CVE Record

CVE-2022-34464: A vulnerability has been identified in SICAM GridEdge (Classic) (All versions < V2.7.3).

A vulnerability has been identified in SICAM GridEdge (Classic) (All versions < V2.7.3). The affected application uses an improperly protected file to import SSH keys. This could allow attackers with access to the filesystem of the host on which SICAM GridEdge runs to inject a custom SSH key to that file.

Security readout for executives and security teams

Plain-English summary

Siemens SICAM GridEdge (Classic) before V2.7.3 can trust an SSH-key import file that is not properly protected. Someone who already has access to the host filesystem could place their own key and potentially gain unauthorized access or persistence.

Executive priority

Treat as a moderate priority for OT and grid-edge environments. It is not documented as actively exploited, but unauthorized SSH key insertion can support persistence on operational infrastructure.

Technical view

CVE-2022-34464 is a CWE-552 exposure of a sensitive file or directory. The affected application uses an improperly protected file for SSH key import. Siemens lists SICAM GridEdge (Classic) all versions before V2.7.3 as affected. CVSS v3.1 is 6.3 with low confidentiality, integrity, and availability impact.

Likely exposure

Exposure is limited to environments running Siemens SICAM GridEdge (Classic) below V2.7.3, especially where users or processes can access the host filesystem.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation. The described attacker needs filesystem access on the host, so this is most urgent where host access controls are weak or shared.

Researcher notes

Evidence is limited to the CVE record and Siemens advisory references. The description emphasizes filesystem access to the host, while the CVSS vector is AV:N/PR:L. Do not assume broader remote exploitability without vendor details.

Mitigation direction

  • Upgrade SICAM GridEdge (Classic) to V2.7.3 or later where deployed.
  • Review Siemens advisory SSA-225578 for vendor-specific guidance.
  • Restrict host filesystem access to authorized administrators and service accounts.
  • Harden monitoring around SSH key import and configuration changes.

Validation and detection

  • Inventory all SICAM GridEdge (Classic) deployments and record versions.
  • Flag any instance running a version earlier than V2.7.3.
  • Review permissions on files used for SSH key import against Siemens guidance.
  • Check for unexpected SSH key additions or configuration changes on affected hosts.
