CVE-2020-15325Network attack vector

Unauthenticated Erlang cookie disclosure via hardcoded secret

Published Jun 26, 2020 · Updated Aug 4, 2024

Sensitive information exposure in Zyxel CloudCNM SecuManager 3.1.0 and 3.1.1 allows remote attackers to obtain an ejabberd Erlang cookie. The appliance stores the same static replication secret in /opt/production_xmpp/var/lib/ejabberd/.erlang.cookie instead of generating a deployment-specific value. Knowledge of the embedded value defeats per-deployment secrecy for ejabberd node authentication; no data modification or service interruption is attributed.
