PrestaShop XSS can be stored in DB from "add a message form" in order detail page (FO)

Moderate severity GitHub Reviewed Published Jan 2, 2024 in PrestaShop/PrestaShop • Updated Jan 3, 2024

Package

composer prestashop/prestashop (Composer)

Affected versions

< 8.1.3

Patched versions

8.1.3

Description

Impact

The isCleanHtml method is not used on this this form, which makes it possible to store an xss in DB.
The impact is low because the html is not interpreted in BO, thanks to twig's escape mechanism.
In FO, the xss is effective, but only impacts the customer sending it, or the customer session from which it was sent.

Be careful if you have a module fetching these messages from the DB and displaying it without escaping html.

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.
