CVE-2020-14519: 
Wibu-Systems CodeMeter vulnerability analysis and mitigation

The vulnerability CVE-2020-14519 affects Wibu-Systems CodeMeter, a license manager software, in all versions prior to 7.10a. This Origin Validation Error vulnerability (CWE-346) was discovered in 2020 and allows attackers to use the internal WebSockets API via specifically crafted JavaScript payloads (CISA Advisory).

The vulnerability enables attackers to interact with the internal WebSockets API through crafted JavaScript payloads, which when combined with CVE-2020-14515, could lead to the alteration or creation of license files. The vulnerability has been assigned a CVSS v3 base score of 8.1, with the vector string (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H), indicating it is network-accessible with low attack complexity (CISA Advisory).

Successful exploitation of this vulnerability, particularly when combined with other CodeMeter vulnerabilities, could allow attackers to alter and forge license files, cause denial-of-service conditions, potentially achieve remote code execution, read heap data, and prevent normal operation of third-party software dependent on CodeMeter (CISA Advisory, Threatpost).

Wibu-Systems recommends several mitigation steps including: updating to the latest version of the CodeMeter Runtime, running CodeMeter only as client, utilizing the new REST API instead of the internal WebSockets API, disabling the WebSockets API, and applying AxProtector. Additionally, CISA recommends minimizing network exposure for control system devices and ensuring they are not accessible from the Internet (CISA Advisory).
