CVE-2024-6388

Subscription token disclosure via plaintext process argument

Published Jun 27, 2024 · Updated Aug 1, 2024

Information disclosure in Canonical Ubuntu Pro Desktop before 1.12 allows local users to read the Pro subscription token via process listings. The desktop daemon invokes the Pro client with the attach token as a plaintext command-line argument, exposing it through simple process-list output. An unprivileged local account and a concurrent attach operation are required; the disclosed token grants unauthorized access to the associated Ubuntu Pro subscription.
