CVE-2024-56182 Siemens CVE debrief

Who should care

OT and industrial IT teams running Siemens SIMATIC Field PG or SIMATIC IPC systems, especially administrators who rely on BIOS passwords or manage device firmware and physical access controls.

Technical summary

The supplied description says affected devices have insufficient protection for EFI variables stored on the device. The CVSS v4.0 vector (AV:L/PR:H/UI:N) indicates a local attack requiring high privileges. Per the record, an authenticated attacker may be able to directly communicate with the flash controller and disable the BIOS password. NVD maps the weakness to CWE-693 and lists the vulnerability status as Deferred.

Defensive priority

High. The issue affects many Siemens SIMATIC industrial PC and Field PG platforms and can undermine BIOS password protections that organizations may rely on for device hardening and physical security.

Recommended defensive actions

• Review Siemens advisory SSA-216014 and apply the vendor-recommended firmware/BIOS update for each affected model.
• Confirm every deployed SIMATIC Field PG/IPC variant is on a remediated version or later, especially where the description lists all versions as affected.
• Restrict local administrative access and physical access to affected systems until remediation is complete.
• Audit whether BIOS password controls are used as a security boundary and add compensating controls where needed.
• Track remediation status across engineering workstations and embedded IPC fleets, including spare and field-deployed units.

Evidence notes

The vulnerability description and product scope come from the supplied CVE text and the Siemens advisory reference linked by NVD (SSA-216014). NVD metadata shows CVSS v4.0 8.4 HIGH, vector AV:L/PR:H/UI:N, CWE-693, and vulnStatus 'Deferred' as of the latest supplied modification date (2026-05-12). No exploit details or unsupported remediation versions are included beyond the supplied advisory reference.
