WSO2 Identity Server: Unrestricted Upload of File with Dangerous Type
CVE-2025-3125 is a high-severity unrestricted upload of file with dangerous type vulnerability in WSO2 Identity Server from WSO2, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists versions 5.10.0.360, 5.11.0.399, 6.0.0.235 as the first without the flaw, so updating WSO2 Identity Server to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.91% chance of exploitation within 30 days, higher than 61% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update WSO2 Identity Server to 5.10.0.360 or 5.11.0.399 or 6.0.0.235 or 6.1.0.230, whichever matches your release line, or a later version.
- Update WSO2 Enterprise Integrator to 6.6.0.217 or a later version.
- Update WSO2 Open Banking IAM to 2.0.0.402 or a later version.
- Read the advisory on security.docs.wso2.com for workarounds and exact fixed builds.

Official 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.

The underlying weakness: Unrestricted Upload of File with Dangerous Type
The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
How developers prevent this class of flaw
- Generate a new, unique filename for an uploaded file instead of using the user-supplied filename, so that no external input is used at all.
- When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
- Consider storing the uploaded files outside of the web document root entirely. Then, use other mechanisms to deliver the files dynamically.
