4.3

Medium

Base vector

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

Name of the Vulnerable Software and Affected Versions Apple OS X versions prior to 10.11

Description The issue is related to the X.509 certificate-trust implementation, which does not properly handle revocation checking. This makes it easier for attackers to conduct man-in-the-middle attacks by using a revoked certificate. The vulnerability can be exploited by a remote attacker to spoof endpoints.

Recommendations For Apple OS X versions prior to 10.11, update to version 10.11 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive resources to minimize the risk of exploitation.
