An attacker could exploit this vulnerability by sending crafted IP traffic through an affected device, which may cause a buffer overflow when the traffic is processed. A successful exploit could allow the attacker to execute arbitrary code on the underlying operating system with root privileges.\r\n\r\nCisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.\r\n\r\nBug ID(s): CSCvt11525 [\"https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvt11525\"]\r\nCVE ID: CVE-2021-1300\r\nSecurity Impact Rating (SIR): High\r\nCVSS Base Score: 9.8\r\nCVSS Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H\r\n\r\nCVE-2021-1301: Cisco SD-WAN Buffer Overflow Vulnerability\r\n\r\nA vulnerability in the NETCONF subsystem of Cisco SD-WAN Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device or system.\r\n\r\nThe vulnerability is due to insufficient input validation of user-supplied input that is read by the system during the establishment of an SSH connection. An attacker could exploit this vulnerability by submitting a crafted file to be read by the affected system. A successful exploit could allow the attacker to cause a buffer overflow that could result in a DoS condition on the affected device or system.\r\n\r\nCisco has released software updates that address this vulnerability.

If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.\r\n  Customers Without Service Contracts\r\nCustomers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC: https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html [\"https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html\"]\r\n\r\nCustomers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade.\r\n      Fixed Releases\r\nCustomers are advised to upgrade to an appropriate fixed software release as indicated in the following table(s).
