Kaseya Virtual System/Server Administrator (VSA) vulnerability
Kaseya VSA contains an unauthenticated SQL injection vulnerability in the ConnectWise ManagedITSync integration, enabling direct database access and remote command execution.
Verdict
Today item, not a backlog item.
An unauthenticated attacker can exploit SQL injection to bypass authentication, access the VSA database directly, and execute arbitrary commands with system privileges. This vulnerability has been actively exploited in ransomware campaigns.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Public proof-of-concept exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
12 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 2022-05-24), flagged for known ransomware use.
Probability (EPSS)
EPSS 0.86706 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Kaseya, Virtual System/Server Administrator (VSA). Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-89 SQL 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 identify the ConnectWise ManagedITSync integration endpoint as unauthenticated and injectable.
Business
Attackers gain unrestricted access to the management platform without credentials.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I craft SQL injection payloads to query and extract sensitive data from the VSA database.
Business
Customer credentials, configurations, and managed systems are exposed to the attacker.
3
Lateral reach — past segmentation narrative 3
Attacker
I escalate from database access to remote command execution on the VSA server.
Business
The attacker achieves full control of the management infrastructure.
4
Data at risk — exfiltration narrative 4
Attacker
I use VSA access to deploy malware across all managed endpoints in the customer environment.
Business
Entire client networks become compromised, enabling ransomware deployment at scale.
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.
