CVE-2007-2999 Details

CVE-2007-2999

Published: 2007-06-04 17:30:00
CVE Author: NIST National Vulnerability Database (NVD)
Summary:

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.

Exploitability Analysis:

This is a vulnerability exploitable with adjacent network access and requires the attacker to have access to either the broadcast or collision domain of the vulnerable software. Examples of local networks include local IP subnet, Bluetooth, IEEE 802.11, and local Ethernet segment.

Exploitability Complexity:

Specialized access conditions exist. For example, in most configurations, the attacking party must already have elevated privileges or spoof additional systems in addition to the attacking system (e.g., DNS hijacking). The attack depends on social engineering methods that would be easily detected by knowledgeable people. For example, the victim must perform several suspicious or atypical actions. The vulnerable configuration is seen very rarely in practice. If a race condition exists, the window is very narrow.

Authentication:

Authentication is not required to access and exploit the vulnerability.

Confidentiality Impact:

There is considerable informational disclosure. Access to some system files is possible, but the attacker does not have control over what is obtained, or the scope of the loss is constrained. An example is a vulnerability that divulges only certain tables in a database.

Integrity Impact:

There is no impact to the integrity of the system.

Availability Impact:

There is no impact to the availability of the system.
