Raw vector
CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2022-40765 is a medium-severity Command Injection (CWE-77) vulnerability in Mitel Mivoice Connect. Its CVSS base score is 6.8 (Medium).
Operationally, ranked in the top 4% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
A command-injection vulnerability exists in the Edge Gateway component of Mitel MiVoice Connect releases through 19.3 (22.22.6100.0). The flaw stems from insufficient validation of URL parameters and is tracked as CWE-77. An authenticated attacker on the adjacent network can supply crafted input that results in arbitrary command execution on the affected gateway.
Successful exploitation grants the attacker full control over confidentiality, integrity, and availability of the target component. The CVSS 3.1 score of 6.8 reflects the requirement for high-privileged internal access and the absence of user interaction, yet still indicates high impact once the injection succeeds.
Mitel has published security advisory 22-0007 detailing the issue and directing customers to apply vendor-supplied updates. The vulnerability also appears in the CISA Known Exploited Vulnerabilities catalog, confirming observed exploitation in the wild.
The associated EPSS score remains low, with a recorded peak of 0.0404.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
A.8.25 mandates secure SDLC practices including secure coding guidelines, security requirements, checkpoints, testing (scans/penetration), and developer training that reduce command injection defects, but leaves a minority slice (e.g. incomplete implementation of those practices, outsourced development without full assurance, or post-SDLC changes) where the weakness can still arise and be exploitable.
Application security requirements explicitly call for controls against injection flaws including command injection.
A.8.27 mandates security-by-design principles (e.g. distrust external input, secure session control, data validation/sanitization, least privilege) and design reviews that can stop command injection from being introduced, but this is only a minority slice of CWE-77 because the weakness can still arise in code that bypasses those principles, in non-reviewed components, or in runtime injection vectors the architecture review does not reach.
Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.
Security testing in development catches command-injection vulnerabilities before release.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-77, a class-level weakness, and none of its children carries one either.
