CVE-2023-32068 Scanner

The XWiki Platform is a widely-used open-source application designed for creating collaborative environments where users can organize and share information effectively. It is employed by organizations for knowledge management, team collaboration, and project management. The platform is favored for its extensibility and robust feature set which include advanced authoring tools, powerful integration capabilities, and strong support for customization. XWiki is utilized by both large enterprises and small communities to foster collaboration while maintaining high content integrity and organization. Users of XWiki appreciate its flexibility and ability to adapt to numerous business scenarios, ranging from internal documentation to external user engagement. The platform's active community and continuous development ensure a steady flow of new features and security updates.

The detected vulnerability in XWiki is identified as an Open Redirect issue, which arises from the improper validation of the xredirect parameter. Open Redirect vulnerabilities can be exploited to redirect users from a legitimate website to a malicious one without their knowledge. This vulnerability, therefore, poses a significant risk as it can undermine user trust and lead to phishing attacks where attackers mimic trusted sites to steal sensitive information. Exploitation of this vulnerability requires the attacker to craft a malicious URL that when clicked by a user, leads them onto a different, potentially harmful, website. Addressing this vulnerability involves ensuring the site redirects are regulated and only allow safe, predefined destinations. This attack vector can be particularly damaging if not addressed promptly, given the user's trust relationship with the original site.

From a technical perspective, the vulnerability hinges on the misuse of parameters used during the redirection process, specifically the xredirect parameter. When a user is supposed to be redirected to a different site location, malicious actors can manipulate these parameters to alter the intended redirect path. The prevention of such threats involves rigorous checking and sanitization of input data, especially those associated with redirect actions. The endpoint at risk is found in the login module, particularly at the URL '/bin/login/XWiki/XWikiLogin', where any unsanitized user input can manipulate the redirect target. Given its potential impact, developers need to implement a validation mechanism that scrutinizes the redirect destinations.

If exploited, an open redirect vulnerability in XWiki could lead to various security challenges including phishing scams and malicious redirection of legitimate traffic. Users unsuspectingly redirected to a nefarious site might expose their login credentials or sensitive personal information under the assumption of being on a trusted domain. Additionally, this can damage the reputation of the organization using XWiki, as users might lose trust knowing their interactions can be misappropriated by third parties. Organizations could face heightened scrutiny and potential financial damages if such vulnerabilities are exploited, particularly if customer data becomes compromised. It is vital for organizations to address these vulnerabilities promptly to maintain secure and trusted online environments for their users.
