CVE-2025-3125

MEDIUM
Published Nov 5, 2025 Modified Dec 4, 2025 CWE-434

Description

An arbitrary file upload vulnerability exists in multiple WSO2 products due to improper input validation in the CarbonAppUploader admin service endpoint. An authenticated attacker with appropriate privileges can upload a malicious file to a user-controlled location on the server, potentially leading to remote code execution (RCE). This functionality is restricted by default to admin users; therefore, successful exploitation requires valid credentials with administrative permissions.
