Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2304 advisory.

 A flaw was found in pki-core, which could allow a user to get a certificate for another user identity when directory-based authentication is enabled. This flaw allows an authenticated attacker on the adjacent network to impersonate another user within the scope of the domain, but they would not be able to decrypt message content. (CVE-2022-2393)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update pki-core' to update your system.
