CVE-2022-46934 Scanner Detail

kkFileView is a powerful document and image preview tool that supports a broad range of file formats, including PDF, DOCX, PPTX, XLSX, and many others. Developed to provide web applications with the capability to display file contents directly in the browser without the need for downloading or using external software, kkFileView is widely adopted in enterprise environments for document management systems, collaboration platforms, and other web applications. Its versatility and ease of integration make it a preferred choice for developers looking to enhance the user experience by offering immediate access to document contents.

The Cross-Site Scripting vulnerability in kkFileView version 4.1.0 arises from insufficient input validation and output encoding mechanisms. This flaw allows attackers to inject malicious scripts into web pages via the url parameter in the OnlinePreviewController.java component. When these scripts are executed in the context of a victim's browser, they can lead to various security breaches such as session hijacking, sensitive information theft, and manipulation of displayed content.

Specifically, the vulnerability can be exploited by crafting a malicious link that includes JavaScript code in the url parameter. When an unsuspecting user clicks on this link, the injected script is executed within their browser under the domain of the kkFileView application. This execution can result in unauthorized actions performed on behalf of the user, including cookie theft, account compromise, and exposure of personal data. The vulnerability highlights a critical oversight in the application's security measures regarding user input handling.

The impact of exploiting this XSS vulnerability can be significant, affecting both users and the organizations deploying kkFileView. Attackers can gain unauthorized access to user sessions, modify web page contents, redirect users to phishing sites, and perform actions maliciously without the user's consent. Such incidents can undermine the security and integrity of the affected web applications, leading to potential data breaches, loss of user trust, and reputational damage.
