EZP-32190: System information tab is accessible via direct link without checking permissions

High
glye published GHSA-w93j-6g2w-mp9v Dec 1, 2020

Package

composer ezsystems/ez-support-tools (Composer)

Affected versions

v2.2.*

Patched versions

v2.2.3

Description

Impact

A user having insufficient permissions is able to access the system information tabs if they type in the direct link (the link is not shown in the menu). The "Setup / System info" policy should be required to access it, but only backend login is currently required. This means any editor can see core system information, including the output from phpinfo(). This affects ezsystems/ez-support-tools v2.2, part of Ibexa DXP v3.2. Older versions are not affected.

Patches

ezsystems/ez-support-tools v2.2.3
