CVE-2013-4496: n/a vulnerability

CVE-2013-4496: Samba 3.x before 3.6.23, 4.0.x before 4.0.16, and 4.1.x before 4.1.6 does not enforce the password-guessing...

Samba 3.x before 3.6.23, 4.0.x before 4.0.16, and 4.1.x before 4.1.6 does not enforce the password-guessing protection mechanism for all interfaces, which makes it easier for remote attackers to obtain access via brute-force ChangePasswordUser2 (1) SAMR or (2) RAP attempts.

Security readout for executives and security teams

This Samba flaw weakens defenses against password guessing on some password-change interfaces. An attacker able to reach an affected Samba service could make brute-force attempts that should have been protected. The business risk is unauthorized access to file sharing or domain services on old Samba deployments. Exposure is most likely on legacy Linux or Unix systems running Samba releases older than 3.6.23, 4.0.16, or 4.1.6, especially where SMB-related services are reachable by untrusted networks or large user populations. Prioritize remediation where old Samba systems protect sensitive file shares, identity services, or externally reachable networks. This is not KEV-listed in the provided data, but the flaw lowers resistance to account compromise on legacy deployments. Mitigation focus: Upgrade Samba to 3.6.23, 4.0.16, 4.1.6, or later supported vendor packages.; Apply relevant distribution advisories from Red Hat, Ubuntu, Fedora, openSUSE, Gentoo, Mageia, or Mandriva.; Restrict Samba service exposure to trusted networks or VPN-accessible management zones..
