Description Preview
Multiple vulnerabilities in Cisco Identity Services Engine (ISE) could allow an authenticated attacker to perform command injection attacks on the underlying operating system and elevate privileges to root. These vulnerabilities are identified as CWE-78 (OS Command Injection) and require valid credentials on an affected device to exploit. The attacker could use these vulnerabilities to execute arbitrary commands with elevated privileges, potentially leading to complete system compromise.
Overview
This vulnerability (CVE-2023-20164) affects the Cisco Identity Services Engine (ISE), which is a security policy management platform that provides secure access to network resources. The vulnerability allows authenticated users to inject operating system commands and elevate their privileges to root level. This is particularly dangerous as it gives attackers the ability to gain complete control over the affected system, modify configurations, access sensitive data, or disrupt services. The vulnerability stems from insufficient input validation mechanisms that fail to properly sanitize user-supplied input before it's processed by the underlying operating system.
Remediation
- Update to the latest version of Cisco Identity Services Engine as recommended by Cisco in their security advisory.
- Implement proper access controls to limit who can authenticate to the ISE system.
- Monitor system logs for suspicious activities that might indicate exploitation attempts.
- Follow the principle of least privilege for all user accounts with access to the ISE system.
- Implement network segmentation to limit the impact if exploitation occurs.
- Review Cisco's security advisory for specific patch information and additional mitigation strategies.
