CVE-2022-36116 in Blue Prism
Summary
by MITRE • 08/26/2022
An issue was discovered in Blue Prism Enterprise 6.0 through 7.01. In a misconfigured environment that exposes the Blue Prism Application server, it is possible for an authenticated user to reverse engineer the Blue Prism software and circumvent access controls for the setValidationInfo administrative function. Removing the validation applied to newly designed processes increases the chance of successfully hiding malicious code that could be executed in a production environment.

The vulnerability CVE-2022-36116 represents a critical access control bypass in Blue Prism Enterprise versions 6.0 through 7.01, specifically targeting the setValidationInfo administrative function within improperly configured server environments. This issue emerges when the Blue Prism Application server is exposed to unauthorized networks without proper security controls, creating an attack surface that malicious actors can exploit to undermine the platform's security architecture. The vulnerability stems from insufficient validation mechanisms that should normally protect administrative functions from unauthorized manipulation.
The technical flaw manifests through the reverse engineering capabilities available to authenticated users who can exploit the misconfigured environment to understand the internal workings of the Blue Prism software. This reverse engineering process allows attackers to identify and circumvent the validation controls that are supposed to protect the setValidationInfo administrative function. The vulnerability operates at the application layer and leverages the principle of least privilege violation, where normal user permissions are escalated to administrative capabilities through careful manipulation of the validation process. According to CWE-284, this represents an improper access control vulnerability where the system fails to properly restrict access to administrative functions.
The operational impact of this vulnerability extends far beyond simple privilege escalation, as it creates a pathway for attackers to deploy malicious code within production environments. When validation controls are removed for newly designed processes, the system becomes vulnerable to code injection attacks that can execute arbitrary commands within the Blue Prism environment. This creates a significant risk for organizations that rely on Blue Prism for automated business processes, as malicious code could potentially disrupt operations, exfiltrate sensitive data, or establish persistent backdoors within the automation infrastructure. The vulnerability particularly affects enterprise environments where process automation is critical to business operations.
Organizations should implement immediate mitigations including network segmentation to isolate Blue Prism Application servers from unauthorized network access, proper firewall configuration to restrict access to administrative ports, and regular security assessments to identify misconfigurations. The implementation of principle of least privilege should be enforced to ensure that only authorized administrators can access the setValidationInfo function. Additionally, organizations should conduct regular penetration testing and vulnerability scanning to identify similar misconfigurations that could expose other administrative functions within the Blue Prism platform. According to ATT&CK framework, this vulnerability maps to T1078 (Valid Accounts) and T1548.001 (Abuse Elevation Control Mechanism), representing the exploitation of legitimate administrative access to escalate privileges and bypass security controls.
