Mitel MiVoice Connect vulnerability
Mitel MiVoice Connect Edge Gateway allows authenticated internal attackers to execute arbitrary commands with system privileges.
Verdict
Today item, not a backlog item.
An authenticated attacker with internal network access can execute commands on the Mitel Edge Gateway component, potentially compromising voice infrastructure and enabling lateral movement within enterprise networks.
01
Is it exploitable?
— the evidence, ranked above the scoreReported exploitation
1 independent public report of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2023-02-21), flagged for known ransomware use.
Probability (EPSS)
EPSS 0.10481 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Mitel, MiVoice Connect. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-77 Command Injection — weakness family: Injection.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I gain initial access as an authenticated user within the target network.
Business
Internal user credentials are compromised or an insider threat exists.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I identify and target the Mitel Edge Gateway component of MiVoice Connect.
Business
Voice and unified communications infrastructure becomes a viable attack surface.
3
Lateral reach — past segmentation narrative 3
Attacker
I exploit the command execution vulnerability to run arbitrary commands with system context.
Business
Attacker gains system-level control of critical communications infrastructure.
4
Data at risk — exfiltration narrative 4
Attacker
I establish persistence and move laterally through the network using compromised gateway access.
Business
Enterprise communications are disrupted and sensitive call data may be intercepted or exfiltrated.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
