This vulnerability is due to insufficient handling of malformed MPLS packets that are processed by a device that is running Cisco SD-WAN Software. An attacker could exploit this vulnerability by sending a crafted MPLS packet to an affected device that is running Cisco SD-WAN Software or Cisco SD-WAN vManage Software. A successful exploit could allow the attacker to gain unauthorized access to sensitive information. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
