CVE-2026-124761

A DCP Set of the IP suite that is refused is still stored

  • High 7.1

Description

P-Net before 1.0.4 copies the IP suite of a DCP Set request to the current and the non-volatile configuration, and starts saving it, before the state of the device is checked. If the request is refused, for example because an Application Relationship is active, the configuration is not restored and is still saved. After a restart the device uses the refused address, and may not answer the controller or may use its address. A host with ADJACENT network access can use this while an Application Relationship is active.

Historical context and remediation

This reference retains the original CVE publication date. A recent record update does not mean a new attack occurred.

No separately sourced impact summary is available on this page yet. Consult the description, version data and dated exploitation evidence.

Version statuses below come from the CNA. An “unaffected” version is not necessarily a currently supported release or proof of a patch date. EPSS is a dated risk estimate, not a count of historical attacks.
