An attacker could exploit this vulnerability by uploading a crafted file to the affected system. A successful exploit could allow the attacker to perform command injection attacks on an affected system and elevate their privileges as the root user.\r\nTo exploit this vulnerability, the attacker must have netadmin privileges on the affected system. This would require valid credentials or exploitation of  or . Cisco is not aware of successful exploitation by other methods.
