Pre-auth memory corruption in HPE Serviceguard

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A pre-authentication memory corruption vulnerability in HPE Serviceguard allows remote attackers to execute arbitrary code or cause denial of service without requiring any credentials. The memory corruption likely stems from improper bounds checking or unsafe memory operations in the Serviceguard component handling network requests.

MitigationApply the HPE security bulletin and patch for CVE-2022-37937 immediately. If no patch is available, consider network segmentation or disabling exposed Serviceguard interfaces until remediation is possible.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Serviceguard version
    Run 'rpm -qa | grep -i serviceguard' or check /opt/serviceguard/version to find the installed version package
    Affected if The installed version is lower than a.12.80.05 (for example, a.12.70.xx or earlier)
  2. Verify Serviceguard processes are running
    Run 'ps -ef | grep -i serviceguard' or 'systemctl status cmx*' to check if Serviceguard daemons are active
    Affected if Serviceguard processes (such as cmx, cmlogd, or related network services) are running and exposed to network access
  3. Identify listening network ports
    Run 'netstat -tlnp | grep -E "(cmx|cms|serviceguard)"' or 'ss -tlnp' to find ports bound by Serviceguard components
    Affected if Serviceguard is listening on network interfaces accessible from untrusted networks (especially ports 5000x, 5432/5433, or other Serviceguard-specific ports)
  4. Check network binding configuration
    Inspect /etc/cmcluster/cmx/cmx.conf or similar Serviceguard configuration files to determine which IP addresses the service binds to
    Affected if Serviceguard is bound to 0.0.0.0 or an interface on a public/exposed network rather than localhost or a protected segment

The environment is affected if Serviceguard for Linux is installed with a version below a.12.80.05 and the Serviceguard network interfaces are accessible to remote attackers.

Mitigation

Apply the HPE security bulletin and patch for CVE-2022-37937 immediately. If no patch is available, consider network segmentation or disabling exposed Serviceguard interfaces until remediation is possible.

Recommended fix High confidence

a.12.80.05 or later

  1. Backup all Serviceguard configuration files and cluster state data
  2. Stop the HPE Serviceguard service on all cluster nodes
  3. Download HPE Serviceguard for Linux version a.12.80.05 or later from support.hpe.com
  4. Install the updated Serviceguard package on each cluster node using the appropriate package manager (e.g., rpm or dpkg)
  5. Verify the installation succeeded by checking the installed version matches a.12.80.05 or later
  6. Restart the Serviceguard service on all cluster nodes
  7. Validate cluster health and functionality after upgrade
