CodeMeter Runtime Predictable Encryption Key

critical Nessus Plugin ID 149307
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

A remote server uses a predictable encryption for secure communication.

Description

The remote CodeMeter runtime server uses a predictable encryption key for secure communication. An unauthenticated, remote attacker, can exploit this, to communicate with the CodeMeter API.

Note that this plugin requires the system time on the scanner to be synchronized with the remote host. If the system times on the scanner and the remote host are off too much, the plugin may fail to detect the vulnerability.

Solution

Upgrade CodeMeter Runtime to version 7.10a or later.
