  script_tag(name:"insight", value:"Certain Xerox WorkCentre printers do not require the user to reenter or
  validate LDAP bind credentials when changing the LDAP connector IP address. A malicious actor who gains access
  to affected devices (e.g., by using default credentials) can change the LDAP connection IP address to a system
  owned by the actor without knowledge of the LDAP bind credentials. After changing the LDAP connection IP address,
  subsequent authentication attempts will result in the printer sending plaintext LDAP (Active Directory)
  credentials to the actor. Although the credentials may belong to a non-privileged user, organizations frequently
  use privileged service accounts to bind to Active Directory. The attacker gains a foothold on the Active
  Directory domain at a minimum, and may use the credentials to take over control of the Active Directory domain.");
