Mac Lion blindly accepts any LDAP password

Apple's latest version of Mac OS X is creating serious security risks for businesses that use it to interact with a popular form of centralized networks.

People logging in to Macs running OS X 10.7, aka Lion, can access restricted resources using any password they want when the machines use a popular technology known as LDAP for authentication. Short for Lightweight Directory Access Protocol, LDAP servers frequently contain repositories of highly sensitive enterprise data, making them a goldmine to attackers trying to burrow their way in to sensitive networks.

“As pen testers, one of the first things we do is attack the LDAP server,” Rob Graham, CEO of auditing firm Errata Security, said. “Once we own an LDAP server we own everything. I can walk up to any laptop (in an organization) and log into it.”

Macs may be an excellent choice for individuals looking for a machine that's resistant to today's malware attacks found in the wild, but enterprises should think twice before deploying large fleets of them, a prominent security consultancy said recently. The recommendation is based on the finding that many of the OS X components used to administer Macs lack secure authentication protocols, making networks vulnerable to so-called APTs.
