Unauthenticated account enumeration via response discrepancies

Published Feb 21, 2024 · Updated Aug 26, 2024

Observable response discrepancy in Livebox Srl vDESK through v031 allows remote attackers to enumerate accounts through public endpoints. The login, shared-search, and user-enabled endpoints return distinguishable responses based on whether supplied account data matches internal state. No authentication or user interaction is required; the differences disclose account or state information without enabling data modification.
