Name of the Vulnerable Software and Affected Versions Zyxel CloudCNM SecuManager versions 3.1.0 through 3.1.1

Description The issue is related to a hardcoded Erlang cookie for ejabberd replication in Zyxel CloudCNM SecuManager. Additionally, there is a problem with unencrypted storage of credentials. This could allow a remote attacker to gain unauthorized access to protected information.

As a temporary workaround, restrict access to the replication functionality until a patch is available.
