Medium
4.9/10

Summary

A vulnerability in the web UI of Cisco Unified CCX could allow an authenticated, remote attacker to perform a directory traversal and access arbitrary resources. This vulnerability is due to an insufficient input validation associated to specific UI features. An attacker could exploit this vulnerability by sending a crafted request to the web UI. A successful exploit could allow the attacker to gain read access to arbitrary files on the underlying operating system. To exploit this vulnerability, the attacker must have valid administrative credentials.

CWE-22 - Path Traversal

Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
