## Summary

BigFix Mobile's MDM App Catalog and App Store preview can be attacked remotely over the network by a user with low-privilege login, but it requires a victim to interact with the crafted content. Successful exploitation lets an attacker inject HTML that runs script in the victim's session, which can expose sensitive data.

## Affected

## Description

The MDM App Catalog / App Store preview does not properly sanitize or encode user-supplied HTML before rendering it. Injected HTML can be displayed to users who view the preview, which may allow cross-site scripting (XSS) when a user interacts with the crafted content.
