LDAP Anonymous Bind

  • Linux hosts running open-source versions of LDAP and Linux vCenter appliances are often configured to allow anonymous binds.

Scan for ldap ports

sudo nmap -p 389,636 <RANGE>

Check if connecting without credentials is allowed

  • Python
from ldap3 import *
s = Server('<IP>',get_info = ALL)
c =  Connection(s, '', '')
c.bind()
True
s.info

Confirm anonymous bind

ldapsearch -h <IP> -p 389 -x -b "dc=<DOMAIN>,dc=local"
