Summary
PHOENIX CONTACT: Denial-of-Service vulnerability in mGuard product family
Notes
Summary: A denial of service of the HTTPS management interface of PHOENIX CONTACT FL MGUARD and TC MGUARD devices can be triggered by a larger number of unauthenticated HTTPS connections originating from different source IP's. Configuring firewall limits for incoming connections cannot prevent the issue.
Mitigation: Don't allow access to the HTTPS management interface from untrusted networks.In the default configuration, the access is only allowed from internal interfaces.
Remediation: The vulnerability is fixed in firmware version 8.9.0. We strongly recommend all affected users to upgrade to this or a later version.
CVE-2022-3480

A remote, unauthenticated attacker could cause a denial-of-service of PHOENIX CONTACT FL MGUARD and TC MGUARD devices below version 8.9.0 by sending a larger number of unauthenticated HTTPS connections originating from different source IP's. Configuring firewall limits for incoming connections cannot prevent the issue.
