CVE-2023-2178 Scanner

Aajoda Testimonials is a WordPress plugin that allows website owners to easily display testimonials from customers or clients. It provides features for adding, managing, and customizing testimonials, enhancing the credibility and trustworthiness of websites. This plugin is particularly useful for businesses, online retailers, and service providers looking to showcase positive feedback and experiences shared by their users. It supports various display styles and customization options, making it a versatile tool for web designers and site administrators aiming to improve user engagement and conversion rates.

The Cross-Site Scripting vulnerability in Aajoda Testimonials plugin versions before 2.2.2 stems from insufficient sanitization and escaping of plugin settings. This flaw allows high-privilege users, such as administrators, to inject malicious scripts into web pages, even when the unfiltered_html capability is restricted, as in a multisite setup. Attackers can exploit this vulnerability to perform actions on behalf of users, steal sensitive information, or deface the website, posing a significant security risk to affected websites.

Specifically, the vulnerability is related to the plugin's handling of settings input, where injected scripts can be stored persistently in the database and executed in the browser of any user visiting the affected pages. This issue is due to the lack of proper input validation and output encoding in the plugin's settings management, particularly in fields that are expected to be safe text inputs. The exploitation of this vulnerability requires administrative access, limiting the attack vector to those with high-level privileges or attackers who have compromised an administrator's account.

Exploiting this XSS vulnerability could lead to several adverse effects, including the theft of authentication cookies, session hijacking, phishing attacks directed at users or administrators, and the insertion of malicious content on the site. This can undermine the security and integrity of the website, damage its reputation, and expose users to further attacks. The ability to execute scripts in the context of the site also opens up the possibility for more sophisticated attacks, such as network pivoting or the deployment of web-based malware.
