CVE-2023-0334 Scanner Detail

ShortPixel Adaptive Images is a WordPress plugin designed to optimize and serve images in the most efficient size and format, based on the visitor's screen and browser. It significantly improves website loading times and performance, making it a valuable tool for website owners and developers who prioritize user experience and SEO. The plugin dynamically resizes, compresses, and serves images from a global CDN, ensuring images load quickly without compromising quality. It is widely used across various WordPress sites, from personal blogs to large e-commerce platforms, to enhance visual content delivery and site speed.

The Cross-Site Scripting (XSS) vulnerability in versions of ShortPixel Adaptive Images before 3.6.3 arises from the plugin's failure to properly sanitize and escape a parameter before outputting it back into the page. This oversight allows attackers to inject malicious scripts into web pages, which are then executed in the browser of any user viewing the content. This vulnerability specifically targets high privilege users, such as admins, and can lead to unauthorized access, data theft, or manipulation of web page content.

The vulnerability is triggered when the SPAI_VJS parameter in the URL is manipulated to include malicious JavaScript code. Due to insufficient input validation, this script is executed when the page is loaded in a user's browser. This could allow attackers to perform a variety of malicious actions, such as stealing session cookies, redirecting users to phishing sites, or altering page content, all under the guise of the legitimate website.

Exploiting this XSS vulnerability could lead to a range of adverse effects, including theft of sensitive information (such as login credentials and personal data), account takeover, dissemination of malware, defacement of the website, and eroding trust in the website or its administrators. High privilege users, like administrators, are particularly at risk, as attackers can gain access to the backend of the website, allowing for further exploitation and damage.
