The Stock Ticker WordPress plugin is a tool used by website owners to display real-time stock ticker information on their WordPress sites. It's designed for financial bloggers, investment advisors, or anyone interested in showing live stock market data. This plugin fetches data from various stock exchanges and presents it in a customizable ticker format, allowing site visitors to stay updated with the latest stock prices and market trends. Its features include customizable appearance, support for multiple stock exchanges, and the ability to display specific stocks or global market indexes.
CVE-2022-45365 discloses a reflected Cross-Site Scripting (XSS) vulnerability found in versions up to and including 3.23.2 of the Stock Ticker WordPress plugin. This vulnerability arises due to insufficient input sanitization and output escaping in the ajax_stockticker_symbol_search_test function. Unauthenticated attackers can exploit this flaw by crafting malicious URLs that, when clicked by a user, execute arbitrary web scripts in the user's browser context.
The vulnerability specifically exists in the way the Stock Ticker plugin handles AJAX requests through the /wp-admin/admin-ajax.php endpoint. An attacker can inject malicious scripts into the 'symbol' and 'endpoint' parameters of a POST request. These scripts are then reflected back in the response from the server and executed in the context of the user's browser session. The attack can lead to unauthorized actions being performed on behalf of the user, data theft, or redirection to malicious websites.
The exploitation of this XSS vulnerability could lead to a range of security issues including session hijacking, phishing attacks, theft of sensitive information, and the spread of malware. Users could be tricked into executing unauthorized actions on the website, potentially compromising their security and privacy, as well as the integrity of the website itself.
