New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 4.2


The remote Windows host is affected by a security feature bypass vulnerability.


A security feature bypass vulnerability exists in Windows due to the Security Account Manager Remote (SAMR) protocol incorrectly validating the user lockout state. Remote, authenticated attackers can exploit this issue to conduct brute force attacks against user passwords.

Note that the host must have network connectivity to a domain controller.


Microsoft has released a set of patches for Windows 2003, XP, Vista, 2008, 2008 R2, 2012, 2012 R2, and Server Core installation option.
