API, hardcoded credentials were identified and removed which can impact both the SRX Series device, and
potentially LDAP and Active Directory integrated points.

Credentials may be taken from the network via man-in-the-middle attacks, or other attack vectors, as above, or
others not listed.");

without authentication, other SRX Series devices deployed in the same environment running vulnerable versions of
Junos OS, as well as Active Directory servers and service, including but not limited to, user accounts,
workstations, servers performing other functions such as email, database, etc. which are also tied to the Active
Directory deployment. Inter-Forest Active Directory deployments may also be at risk as the attacker may gain full
administrative control over one or more Active Directories depending on the credentials supplied by the
administrator of the AD domains and SRX devices performing integrated authentication of users, groups and
devices.");
