Related Threats

MITRE ATT&CK Enterprise TechniquesAI

T1059.007 JavaScript Execution
Adversaries may abuse various implementations of JavaScript for execution.
T1189 Drive-by Compromise Initial Access
Adversaries may gain access to a system through a user visiting a website over the normal course of browsing.
Why these techniques?

The stored XSS vulnerability enables authenticated high-privilege users (admin+) to inject arbitrary JavaScript into calendar settings, which executes in the browsers of other users viewing the calendar list page, facilitating JavaScript command execution (T1059.007) and drive-by compromise via a legitimate but compromised site (T1189).
