Microsoft » Baseline Security Analyzer : Security Vulnerabilities, CVEs,

Microsoft Baseline Security Analyzer (MBSA) 1.2 does not correctly identify systems that have been patched but remain vulnerable to exploit until the system is rebooted, possibly giving the administrator a false sense of security.

Microsoft Baseline Security Analyzer (MBSA) 1.0 stores security scans in a known location C:\Documents and Settings\username\SecurityScans in plaintext, which could allow remote attackers to obtain sensitive information about the system via malicious active content such as ActiveX controls or Java.
