ConnectWise ScreenConnect vulnerability
ConnectWise ScreenConnect authentication bypass allows network-adjacent attackers to create administrator accounts, enabling full system compromise and lateral movement.
Verdict
Today item, not a backlog item.
An authentication bypass in ScreenConnect's management interface permits unauthenticated account creation at the highest privilege level. Active exploitation and ransomware deployment confirm critical operational risk to managed service providers and their downstream clients.

Is it exploitable?
— the evidence, ranked above the scoreExploit available
Fully weaponized — public exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
662 independent public reports 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 2024-02-22), flagged for known ransomware use.
Probability (EPSS)
EPSS 0.99959 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: ConnectWise, ScreenConnect. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-288 Auth Bypass via Alternate Path — weakness family: Authentication.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 network access to the ScreenConnect management interface and exploit the authentication bypass to create a new administrator account without credentials.
Business
An attacker establishes persistent administrative access to the remote management platform, bypassing all authentication controls.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I use the newly created administrator account to authenticate and assume full control of the ScreenConnect deployment.
Business
The attacker obtains unrestricted command execution across all endpoints managed by ScreenConnect, including customer systems.
3
Lateral reach — past segmentation narrative 3
Attacker
I deploy ransomware payloads or lateral movement tools across the managed endpoint infrastructure from the compromised ScreenConnect instance.
Business
Customer environments suffer widespread encryption, data exfiltration, or supply-chain compromise through the MSP's trusted management channel.
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.
