CVE-2024-7008 Scanner

Calibre is a popular open-source e-book management software used by individuals and organizations to organize, convert, and read e-books. It offers a content server feature, allowing users to access their e-book libraries remotely through a web interface. This software is widely used by e-book enthusiasts for personal use and by libraries or institutions for managing digital collections. The content server is a key feature that provides remote access to the user's library. The software supports various formats and provides tools for editing metadata, managing libraries, and converting between different e-book formats.

The vulnerability detected in Calibre involves a Reflected Cross-Site Scripting (XSS) attack. This vulnerability allows an attacker to inject malicious JavaScript code into the /browse endpoint of the Calibre content server. When a victim clicks a specially crafted URL, the attacker's script is executed in the victim's browser. If the victim is logged into the Calibre server, the attacker can perform actions on behalf of the victim.

The vulnerability is located in the /browse endpoint of the Calibre content server. An attacker can inject arbitrary JavaScript by crafting a URL with malicious code embedded within it. When the victim visits this URL, the malicious code is executed in the context of their browser. The vulnerable parameter is associated with the book_id in the URL, where the attacker's script is inserted. This can lead to the execution of unauthorized actions if the victim is authenticated on the Calibre server.

If exploited, this vulnerability can lead to unauthorized actions being performed on the Calibre server on behalf of the victim, such as modifying or deleting e-books or other data. It can also result in the compromise of the victim's session, potentially exposing sensitive information or allowing further attacks on the system. Additionally, the attack could be used to deliver malware or conduct phishing attacks through the victim's browser.
