Summary
mGuards use an OpenSSH server for SSH access. This server is vulnerable to a remote code injection.
Impact
Attackers can inject code in the SSH server, which is run with high privileges.

Severity
Weakness
Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') (CWE-362)
Summary
A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.
References
Mitigation
Access to the SSH server should be limited to trustworthy networks or peers.
Remote access to the SSH server should be disabled.
Remediation
Phoenix Contact strongly recommends upgrading affected mGuard devices to firmware version 8.9.3 / 10.4.1 or higher which fixes this vulnerability.
