Description

In versions of the Datadog Android application prior to v541-5.9.2, the exported launcher activity AppActivity accepts an attacker-supplied session (including OAuth tokens) from Intent extras with no permission guard, and signs the app into that session without validating it against the backend. This requires a malicious application co-installed on a device with the Datadog app installed, and an OAuth token the attacker is willing to load into the victim's app. Impact: A co-installed application can switch the victim's Datadog app to a session the attacker controls. This is an account-confusion issue; it does not by itself expose the victim's existing session or data.

Affected products

Datadog Android App: from 5.9.2 before 5.9.2 — fixed in 5.9.2

How to fix

Upgrade to a fixed version: Datadog Android App 5.9.2. Check the vendor advisory for mitigations.
