AI-suggested

  1. Restrict the sources of CHX files to trusted and verified origins only, implementing strict file transfer and sharing policies.
  2. Employ application whitelisting to prevent execution of unauthorized or suspicious files within the VectorStar environment.
  3. Educate users on the risks of opening unsolicited or unexpected CHX files and visiting untrusted websites.
  4. Monitor network and endpoint logs for unusual activity related to VectorStar, such as unexpected file openings or process behaviors.
  5. Isolate VectorStar installations in segmented network zones to limit potential lateral movement if compromised.
  6. Regularly back up critical data and configurations to enable recovery in case of compromise.
  7. Engage with Anritsu for timely updates or patches and apply them as soon as they become available.
  8. Consider deploying endpoint detection and response (EDR) solutions capable of detecting deserialization attack patterns or anomalous code execution within VectorStar processes.

Description

CVE-2025-15350 is a high-severity remote code execution vulnerability in Anritsu VectorStar version 2024.11.1. It arises from improper validation during the parsing of CHX files, leading to deserialization of untrusted data. Exploitation requires user interaction, such as opening a malicious file or visiting a crafted webpage. Successful exploitation allows attackers to execute arbitrary code with the privileges of the current process, impacting confidentiality, integrity, and availability. No known exploits are currently in the wild. The vulnerability is rated with a CVSS score of 7.8, reflecting its significant risk. European organizations using Anritsu VectorStar, particularly in telecommunications and electronics testing sectors, should prioritize patching and implement strict file handling policies.
