WordPress TranslatePress is a popular plugin used by website administrators and developers to facilitate the translation and localization of WordPress websites. It is developed by Cozmoslabs and is widely utilized for its ease of use and comprehensive translation capabilities. This plugin is primarily used by content creators, businesses, and developers who need to reach a multilingual audience. TranslatePress integrates seamlessly into WordPress, allowing users to translate text directly from the front end in real time. It supports all WordPress themes and plugins, ensuring that every aspect of a site can be translated. Additionally, it provides features like automatic translations, easy-to-use translation management, and SEO-friendly URL structures.
Cross-Site Scripting (XSS) vulnerabilities allow attackers to inject and execute arbitrary JavaScript code in users' browsers. In the context of the TranslatePress plugin, the vulnerability arises from improper handling of inputs in translation marker processing features. Attackers can exploit this vulnerability without any authentication or privileges, making it a significant security risk. Successful exploitation can lead to the execution of unwanted scripts that may hijack user sessions or facilitate account takeovers. The vulnerability impacts versions of TranslatePress lower than 3.2.6, affecting any site running these versions with the plugin installed. This type of vulnerability is common in web applications and requires careful validation and sanitization of user inputs to mitigate.
The TranslatePress plugin's translation marker processing feature, specifically, is vulnerable to reflected XSS attacks due to inadequate input validation and sanitation. Attackers can craft specific GET requests that inject JavaScript into pages rendered by the plugin. For instance, the endpoint processing translation markers can be tricked into including harmful script payloads within HTML content. The template attempts verifying vulnerability presence by searching for script injection signs in the response body. Moreover, it targets the language switcher feature with specific requests to ensure it finds XSS evidence. The vulnerability does not need user interaction beyond visiting a maliciously-crafted URL, enabling attackers to potentially exploit it at large scale if not fixed promptly.
When this XSS vulnerability is successfully executed, it can have serious consequences for affected sites and users. Potential effects include unauthorized control over user accounts through session capturing or manipulation. Users may be involuntarily redirected to phishing sites or have their personal data accessed without permission. This form of attack can degrade trust in the site as users experience unexpected behaviors or information theft. Additionally, compromised sessions can lead to further exploits or unauthorized actions on behalf of those users. Over time, failure to patch such vulnerabilities can weaken site integrity and expose all users to harmful activities orchestrated via hijacked sessions.
REFERENCES
