CVE-2019-17231 Scanner

The WordPress OneTone theme is widely utilized by website developers and administrators for creating visually appealing and customizable websites with ease. Developed by MageeWP, it caters to users who prefer a blend of design elegance and functionality. As a popular theme, it is used extensively by businesses and individuals seeking a professional online presence. Its features allow users to implement quick design changes and interactive elements without in-depth coding knowledge. The theme supports integration with various WordPress plugins, extending its capabilities further. Overall, OneTone is a robust theme choice for WordPress users aiming for a dynamic interface.

The Cross-Site Scripting (XSS) vulnerability found in the OneTone theme can allow attackers to inject malicious scripts into web pages that are viewed by other users. Such vulnerabilities pose significant risks as they can lead to data theft or manipulation without the knowledge or consent of the users. In the context of the OneTone theme, multiple stored XSS issues have been identified, especially in the file includes/theme-functions.php. Attackers exploit these weaknesses to hijack cookies, which can lead to unauthorized access and data breaches. XSS vulnerabilities undermine the security of websites by allowing potentially malicious interactions. Addressing these vulnerabilities is crucial to maintain the integrity and trustworthiness of a website.

The technical details of the vulnerability reveal that it occurs within the OneTone theme's includes/theme-functions.php file. Specifically, the vulnerability is exploited through improper handling of user input which is not sanitized correctly, allowing JavaScript code injection. Attackers typically target the 'onetone_options_import' action within WordPress's admin-ajax.php interface. By sending a crafted payload that includes a malicious script, attackers can successfully inject XSS content. Key vulnerable parameters include those handling input data capable of rendering directly in the frontend. This stored XSS remains persistent, affecting any users who visit the compromised site across all sessions. It's essential for developers to implement better validation and sanitization processes to prevent such exploitation.

Exploiting this XSS vulnerability in the OneTone theme could result in several severe consequences. Malicious users may hijack session cookies, leading to unauthorized actions performed on behalf of logged-in users. It could potentially facilitate phishing attacks by redirecting users to malicious pages or displaying deceptive content. Other effects may include defacement of the affected website, unauthorized data changes, or spreading further malware through injected scripts. The reputation damage to businesses using compromised websites can be significant, eroding user trust and potentially impacting revenue. Addressing the vulnerability promptly helps in safeguarding user interactions and maintaining site security.
