Mitel MiVoice Connect vulnerability
The Director component in Mitel MiVoice Connect allows authenticated attackers with internal network access to execute arbitrary code, enabling lateral movement and system compromise within enterprise communications infrastructure.
Verdict
Today item, not a backlog item.
An authenticated internal attacker can execute code in the MiVoice Connect Director component. This vulnerability has been exploited in ransomware campaigns, allowing attackers to establish persistence and move laterally through affected organizations' 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 0.10571 — 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-94 Code 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 to the internal network through compromised credentials or a prior breach.
Business
Internal network perimeter is compromised, enabling lateral movement across critical communications systems.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I authenticate to MiVoice Connect using valid credentials and exploit the Director component to execute arbitrary code.
Business
Communications infrastructure is directly compromised, allowing attackers to control or monitor enterprise voice systems.
3
Lateral reach — past segmentation narrative 3
Attacker
I establish persistence and pivot to other systems on the network using the compromised MiVoice Connect instance.
Business
Attackers gain foothold for ransomware deployment and data exfiltration across the organization.
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.
