"value": "The below process can protect against a Remote Code Execution attack by disabling the LoginGraceTime parameter on Red Hat Enterprise Linux 9. However, the sshd server is still vulnerable to a Denial of Service if an attacker exhausts all the connections.\n\n1) As root user, open the /etc/ssh/sshd_config\n2) Add or edit the parameter configuration:\n~~~\nLoginGraceTime 0\n~~~\n3) Save and close the file\n4) Restart the sshd daemon:\n~~~\nsystemctl restart sshd.service\n~~~\n\nSetting LoginGraceTime to 0 disables the SSHD server\u0027s ability to drop connections if authentication is not completed within the specified timeout. If this mitigation is implemented, it is highly recommended to use a tool like \u0027fail2ban\u0027 alongside a firewall to monitor log files and manage connections appropriately.\n\nIf any of the mitigations mentioned above is used, please note that the removal of LoginGraceTime parameter from sshd_config is not automatic when the updated package is installed."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
