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 · unedited
Anritsu VectorStar CHX File Parsing Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Anritsu VectorStar. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of CHX files. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-27039.

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 confidence

This is a deserialization vulnerability in Anritsu VectorStar's CHX file parser. The application fails to properly validate user-supplied data during CHX file parsing, allowing an attacker to embed malicious serialized data that gets deserialized, leading to arbitrary code execution in the context of the current process.

MitigationDisable or restrict CHX file parsing capabilities until an official vendor patch is available; implement file type validation and sandboxing for file import features; train users to only open CHX files from trusted sources.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify Anritsu VectorStar installation
    Search for VectorStar application files or check installed programs list - common install paths may include C:\Program Files\Anritsu\VectorStar or /opt/anritsu/vectorstar on Linux
    Affected if Anritsu VectorStar software is present on the system
  2. Identify installed VectorStar version
    Check application version through installed programs list, executable file properties, or application About/Help menu. Look for version information in the main VectorStar executable or associated DLLs
    Affected if Installed version equals exactly 2024.11.1
  3. Confirm CHX file parser module exists
    Search for CHX-related DLLs or parsers in the VectorStar installation directory - look for files with 'chx' in the name or associated with file import/parsing functionality
    Affected if CHX file parsing module is present in the installation
  4. Verify CHX file parsing is accessible
    Check if the application allows importing or opening CHX files through its UI or command-line interface. Review application settings or feature configuration for file import capabilities
    Affected if CHX file import/parsing feature is available or enabled in the application

The environment is affected if Anritsu VectorStar version 2024.11.1 is installed and the CHX file parsing functionality is present and accessible.
