Description
Two vulnerabilities in Cisco ISE could allow an authenticated, remote attacker to upload arbitrary files to an affected device. To exploit these vulnerabilities, an attacker must have valid Administrator credentials on the affected device. These vulnerabilities are due to improper validation of files that are uploaded to the web-based management interface. An attacker could exploit these vulnerabilities by uploading a crafted file to an affected device. A successful exploit could allow the attacker to store malicious files in specific directories on the device. The attacker could later use those files to conduct additional attacks, including executing arbitrary code on the affected device with root privileges.
