ConnectWise has issued a critical security update for its Automate platform as of Thu, Oct 16, 2025. The patch, version 2025.9, addresses significant vulnerabilities in agent communications, which could allow attackers to intercept sensitive data or introduce malicious software updates.
The vulnerabilities predominantly impact on-premises installations, particularly where systems are configured to utilize unencrypted HTTP traffic or outdated encryption protocols. Such configurations may expose systems to network-based exploits.
The vulnerabilities require adjacent network access and could lead to severe attacks without user interaction. An adversary on the same local network could potentially eavesdrop on data transmissions or tamper with update downloads, risking data breaches or full system compromise.
ConnectWise has categorized these vulnerabilities as "Important" with a moderate priority rating, indicating a need for prompt action.
ConnectWise has issued a critical security update for its Automate platform as of Thu, Oct 16, 2025.
CVE-2025-11492: Involves the cleartext transmission of sensitive information, with a CVSS base score of 9.6. CVE-2025-11493: Concerns the download of code without integrity checks, with a CVSS base score of 8.8.
Both vulnerabilities affect versions prior to 2025.9 and impact numerous IT service providers utilizing ConnectWise Automate for remote management.
For cloud-hosted instances, ConnectWise has already deployed the 2025.9 update automatically. On-premises users are required to manually apply the patch, which enforces HTTPS for all agent interactions and recommends enabling TLS 1.2 to mitigate downgrade attacks.
It is advised to conduct an audit of configurations post-update to confirm encrypted channels and monitor for unusual traffic patterns. Implementing these measures is crucial to mitigate risks in a volatile threat landscape.
