Vulnerabilities in this advisory
- CVE-2021-44221 — CVE-2021-44221 · CWE-20
The affected systems do not properly validate input that is sent to the underlying message passing framework. This could allow a remote attacker to trigger a denial of service of the affected system.
- CVE-2021-44222 — CVE-2021-44222 · CWE-306
The underlying MQTT service of affected systems does not perform authentication in the default configuration. This could allow an unauthenticated remote attacker to send arbitrary messages to the service and thereby issue arbitrary requests in the affected system.
Acknowledgments, as the advisory lists them
- Siemens ProductCERT: reporting these vulnerabilities to CISA.
