CVE-2022-48310

Key-material disclosure via technical support archives

Published Mar 1, 2023 · Updated Mar 7, 2025

Information disclosure in Sophos Connect before 2.2.90 allows local users to obtain sensitive key material from support archives. The client writes sensitive key material into generated technical support archives instead of excluding it from diagnostic output. A low-privileged local user who can access an archive can recover the included keys; no integrity or availability impact is reported.
