CVE-2023-28616

Credential disclosure via plaintext serverd logging

Published Dec 26, 2023 · Updated Aug 2, 2024

Cleartext logging in Stormshield Network Security before 4.3.17, 4.4.0 through 4.6.3, and 4.7.0 allows attackers to read passwords. The serverd process writes passwords containing an equals sign or space to logs without masking them and can forward those entries to Syslog. Exposure requires such a password and access to serverd logs or the configured Syslog destination; the consequence is disclosure of the affected account credential.
