Description

Maintenance Server, in Cybellum's QCOW air-gapped distribution (China Edition), versions 2.15.5 through 2.27, was compiled with a hard-coded private cryptographic key. An attacker with administrative privileges & access to the air-gapped server could potentially use this key to run commands on the server. The issue was resolved in version 2.28.
