CVE-2022-2013 in Server
Summary
by MITRE • 06/13/2022
In Octopus Server after version 2022.1.1495 and before 2022.1.2647 if private spaces were enabled via the experimental feature flag all new users would have access to the Script Console within their private space.

This vulnerability exists within the Octopus Server platform affecting versions between 2022.1.1495 and 2022.1.2647 where the implementation of private spaces contains a critical access control flaw. The issue arises when administrators enable private spaces through an experimental feature flag, creating a privilege escalation scenario that allows unauthorized users to gain access to the Script Console functionality within their private spaces. This represents a significant security weakness in the platform's authorization model and could potentially enable malicious actors to execute arbitrary code or access sensitive system resources.
The technical flaw stems from improper access control implementation where the system fails to properly restrict Script Console access based on user permissions and roles. When private spaces are enabled, the system incorrectly grants Script Console privileges to all new users regardless of their actual authorization level or role within the organization. This misconfiguration creates a path for privilege escalation and could allow attackers to execute malicious scripts, potentially leading to system compromise or data exfiltration. The vulnerability is classified as a weakness in access control mechanisms and aligns with CWE-285 which addresses insufficient authorization in software systems.
The operational impact of this vulnerability is substantial as it could enable attackers to gain unauthorized access to critical system functionality. The Script Console represents a powerful administrative tool that allows execution of arbitrary code, making it a prime target for exploitation. Attackers could leverage this vulnerability to escalate privileges, execute malicious payloads, or perform other unauthorized actions within the private spaces they have access to. This vulnerability undermines the security model of private spaces, which are designed to isolate and protect sensitive operations from unauthorized access. The exposure could lead to complete system compromise if attackers can leverage the Script Console to gain further access to system resources or data.
Organizations using affected Octopus Server versions should immediately update to version 2022.1.2647 or later where this vulnerability has been patched. System administrators should also review current access control policies and ensure that experimental feature flags are not enabled in production environments without proper security review. The mitigation strategy should include disabling private spaces feature flag until proper access controls are implemented and tested. Additionally, organizations should conduct security audits of their Octopus Server configurations to identify any other potential access control issues and implement proper monitoring for unauthorized access attempts. This vulnerability demonstrates the importance of proper access control implementation and the risks associated with experimental features that may not undergo full security testing before deployment. The issue aligns with ATT&CK technique T1059 which covers execution through script interpreters and highlights the critical need for proper privilege management in automation platforms.
