TITLE

Apple macOS of 802.1X Vulnerability in obtaining network credentials of arbitrary user in component

Trust: 0.8

sources: JVNDB: JVNDB-2017-003849

DESCRIPTION

An issue was discovered in certain Apple products. macOS before 10.12.5 is affected. The issue involves the "802.1X" component. It allows remote attackers to discover the network credentials of arbitrary users by operating a crafted network that requires 802.1X authentication, because EAP-TLS certificate validation mishandles certificate changes. Apple macOS is prone to multiple security vulnerabilities. An attacker can exploit these issues to gain elevated privileges, perform unauthorized actions and execute arbitrary code with kernel privileges. Failed exploit attempts will likely cause a denial-of-service condition. Apple macOS Sierra is a dedicated operating system developed by Apple for Mac computers. 802.1X is one of the client or server-based access control and authentication protocol components. The vulnerability stems from the fact that EAP-TLS certificate verification does not properly handle certificate replacement
