Overview of ServiceNow Security Risks and Exploitation Techniques
This technical summary analyzes research regarding the security posture of ServiceNow environments. It highlights how adversaries can transition from an initial foothold to full tenant control by exploiting specific role-based permissions. Roles such as catalog_admin, import_admin, and sn_cmdb_editor are identified as potential vectors for privilege escalation via the execution of Glide scripts, which often run with high-level system privileges.
The research also explores methods for achieving persistence and lateral movement within the platform. By leveraging business rules and scheduled jobs, it is possible to maintain access and implement communication channels within the ServiceNow platform. Furthermore, the analysis demonstrates how a compromised cloud tenant can be used to interact with on-premise MID servers, potentially bridging security boundaries and exposing the broader IT estate to further risk.
To defend against these threats, it is critical for organizations to improve their SaaS-specific detection and response capabilities. Recommended mitigations include auditing role inheritance, implementing Adaptive Authentication policies to restrict access, and closely monitoring system tables and the ECC queue for suspicious activity or unauthorized script execution.
