EUVDB-ID: #VU42453

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

Apple Remote Desktop before 3.7 does not properly use server authentication-type information during decisions about whether to present an unencrypted-connection warning message, which allows remote attackers to obtain sensitive information in opportunistic circumstances by sniffing the network during an unintended cleartext VNC session.

Mitigation

Install update from vendor's website.
