SB2020012747 - Improper access control in Sylius

Description

This security bulletin contains information about 1 vulnerability.

1) Improper access control (CVE-ID: CVE-2020-5218)

CWE-ID: CWE-284 - Improper Access Control

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to switch channels in production environments.

The vulnerability exists due to improper access control in the channel switching feature when processing the _channel_code GET parameter. A remote attacker can supply a crafted _channel_code parameter to switch channels in production environments.

The issue occurs when sylius_channel.debug is not explicitly set, causing the debug feature to remain enabled because the default %kernel.debug% value is not resolved and is cast to boolean.

Remediation

Install update from vendor's website.
