CVE-2019-1925: Cisco Webex Network Recording Player and Cisco Webex Player Arbitrary Code Execution Vulnerabilities

Multiple vulnerabilities in Cisco Webex Network Recording Player for Microsoft Windows and Cisco Webex Player for Microsoft Windows could allow an attacker to execute arbitrary code on an affected system. The vulnerabilities exist because the affected software improperly validates Advanced Recording Format (ARF) and Webex Recording Format (WRF) files. An attacker could exploit these vulnerabilities by sending a user a malicious ARF or WRF file through a link or email attachment and persuading the user to open the file with the affected software on the local system. A successful exploit could allow the attacker to execute arbitrary code on the affected system with the privileges of the targeted user.

Security readout for executives and security teams

Plain-English summary

This CVE affects Cisco Webex recording players for Windows. A malicious Webex recording file could run code on a user’s machine if the user opens it. The business risk is endpoint compromise through email or link-based social engineering, especially where old Webex player software remains installed.

Executive priority

Treat as a high-priority endpoint hygiene issue, not a broad internet-exposed emergency. Prioritize environments with heavy Webex recording use or unmanaged Windows software, and remove or update the player where found.

Technical view

The issue is improper validation of ARF and WRF recording files in Cisco Webex Network Recording Player and Cisco Webex Player for Microsoft Windows. It is classified as CWE-119 with CVSS 3.0 score 7.8. Exploitation requires local file opening by a user and runs code with that user’s privileges.

Likely exposure

Exposure is most likely on Windows endpoints with the affected Cisco Webex recording player software installed. The source bundle does not specify exact affected versions, so teams should verify installed versions against Cisco’s advisory.

Exploitation context

The documented attack path is a malicious ARF or WRF file delivered by link or email attachment, followed by persuading the user to open it. The bundle marks KEV as false and provides no cited evidence of active exploitation.

Researcher notes

Evidence supports user-assisted arbitrary code execution via malformed ARF or WRF parsing. The bundle lacks exact version ranges, patch details, and exploitation-in-the-wild evidence, so validation should anchor on Cisco’s advisory and local software inventory.

Mitigation direction

  • Check Cisco’s advisory for affected versions and fixed software guidance.
  • Update or remove affected Webex recording player software from Windows endpoints.
  • Limit opening of unsolicited ARF and WRF files from email or links.
  • Use endpoint controls to flag suspicious execution from recording player processes.

Validation and detection

  • Inventory Windows endpoints for Cisco Webex Network Recording Player or Webex Player.
  • Compare discovered versions with Cisco’s advisory for CVE-2019-1925.
  • Review email and web gateways for ARF or WRF attachments or links.
  • Check endpoint telemetry for Webex player crashes or suspicious child processes.
