CVE-2021-38378Public exploitNetwork attack vector

Authenticated name disclosure via context-omitting cache

Published Nov 22, 2021 · Updated Aug 4, 2024

Information disclosure in OX App Suite 7.10.5 allows remote authenticated users to read other users' names through OX Drive. The middleware file cache keys objects without their context identifiers, so equal file identifiers in different contexts can reuse another user's Modified By metadata. The collision is chance-dependent and exposes only a surname and given name; the vendor found no evidence of file-content exposure.
