Possible CSRF token fixation

Moderate severity GitHub Reviewed Published Mar 13, 2023 in PrestaShop/PrestaShop • Updated Mar 13, 2023

Package

composer prestashop/prestashop (Composer)

Affected versions

< 8.0.1

Patched versions

8.0.1

Description

Impact

When authenticating users PrestaShop preserves session attributes. Because this does not clear CSRF tokens upon login, this might enables same-site attackers to bypass the CSRF protection mechanism by performing an attack similar to a session-fixation.

Patches

The problem is fixed in version 8.0.1

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
