Base vector

AV:N/AC:M/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions Heimdal versions prior to 10.11

Description The issue is related to inadequate access control in the Heimdal component of the Mac OS X operating system. It allows a remote attacker to conduct replay attacks against the SMB server by exploiting packet data that represents a Kerberos authenticated request. This could potentially enable the attacker to perform network attacks on the SMB server.

Recommendations For versions prior to 10.11, update to version 10.11 or later to resolve the issue. As a temporary workaround, consider restricting access to the SMB server to minimize the risk of exploitation.
