CVE-2022-27926 Scanner Detail

Zimbra Collaboration (ZCS) is a popular open-source email, calendar, and collaboration suite used by enterprises, service providers, and educational institutions worldwide. It offers a feature-rich web client experience, with capabilities ranging from email and calendar to file sharing, instant messaging, and video conferencing. Zimbra is known for its flexibility, scalability, and extensive integration options, making it a comprehensive solution for organizations looking to manage their communication and collaboration needs efficiently. Its widespread adoption underscores the importance of maintaining strong security measures to protect sensitive information and user privacy.

CVE-2022-27926 is a reflected cross-site scripting (XSS) vulnerability identified in Zimbra Collaboration (ZCS) version 9.0. This security flaw is present in the /public/launchNewWindow.jsp component, allowing attackers to inject arbitrary web scripts or HTML via request parameters. Such vulnerabilities pose significant risks as they can be exploited to execute malicious scripts in the context of a victim's browser, potentially leading to unauthorized access to sensitive data, session hijacking, and other malicious activities.

The vulnerability arises due to improper sanitization of user-supplied input in the 'errCode' parameter of the error.jsp page. By crafting a malicious URL containing a specific XSS payload, an attacker can trigger the execution of arbitrary JavaScript code in the browser of any user who clicks on the link. This exploit can lead to various security breaches, including the theft of session cookies, personal data, and other exploitable information stored in the browser or associated with the user's session on the Zimbra Collaboration platform.

Exploiting this XSS vulnerability in Zimbra Collaboration can have severe consequences, including but not limited to, compromise of user accounts, unauthorized access to sensitive emails and documents, alteration of user data, and the spreading of malware to other users within the organization. The impact is particularly concerning in environments where Zimbra serves as the central hub for communication and collaboration, emphasizing the need for prompt remediation.
