CVE-2022-41223 — Mitel MiVoice Connect Code Injection Vulnerability
The Director database component of MiVoice Connect through 19.3 (22.22.6100.0) could allow an authenticated attacker to conduct a code-injection attack via crafted data due to insufficient restrictions on the database data type.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- Confirmed exploitation (CISA KEV)+35
- Used in ransomware campaigns (CISA)+10
- EPSS 10.7% (30-day exploitation probability)+14
- Technical severity (medium)+3
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
CISA required action CISA
Apply updates per vendor instructions.

First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Mitel Mivoice Connect).
- Treat as emergency remediation: the CVE is in CISA KEV (confirmed exploitation).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- EPSS ahead of 96% of scored CVEs: prioritize it in the patch queue.
- Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.

CISA KEV details CISA
CISA lists a CVE once it has evidence of exploitation against real targets.
CISA records ransomware use only for campaigns it has confirmed, so “Unknown” means unrecorded, not ruled out. The deadline binds US federal agencies; for everyone else it is a reference date.

Detection
Read off the CVSS vector and the weakness class. Starting points, not tested rules.
- Look for parameters with command/query metacharacters and unexpected child processes of the service.
- Hunt retroactively in logs from before Feb 21, 2023 (KEV listing): exploitation may have started earlier.

What should defenders know first?
CVE-2022-41223 is "Mitel MiVoice Connect Code Injection Vulnerability", rated Medium. It affects Mivoice Connect (Mitel); versions are in the scope table. It is in CISA KEV: there is evidence of real-world exploitation. CVSS 6.8 describes technical severity. EPSS 10.66% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
