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, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 5% 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.
