CVE-2025-54125 Scanner

XWiki is a versatile open-source wiki platform used by organizations and individuals to manage documentation and collaborate on projects. Designed to facilitate knowledge management, XWiki allows users to create, edit, and share content in a structured manner. It is commonly deployed in corporate environments for internal documentation, as well as in educational settings for collaborative learning. With its extensive customization possibilities through extensions and plugins, XWiki meets diverse needs ranging from simple wiki pages to complex content management systems. Users benefit from its robust search capabilities and permissions management, which foster efficient information sharing. However, security vulnerabilities can arise, affecting the confidentiality and integrity of the platform's data.

The Information Disclosure vulnerability in XWiki allows unauthorized access to sensitive information through the XML view functionality. This vulnerability is particularly concerning as it can expose information like passwords and email addresses stored in fields users may not recognize as sensitive. Attackers can exploit this by accessing user profiles with the 'xml.vm' template, bypassing protections usually afforded to such data. The vulnerability is serious because it requires no prior authentication, increasing the risk of data exposure. Information leakage could lead to unauthorized access and exploitation of other vulnerabilities, undermining user trust and system integrity. Addressing this vulnerability is critical to maintaining security and privacy in XWiki implementations.

Technical details of this vulnerability involve accessing specific URL patterns in XWiki instances. The affected endpoint is '/bin/view/XWiki/{{username}}?xpage=xml', where attackers can manipulate the username parameter to extract data. The XML view functionality mishandles certain custom fields, inadvertently exposing sensitive data embedded in user profiles. Successful exploitation depends on the matchers capturing elements like '', '', '', and '' in the HTTP response body. The mechanism primarily targets the XML content type, rendering it vulnerable if not adequately secured. Potential culprits must ensure requests result in a 200 status code and contain expected XML structures identifiable through HTTP response parsing.

If exploited, this Information Disclosure vulnerability could have severe repercussions, including unauthorized data access and breaches of privacy. Attackers can gain insights into sensitive information, compromising the confidentiality of user profiles and potentially leading to identity theft. Such breaches may further enable more complex attacks, leveraging disclosed data to manipulate other system functionalities or execute phishing schemes. Organizations risk regulatory penalties if personal data protection measures are found lacking. Beyond tangible security risks, exploited vulnerabilities can erode user trust, harm reputation, and result in financial losses, emphasizing the need for immediate remediation.
