CVE-2023-1719 Scanner Detail

Bitrix24 is a comprehensive collaboration platform offering a wide range of business management and communication tools. It integrates CRM, project management, contact center, website builder, and HR system functionalities, catering to the diverse needs of businesses aiming to streamline operations and enhance productivity. This platform is widely used by companies worldwide to manage sales, communication, tasks, and projects in a centralized manner. The software is crucial for organizations looking to improve collaboration, customer engagement, and overall operational efficiency. The vulnerability affects version 22.0.300, highlighting the need for rigorous security practices in web-based applications.

CVE-2023-1719 represents a critical vulnerability in Bitrix24 version 22.0.300, where global variable extraction mechanisms can be exploited by unauthenticated attackers. This flaw allows attackers to enumerate server attachments and execute arbitrary JavaScript code within victims' browsers. Furthermore, if the victim has administrative privileges, it could potentially lead to arbitrary PHP code execution on the server. The exploitation of this vulnerability underscores the significant risks associated with improper input validation and variable handling.

The issue stems from the improper handling of global variables in the bitrix/modules/main/tools.php file, specifically within the socialnetwork.events_dyn/get_message_2.php component. By manipulating the log_cnt parameter, attackers can inject malicious scripts that are executed when the page is rendered in a user's browser. This attack vector not only compromises the integrity of the session but also poses a risk of further escalation, depending on the privileges of the session compromised. This highlights the critical importance of sanitizing input to prevent unauthorized actions on the platform.

Successful exploitation of this XSS vulnerability can lead to data theft, unauthorized access to user sessions, modification of displayed content, and potentially server-side code execution. The ability to run arbitrary scripts in the context of the user's session can compromise the security and privacy of user data, undermine the trust in the application, and cause significant reputational damage to the organization using Bitrix24.
