high Nessus Plugin ID 73472
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote AIX host is running a vulnerable version of OpenSSL.

Description

The version of OpenSSL running on the remote host is affected by an information disclosure vulnerability.

OpenSSL incorrectly handles memory in the TLS heartbeat extension, potentially allowing a remote attacker to read the contents of up to 64KB of server memory, potentially exposing passwords, private keys, and other sensitive data.

Solution

Install the appropriate interim fix. Additionally, to address this issue you must :

- Replace your SSL certificates by revoking existing certificates and reissuing new certificates, with a new private key generated by 'openssl genrsa'.

- Reset User Credentials Force users to reset their passwords and revoke any existing cookies or authentication prior to the re-authentication.
