Summary
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.
Risk Assessment
An unauthenticated attacker can gain full access to the VSA database, potentially leading to data theft, configuration modification, and ransomware propagation across all managed devices.
Recommendation
Immediately disable or secure access to the ManagedIT.asmx page, apply vendor patches, and check systems for ransomware infections.
Other vulnerabilities in Kaseya VSA
See all- CVE-2021-30120Critical
Kaseya VSA before 9.5.7 allows attackers to bypass the 2FA requirement. The 2FA check is enforced client-side instead of server-side and can be bypassed using a local proxy.
- CVE-2021-30116CriticalActively exploited
Kaseya VSA before 9.5.7 allows credential disclosure. The default download page (dl.asp) is unauthenticated and generates KaseyaD.ini with Agent_Guid and AgentPassword, which can be used to obtain a sessionId and bypass authentication.
- CVE-2018-20753CriticalActively exploited
Kaseya VSA RMM before R9.3 9.3.0.35, R9.4 before 9.4.0.36, and R9.5 before 9.5.0.5 allows unprivileged remote attackers to execute PowerShell payloads on all managed devices. In January 2018, attackers actively exploited this vulnerability in the wild.
