Security readout for executives and security teams

Plain-English summary

This issue affects the Edge Gateway component of Mitel MiVoice Connect through 19.3 (22.22.6100.0). An authenticated internal attacker could abuse URL parameters to run commands. The score is medium, but CISA KEV means exploitation has been observed, raising operational urgency.

Executive priority

Treat as high priority despite a medium CVSS score because it is KEV-listed and can affect full system confidentiality, integrity, and availability.

Technical view

CVE-2022-40765 is CWE-77 command injection in Mitel MiVoice Connect Edge Gateway. The CVSS 3.1 vector is AV:A/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H, requiring adjacent/internal access and high privileges but allowing high confidentiality, integrity, and availability impact.

Likely exposure

Organizations using Mitel MiVoice Connect Edge Gateway through version 19.3 (22.22.6100.0), especially where internal users or administrators can reach affected interfaces.

Exploitation context

CISA lists this CVE in the Known Exploited Vulnerabilities catalog. The provided sources do not describe exploitation details, scale, indicators, or whether public exploit code exists.

Researcher notes

Evidence supports authenticated, internal command injection via insufficient URL parameter restrictions. The bundle does not provide patch version details, exploit indicators, or affected CPEs, so validation should lean on Mitel advisory 22-0007 and local asset data.

Mitigation direction

  • Inventory Mitel MiVoice Connect Edge Gateway deployments and record versions.
  • Prioritize systems running through 19.3 (22.22.6100.0) for remediation review.
  • Apply Mitel Product Security Advisory 22-0007 guidance or vendor-provided updates.
  • Restrict internal access to Edge Gateway management paths to trusted administrators.
  • Review authentication and administrative account exposure around affected systems.
  • Monitor logs for suspicious URL parameter activity and command execution indicators.

Validation and detection

  • Confirm whether MiVoice Connect Edge Gateway exists in the environment.
  • Verify deployed versions are not within the affected through-19.3 range.
  • Check CISA KEV tracking for required remediation timelines if applicable.
  • Review access controls limiting internal reachability to authenticated administrators.
  • Search logs for abnormal Edge Gateway URL parameter activity without replaying requests.
