Script execution via unsanitized connection names
Published Jul 26, 2022 · Updated Nov 1, 2024
Cross-site scripting in the InMailX Outlook Plugin before 3.22.0101 allows local users to execute script in other users' Outlook clients. The Outlook tab renders an attacker-controlled SharePoint connection name as HTML without sanitization and executes embedded JavaScript when the server entry is opened. Exploitation requires permission to define or distribute a connection and victim interaction with the crafted entry.
