Download route allows filename change

Low
glye published GHSA-946c-f9w6-2c25 Nov 3, 2023

Package

composer ezsystems/ezpublish-kernel (Composer)

Affected versions

v7.5.*

Patched versions

v7.5.31

Description

Impact

The route used for file downloads allows specifying the name of the downloaded file. This is an unintended side effect of the implementation, and means one could construct download URLs with filenames that have no relation to the actual file, which could lead to misunderstandings and confusion, and possibly other harm. As such it is a low severity vulnerability. It affects all supported versions of Ibexa DXP and eZ Platform, in installations where downloadable files exist.

Patches

The issue is fixed in all supported versions of ezsystems/ezpublish-kernel, see "Patched versions".
An advisory is also published for ezsystems/ezplatform-kernel and ibexa/core, please see those repositories.
Commit: 142152f

Workarounds

None, other than blocking all downloads.
