CVE-2007-2999

no score yetEPSS 1.6%

Microsoft Windows Server 2003, when time restrictions are in effect for user accounts, generates different error messages for failed login attempts with a valid user name than for those with an invalid user name, which allows context-dependent attackers to determine valid Active Directory account names.

EPSS: 1.6% chance of exploitation in the next 30 days; higher than 76% of CVEs (scores of 2026-10-31)
