CWE-319Published: September 7, 2021· Updated: Jun 17, 2026

8.8
CVSS v3.1

Official Description

Barco MirrorOp Windows Sender before 2.5.3.65 uses cleartext HTTP and thus allows rogue software upgrades. An attacker on the local network can achieve remote code execution on any computer that tries to update Windows Sender due to the fact that the upgrade mechanism is not secured (is not protected with TLS).

Technical Analysis

CVE-2021-38142 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
