CVE-2025-20374
Estado: AnalizadaMedia (4.9)—
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.
