Description
A vulnerability in Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker to perform path traversal attacks on the underlying operating system and read arbitrary files. To exploit this vulnerability, the attacker must have valid administrative credentials. This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected system. A successful exploit could allow the attacker to access sensitive files on the affected system.
