critical Nessus Plugin ID 278762

Language:

Synopsis

An application installed on the remote macoOS host is affected by a remote code execution vulnerability.

Description

The version of iTerm2 installed on the remote host is prior to 3.4.20. It is, therefore, is affected by multiple vulnerabilities:

 - iTerm2 before 3.4.20 allow (potentially remote) code execution because of mishandling of certain escape sequences related to tmux integration. (CVE-2023-46300)

 - iTerm2 before 3.4.20 allow (potentially remote) code execution because of mishandling of certain escape sequences related to upload. (CVE-2023-46301)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to iTerm2 version 3.4.20, 3.5.0beta11 or later.
