Cisco Identity Services Engine (ISE) is widely used in corporate environments for network access control, providing secure access to corporate networks. ISE automates network enforcement for security policies across a distributed network. The platform is utilized by network administrators to enforce security policies, provide visibility, and manage compliance across wired, wireless, and VPN networks. Key functionalities include guest access, secure network access, contextual understanding, and visibility into who and what is part of the network landscape. Organizations deploy Cisco ISE to ensure that only trusted devices gain access to network resources, enhancing both security and compliance.
The unrestricted file upload vulnerability in Cisco Identity Services Engine (ISE) enables attackers to bypass security controls by uploading files without proper validation. This issue is caused by inadequate file validation in an internal API, allowing unauthenticated attackers to upload files that can be executed by the system, potentially as root. Attackers can exploit this flaw to execute arbitrary code on the server, effectively compromising the system. The vulnerability is particularly dangerous because it does not require authentication and can lead to complete control over affected systems.
The technical details of this vulnerability involve exploiting an internal API endpoint in Cisco ISE that fails to enforce proper file validation rules, allowing unauthenticated parties to upload files. The vulnerability is triggered by submitting a crafted ZIP file through a POST request to the "/admin/files-upload/" endpoint. Once the file is uploaded, due to improper checks, it can be executed in the server's context. Successful exploitation results in the execution of arbitrary code, such as a crafted shell script or executable, effectively giving attackers elevated privileges on the system.
When this vulnerability is exploited by malicious actors, it can lead to severe consequences, including unauthorized access to sensitive data and potentially full control over the system. Attackers may use this to escalate privileges, install malware, vandalize the server, or access data stored within the corporate network. These actions could cause significant operational disruptions, data breaches, and loss of user trust for the organization.
