CVE-2022-0652

Password-hash disclosure via insecure confd logs

Published Mar 21, 2022 · Updated Aug 2, 2024

Sensitive-data exposure in Sophos UTM before 9.710 allows local users to obtain SHA512crypt password hashes from confd log files. Configuration management writes local-account hashes, including root's, into confd*.log files that have insecure access permissions. Local shell access is required; exposed hashes support offline password cracking, while the published impact excludes direct modification or service interruption.
