## What is CVE-2024-39318?

CVE-2024-39318 is a medium-severity cross-site scripting vulnerability in ibexa admin-ui, published on 31 Jul 2024. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

The Ibexa Admin UI Bundle contains all the necessary parts to run the Ibexa DXP Back Office interface. The file upload widget is vulnerable to XSS payloads in filenames. Access permission to upload files is required. As such, in most cases only authenticated editors and administrators will have the required permission. It is not persistent, i.e. the payload is only executed during the upload. In effect, an attacker will have to trick an editor/administrator into uploading a strangely named file.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)
