CVE-2025-48021
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability has been found in Vnet/IP Interface Package provided by Yokogawa Electric Corporation. If affected product receives maliciously crafted packets, Vnet/IP software stack process may be terminated. The affected products and versions are as follows: Vnet/IP Interface Package (for CENTUM VP R6 VP6C3300, CENTUM VP R7 VP7C3300) R1.07.00 or earlier
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 confidenceA Denial of Service vulnerability exists in Yokogawa's Vnet/IP Interface Package software stack. When the affected product receives maliciously crafted packets, the Vnet/IP software stack process terminates unexpectedly, causing service disruption.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify Vnet/IP Interface Package is installedLocate the Vnet/IP software on the system by checking installed programs, program files directories, or Yokogawa-specific installation pathsAffected if The software is present on the system
-
Determine installed version of Vnet/IP Interface PackageUse the software's built-in version information feature, check the About dialog, or locate version details in the installation directory or release notesAffected if The version cannot be determined or is older than R1.08.00
-
Compare version against affected rangeCompare the installed version number to r1.08.00 - any version prior to R1.08.00 (such as R1.07.00 or earlier) falls within the affected rangeAffected if The installed version is less than r1.08.00
-
Assess network exposure of Vnet/IP serviceCheck firewall rules and network configuration to determine if the Vnet/IP interface is accessible from untrusted networksAffected if The Vnet/IP interface is exposed to untrusted network segments
The environment is affected if Yokogawa Vnet/IP Interface Package is installed with a version lower than r1.08.00 and the service is network-accessible.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply vendor-supplied patch to upgrade Vnet/IP Interface Package beyond R1.07.00. Network segmentation and firewall rules can limit exposure by restricting access to the Vnet/IP interface to trusted sources until patching is complete.
Vnet/IP Interface Package R1.08.00
- Obtain Vnet/IP Interface Package R1.08.00 or later from Yokogawa Electric Corporation via official channels (reference: web-material3.yokogawa.com)
- Follow Yokogawa's standard upgrade procedure for Vnet/IP Interface Package
- After upgrade, verify that the Vnet/IP software stack process is running normally
- Test that the system properly handles network packets to confirm the vulnerability is remediated
