CVE-2021-34711
Estado: ModificadaMedia (5.5)—
A vulnerability in the debug shell of Cisco IP Phone software could allow an authenticated, local attacker to read any file on the device file system. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by providing crafted input to a debug shell command. A successful exploit could allow the attacker to read any file on the device file system.
