XWiki is a generic wiki platform offering runtime services for applications built on it. It is commonly used by organizations and individuals to create collaborative working environments and documentation sites. XWiki supports the creation of wikis and web applications and can be extended with extensions and custom development. The software is widely adopted for creating knowledge bases and intranets due to its rich feature set and scalability. XWiki allows seamless integration with other tools, enhancing productivity in collaborative environments. It is especially popular for use cases requiring custom applications and a user-friendly interface.
The Cross-Site Scripting (XSS) vulnerability involves the injection of malicious scripts into web pages viewed by other users. This vulnerability can allow attackers to execute arbitrary javascript code in the context of the user's browser session. Specifically, in XWiki, an attacker can exploit the DeleteApplication page to perform a XSS attack. The weakness arises in scenarios where URL parameters are improperly sanitized, enabling the attacker to inject scripts. This could lead to unauthorized actions or data leakage if sensitive information is accessed via the script. Such vulnerabilities pose significant security risks, allowing unauthorized control over user interactions.
The technical aspect of this vulnerability pertains to the 'DeleteApplication' page within the XWiki platform, where URL parameters can be modified. Using a crafted URL, such as the one ending in 'xredirect=javascript:alert(document.domain)', an attacker is able to inject XSS payloads. The vulnerability affects versions starting from 6.2-milestone-1, exposing the application to potential exploitation. The affected parameters are not correctly sanitized for script content, leading to the possibility of executing arbitrary javascript in the user's context. The vulnerability exists due to insufficient filtering or encoding of parameters that are reflected in HTML response to the user. Effective sanitation and validation of input data are key measures to mitigate such vulnerabilities.
Exploitation of this vulnerability can lead to several detrimental outcomes. Malicious scripts executed via XSS can steal user cookies, session tokens, or other sensitive information. It may facilitate unauthorized actions on behalf of the user, leading to potential hijacking of user sessions. In certain cases, it can create persistent payloads that affect numerous users, leading to broader security compromise. Moreover, the affected system's integrity and user trust are significantly undermined by such attacks. Persistent exploitation may disrupt normal service operations and require extensive remediation efforts.
