Security vulnerabilities in workplace applications can lead to significant risks for organizations if they are not promptly detected and mitigated. A recently discovered stored cross-site scripting (XSS) vulnerability in VMware Workspace ONE Boxer, a popular business email and calendar application, highlights the importance of adhering to secure coding practices and keeping software updated.

This post delves into the details of CVE-2022-22944, a stored XSS vulnerability in VMware Workspace ONE Boxer, providing insights into the underlying issue, the possible consequences of exploitation, and the relevant patches to mitigate this threat. We will be using simple American language to ensure broad understanding and exclusive content to provide an all-encompassing perspective on the issue.

Exploit Details

The vulnerability, known as CVE-2022-22944, is due to insufficient sanitization and validation processes in VMware Workspace ONE Boxer when handling calendar event descriptions.

Given that the application does not properly screen the content of these descriptions, a malicious actor can inject script tags to execute arbitrary code in the context of a victim's browser when they open the event. In other words, an attacker can take advantage of this security weakness to potentially gather sensitive information, hijack sessions, or manipulate data accessible through the user's account.

Here's a simple code snipplet that demonstrates the vulnerability

<!-- Malicious user injects this script tag in the event description -->
alert('XSS Attack');

If a user opens an event with this malicious script in VMware Workspace ONE Boxer, they would see an alert popup with the text 'XSS Attack,' indicating that the attacker's code has executed within their application.
