CVE-2009-2818


TITLE

Mac OS X Server of Adaptive Firewall Brute force attack vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2009-002322

DESCRIPTION

Adaptive Firewall in Apple Mac OS X before 10.6.2 does not properly handle invalid usernames in SSH login attempts, which makes it easier for remote attackers to obtain login access via a brute-force attack (aka dictionary attack). Apple Mac OS X is prone to a security-bypass vulnerability. An attacker can exploit this issue to bypass certain security restrictions and perform various attacks. NOTE: This issue was previously covered in BID 36956 (Apple Mac OS X 2009-006 Multiple Security Vulnerabilities), but has been assigned its own record to better document it. This issue affects the following: Mac OS X Server v10.5.8 and prior Mac OS X Server v10.6.1 and prior. Adaptive Firewall responds to suspicious behavior, such as high volumes of access attempts, by creating temporary rules to limit access
