If this vulnerability is exploited, information may be disclosed or arbitrary code may be executed by having a user of KV STUDIO PLAYER open a specially crafted file.
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 confidenceOut-of-bounds read vulnerability in KV STUDIO and KV REPLAY VIEWER file parsing functionality. Exploitation occurs when a user opens a specially crafted file in KV STUDIO PLAYER, potentially allowing disclosure of sensitive information or execution of arbitrary code due to improper bounds checking during file processing.

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.
-
Identify installed KV STUDIO versionLocate KV STUDIO installation (typically in Program Files or Program Files (x86) under Keyence) and check the version. This can often be done by right-clicking the executable, selecting Properties, and viewing the Details tab, or by opening the application and checking Help > About KV STUDIOAffected if The installed version is lower than 11.63 (e.g., 11.50, 11.00, etc.)
-
Identify installed KV REPLAY VIEWER versionLocate KV REPLAY VIEWER installation and check its version via the executable properties or by accessing Help > About in the application menuAffected if The installed version is lower than 2.63 (e.g., 2.50, 2.00, etc.)
-
Determine if file parsing features are in useThe vulnerability is triggered when opening specially crafted files in KV STUDIO PLAYER or KV REPLAY VIEWER. Check whether users routinely import or open files in these applications, particularly from external or untrusted sourcesAffected if Users open or parse files within KV STUDIO PLAYER or KV REPLAY VIEWER, especially files originating from untrusted or external sources
A system is affected if KV STUDIO version is below 11.63 OR KV REPLAY VIEWER version is below 2.63, AND users have the ability to open files within these applications.
