NVD Description

Note: Versions mentioned in the description apply only to the upstream xrdp package and not the xrdp package as distributed by Alpine. See How to fix? for Alpine:3.23 relevant fixed versions and status.

In the xrdp package (in branches through 3.14) for Alpine Linux, RDP sessions are vulnerable to man-in-the-middle attacks because pre-generated RSA certificates and private keys are used.
