An attacker could exploit this vulnerability by sending a crafted HTTP request and reading the file that contains the DCA password from that affected system. A successful exploit could allow the attacker to access another affected system and gain DCA user privileges.\r\nNote: Cisco Catalyst SD-WAN Manager releases 20.18 and later are not affected by this vulnerability."
