CVE-2021-1546: Cisco SD-WAN Software Information Disclosure Vulnerability

A vulnerability in the CLI of Cisco SD-WAN Software could allow an authenticated, local attacker to access sensitive information. This vulnerability is due to improper protections on file access through the CLI. An attacker could exploit this vulnerability by running a CLI command that targets an arbitrary file on the local system. A successful exploit could allow the attacker to return portions of an arbitrary file, possibly resulting in the disclosure of sensitive information.

CVE-2021-1616: Cisco IOS XE Software H.323 Application Level Gateway Bypass Vulnerability

A vulnerability in the H.323 application level gateway (ALG) used by the Network Address Translation (NAT) feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to bypass the ALG. This vulnerability is due to insufficient data validation of traffic that is traversing the ALG. An attacker could exploit this vulnerability by sending crafted traffic to a targeted device. A successful exploit could allow the attacker to bypass the ALG and open connections that should not be allowed to a remote device located behind the ALG. Note: This vulnerability has been publicly discussed as NAT Slipstreaming.

CVE-2021-1620: Cisco IOS and IOS XE Software IKEv2 AutoReconnect Feature Denial of Service Vulnerability

A vulnerability in the Internet Key Exchange Version 2 (IKEv2) support for the AutoReconnect feature of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to exhaust the free IP addresses from the assigned local pool. This vulnerability occurs because the code does not release the allocated IP address under certain failure conditions. An attacker could exploit this vulnerability by trying to connect to the device with a non-AnyConnect client. A successful exploit could allow the attacker to exhaust the IP addresses from the assigned local pool, which prevents users from logging in and leads to a denial of service (DoS) condition.
