CVE-2008-5112: Microsoft Windows

Medium severity, CVSS 5.0. EPSS: 17.4% chance of exploitation in the next 30 days.

The LDAP server in Active Directory in Microsoft Windows 2000 SP4 and Server 2003 SP1 and SP2 responds differently to a failed bind attempt depending on whether the user account exists and is permitted to login, which allows remote attackers to enumerate valid usernames via a series of LDAP bind requests, as demonstrated by ldapuserenum.

Affected products

• Microsoft Windows: version server_2003 only
• Microsoft Windows 2000: affected versions not specified
