PrestaShop ps_contactinfo Module Cross-Site Scripting Vulnerability

A cross-site scripting (XSS) vulnerability has been identified in the PrestaShop ps_contactinfo module, specifically in versions through 3.3.2. This vulnerability arises from the module's use of the 'nofilter' tag in templates, which can be exploited to execute stored XSS payloads. However, it is important to note that this issue cannot be triggered in a fresh installation of PrestaShop; it only affects shops that have been compromised by certain third-party modules, such as those vulnerable to SQL injection. In such cases, ps_contactinfo may inadvertently execute a stored XSS in formatted objects.

Impact

Exploitation of this vulnerability allows for cross-site scripting, where an attacker can inject malicious scripts that are executed in the context of the user's browser.

Remediation

Users are advised to update the ps_contactinfo module to version 3.3.3 or later, and to ensure that all other modules are maintained and up to date.
