GCP-2024-040

Published: 2024-07-01

Description Severity Notes

A vulnerability CVE-2024-6387 was discovered in OpenSSH server (sshd). This vulnerability is exploitable remotely on glibc-based linux systems: an unauthenticated remote code execution as root, because it affects sshd's privileged code, which is not sandboxed and runs with full privileges.

At the time of publication, exploitation is believed to be difficult–requiring winning a race condition, which is hard to successfully exploit and may take several hours per machine being attacked. We are not aware of any exploitation attempts.

What should I do?

  1. Apply updates from Linux distributions to your workloads as they become available. Please refer to guidance from Linux distributions.
  2. If updating is not possible, consider turning OpenSSH off until it can be patched.
  3. If OpenSSH needs to be left on, you can also execute a configuration update which eliminates the race case condition for the exploit. This is a runtime mitigation. To apply the changes in the sshd config, this script will restart the sshd service. 
    #!/bin/bash
set -e

SSHD_CONFIG_FILE=/etc/ssh/sshd_config
# -c: count the matches
# -q: don't print to console
# -i: sshd_config keywords are case insensitive.
if [[ "$(grep -ci '^LoginGraceTime' $SSHD_CONFIG_FILE)" -eq 0 ]]; then
    echo "LoginGraceTime 0" >> "$SSHD_CONFIG_FILE"
    echo "Set the LoginGraceTime to 0 in $SSHD_CONFIG_FILE"
else
    sed -i 's/^LoginGraceTime.*$/LoginGraceTime 0/' /etc/ssh/sshd_config
    echo "Changed the LoginGraceTime to 0 in $SSHD_CONFIG_FILE"
fi
# Restart the sshd service to apply the new config.
systemctl restart sshd
  4. Finally, monitor for any unusual network activity involving SSH servers.

Description Severity Notes

VMware disclosed multiple vulnerabilities in VMSA-2023-0023 that impact vCenter components deployed in customer environments.

VMware Engine impact

  • The vulnerability can be exploited by accessing specific ports in vCenter Server. These ports are not exposed to the public internet.
  • If your vCenter ports 2012/tcp, 2014/tcp, and 2020/tcp are not accessible by untrusted systems, then you are not exposed to this vulnerability.
  • Google has already blocked the vulnerable ports on vCenter server, preventing any potential exploit of this vulnerability.
  • In addition, Google will ensure all future deployments of vCenter server are not exposed to this vulnerability.
  • At the time of the bulletin, VMware is not aware of any exploitation "in the wild". For more details please refer to the VMware documentation for more information.

What should I do?

No further action is required at this time.
