XWiki is an open-source platform written in Java that is used for developing collaborative and extensible wiki applications. It is utilized by organizations for knowledge management, collaborative workspaces, and dynamic content management, providing a versatile platform for both web and intranet information sharing. Its flexibility and extensibility make it popular for creating content-oriented applications. Managed by a global community, XWiki offers features such as advanced search capabilities, customizable dashboards, and integration with other tools. Designed to cater to a wide range of users, from small businesses to large enterprises, XWiki is prized for its robust set of features that support extensive customization and collaboration.

Cross-Site Scripting (XSS) is a type of vulnerability that allows an attacker to introduce malicious scripts into web pages viewed by other users. This particular XSS vulnerability in XWiki involves the reflection of input data into the response of web pages, enabling the execution of attacker-supplied scripts in the victim's browser. Such exploits can manipulate web content or hijack session tokens, compromising user interactions with the website. This vulnerability is identified in authentication endpoints of XWiki where user inputs can be embedded and executed on the site without proper sanitization. Due to its nature, it poses a risk of session hijacking, defacement, or delivery of malicious content to unsuspecting users.

The technical aspect of this vulnerability relates to a missing or inadequate input validation mechanism in the authenticate endpoint of XWiki. This endpoint may inadvertently reflect user inputs in a way that launches JavaScript execution via HTML attributes or scripts. Vulnerable parameters could be manipulated to deliver JavaScript payloads, exploiting the trust a browser has in the content supplied by XWiki. The vulnerability exemplifies how user inputs can be mistakenly trusted and mishandled, resulting in an attack vector for script execution. An attacker might use this opportunity to craft URLs with embedded JavaScript for phishing or data extraction purposes through cross-site scripting.

If exploited, this vulnerability could allow attackers to execute arbitrary JavaScript in clients’ browsers, potentially leading to theft of credentials, unauthorized actions within the user's session, or dissemination of malware. The impact on the user experience and security may lead to unauthorized disclosure of sensitive data and disruption of services. Organizations relying on XWiki are at risk of damaging their reputation due to unwanted interference or exposure. The vulnerability prioritizes the importance of ensuring that data entered by one user cannot become an attack vector affecting many others. Without remediation, affected systems could facilitate unauthorized actions by malicious entities against users or data integrity.
