit requires immediate attention from teams managing web applications and the underlying infrastructure. The first step is to identify all instances of BPMFlowWebkit, determine their exposure and criticality, and assign ownership for remediation planning.
- Identify and confirm BPMFlowWebkit instances.
- Verify exposure and business criticality.
- Plan remediation based on identified risk.
