Authenticated Arbitrary File Upload in Multiple WSO2 Products via SOAP Admin Service Leading to Remote Code Execution

An arbitrary file upload vulnerability exists in multiple WSO2 products due to improper validation of user input in SOAP admin services. A malicious actor with administrative privileges can upload an arbitrary file to a user-controlled location on the server. By leveraging this vulnerability, an attacker could upload a specially crafted payload, potentially achieving remote code execution (RCE) on the server. Exploitation requires valid admin credentials, limiting its impact to authorized but potentially malicious users.
