Vulnerability from csaf_mbconnectlinegmbh - Published: 2023-08-17 12:00 - Updated: 2023-08-17 12:00Summary
MB connect line: Multiple products are vulnerable to regreSSHion
Notes
Summary: Several Red Lion Europe products are vulnerable to a possible race condition vulnerability in OpenSSH named "regreSSHion".
Impact: Possible full system compromise where an attacker can execute arbitrary code with the highest privileges.
Mitigation: Prevent all access to the sshd daemon listening on port 22.
Remediation: Update to latest firmware:
2.16.1 for mbCONNECT24/mymbCONNECT24
8.2.0 for mbNET/mbNET.rokey
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.
8.1 (High)
Mitigation
Prevent all access to the sshd daemon listening on port 22.
Vendor Fix
Update to latest firmware:
2.16.1 for mbCONNECT24/mymbCONNECT24
8.2.0 for mbNET/mbNET.rokey
