Summary

An arbitrary file upload vulnerability exists in multiple WSO2 products due to improper validation of user-supplied filenames in the BPEL uploader SOAP service endpoint. A malicious actor with administrative privileges can upload arbitrary files to a user-controlled location on the server.

By leveraging this vulnerability, an attacker can upload a specially crafted payload and achieve remote code execution (RCE), potentially compromising the server and its data.
