CVE-2017-18362

ConnectWise ManagedITSync integration through 2017 for Kaseya VSA is vulnerable to unauthenticated remote commands that allow full direct access to the Kaseya VSA database. In February 2019, attackers have actively exploited this in the wild to download and execute ransomware payloads on all endpoints managed by the VSA server. If the ManagedIT.asmx page is available via the Kaseya VSA web interface, anyone with access to the page is able to run arbitrary SQL queries, both read and write, without authentication.

Fix and mitigation

WAF and other mitigations

Can a WAF block it? Yes. SQL injection puts SQL syntax into a request parameter, and WAF signatures recognise that syntax well.

Common questions

Is CVE-2017-18362 being exploited?

Yes. CVE-2017-18362 appears in CISA's Known Exploited Vulnerabilities catalog, which means exploitation in the wild has been confirmed and reported. Treat it as active rather than theoretical, and patch it ahead of higher-scoring vulnerabilities that carry no exploitation evidence.

How severe is CVE-2017-18362?

CVE-2017-18362 is rated Critical with a CVSS score of 9.8. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

Is there a patch for CVE-2017-18362?

Not known from our data. No patch reference has been recorded for CVE-2017-18362, which is not the same as no patch existing — a fix may have shipped without a tagged reference, or after this record was written. The vendor advisory is the only authority on whether a fix exists, and mitigations may be available regardless.

What does CVE-2017-18362 affect?

CVE-2017-18362 affects connectwise:manageditsync. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
