Cisco's Identity Services Engine (ISE) is widely used by network administrators for ensuring secure network access by profiling and authenticating devices. It is part of Cisco's broad suite of security tools, which help in managing endpoint security and implementing network access control. Organizations employ it to streamline and strengthen their security framework, supporting secure access across their networks. The software is typically used in corporate environments where large numbers of devices and users are consistently interacting. As part of securing an organization's network, Cisco ISE often integrates with other Cisco security products and third-party solutions. Given its critical role, any vulnerabilities within it can have wide-reaching impacts on network security.
The vulnerability detected allows unauthenticated remote attackers to execute arbitrary code on the underlying operating system of Cisco ISE. The issue stems from insufficient input validation in a specific API. By crafting a malicious API request, attackers can gain root privileges, giving them complete control over an affected system. This kind of flaw is critical as it exposes systems to potential exploitation without needing valid credentials. Due to its critical network security role, exploitation of such a vulnerability can lead both to data compromise and system downtimes.
The vulnerable endpoint is identified within a specific Cisco ISE API that fails to validate user-supplied inputs adequately. The flaw is located in how the system processes crafted API requests, allowing arbitrary payloads to be executed. Attackers can leverage this to inject and execute malicious code as the root user, effectively compromising the complete system. The interplay of network exposure and administrative privileges makes this vulnerability particularly dangerous.
Exploitation of this vulnerability can lead to full system compromise, allowing attackers to install malware, exfiltrate data, or disrupt operations. The ability to execute code as root means critical system files could be modified or destroyed. Because the vulnerability can be exploited without authentication, systems exposed to the internet are particularly vulnerable, highlighting the need for immediate remediation.
