Description

This security bulletin contains information about 1 security vulnerability.


1) Dangerous file upload (CVE-ID: CVE-2023-23937)

The vulnerability allows a remote user to bypass implemented security restrictions.

The vulnerability exists due to insufficient validation of the file content-type during file upload when updating user profile. A remote user bypass security check by adding a valid signature (p.e. GIF89) and sending any invalid content-type. This could allow an authenticated user to upload HTML files with JS content that will be executed in the context of the domain.
