Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

This vulnerability allows unauthenticated remote commands, granting direct access to the Kaseya VSA database. Attackers have exploited this to deploy ransomware on managed endpoints. Organizations with the ManagedIT.asmx page accessible via the Kaseya VSA web interface are at risk of arbitrary SQL queries, leading to potential data compromise and system control.

  • Find assets with the affected integration.
  • Restrict access to the integration's web interface.
  • Address the vulnerability and monitor systems.

Frequently asked questions

What is ConnectWise ManagedITSync for Kaseya VSA?

ConnectWise ManagedITSync is an integration component used with Kaseya VSA, a remote monitoring and management software. It facilitates synchronization and management tasks between different IT systems, allowing IT professionals to oversee and control multiple endpoints and networks efficiently. This integration is designed to streamline IT operations by connecting various management tools.

What is the weakness in CVE-2017-18362?

CVE-2017-18362 is a SQL injection vulnerability (CWE-89). This means an attacker can send specially crafted SQL commands through the ManagedIT.asmx interface to manipulate the Kaseya VSA database. This allows them to read sensitive data or execute commands without needing any authentication, potentially leading to a full compromise of the database.

How can an attacker exploit this Kaseya VSA vulnerability?

An attacker can exploit this vulnerability if the ManagedIT.asmx page is accessible via the Kaseya VSA web interface. They can then send unauthenticated SQL queries to the system. If the web interface is not exposed externally, or if the specific integration is not in use, the bug would not be triggered.

Who should be concerned about CVE-2017-18362?

Organizations using Kaseya VSA with the ConnectWise ManagedITSync integration are at risk. This vulnerability is classified as external, meaning it can be targeted over the network. If your Kaseya VSA is internet-facing, it's crucial to assess your exposure to this threat.

What is the first step for responding to this CVE?

The initial step is to identify any assets running the affected Kaseya VSA versions with the ConnectWise ManagedITSync integration. If the ManagedIT.asmx page is accessible, restrict direct access to its web interface immediately and investigate the integration's usage and security posture.
