Executive Summary

This vulnerability in Emby Server allows a malicious user to send an authentication request with a manipulated X-Emby-Client value. This manipulated value is then added to the devices section of the admin dashboard without proper sanitization, potentially allowing the attacker to inject malicious data or cause unexpected behavior. The issue affects versions prior to 4.8.1.0 and Beta versions prior to 4.9.0.0-beta and has been patched in those versions.

Impact Analysis

The vulnerability can impact you by allowing an attacker to inject manipulated data into the admin dashboard's devices section, which could lead to misleading information being displayed or potentially further exploitation depending on how the unsanitized data is handled. This could compromise the integrity of the admin interface and potentially affect the security of the server.

Mitigation Strategies

The immediate step to mitigate this vulnerability is to update Emby Server to version 4.8.1.0 or later, or to Beta version 4.9.0.0-beta or later, where the issue has been patched.
