Severity

high7.1

CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Public exploit

Not established by this record

Missing evidence does not mean no public exploit exists.

Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

P-Net before 1.0.4 stores a refused DCP Set's IP suite, which may be used after a restart. A host with adjacent network access can exploit this while an Application Relationship is active. The device may not answer the controller or use its address.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Public exploit evidence

No public exploit reference is identified in the imported evidence. This is not a claim that no exploit exists.

Original source description

Read the full publisher 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.
