| CVE-2020-3408 | 1 Cisco | 129 Asr1001-hx, Asr1001-hx-rf, Asr1001-x-rf and 126 more | 2022-10-27 | 7.8 HIGH | 8.6 HIGH |
| A vulnerability in the Split DNS feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability occurs because the regular expression (regex) engine that is used with the Split DNS feature of affected releases may time out when it processes the DNS name list configuration. An attacker could exploit this vulnerability by trying to resolve an address or hostname that the affected device handles. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. | |||||
| CVE-2020-3407 | 1 Cisco | 128 Asr1001-hx, Asr1001-hx-rf, Asr1001-x-rf and 125 more | 2022-10-27 | 7.1 HIGH | 8.6 HIGH |
| A vulnerability in the RESTCONF and NETCONF-YANG access control list (ACL) function of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause the device to reload. The vulnerability is due to incorrect processing of the ACL that is tied to the RESTCONF or NETCONF-YANG feature. An attacker could exploit this vulnerability by accessing the device using RESTCONF or NETCONF-YANG. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition. | |||||
| CVE-2022-20944 | 1 Cisco | 20 Catalyst 9200, Catalyst 9200cx, Catalyst 9200l and 17 more | 2022-10-13 | N/A | 6.8 MEDIUM |
| A vulnerability in the software image verification functionality of Cisco IOS XE Software for Cisco Catalyst 9200 Series Switches could allow an unauthenticated, physical attacker to execute unsigned code at system boot time. This vulnerability is due to an improper check in the code function that manages the verification of the digital signatures of system image files during the initial boot process. An attacker could exploit this vulnerability by loading unsigned software on an affected device. A successful exploit could allow the attacker to boot a malicious software image or execute unsigned code and bypass the image verification check part of the boot process of the affected device. To exploit this vulnerability, the attacker needs either unauthenticated physical access to the device or privileged access to the root shell on the device. Note: In Cisco IOS XE Software releases 16.11.1 and later, root shell access is protected by the Consent Token mechanism. However, an attacker with level-15 privileges could easily downgrade the Cisco IOS XE Software running on a device to a release where root shell access is more readily available. | |||||
| CVE-2022-20864 | 1 Cisco | 240 Catalyst 3650, Catalyst 3650-12x48fd-e, Catalyst 3650-12x48fd-l and 237 more | 2022-10-13 | N/A | 4.6 MEDIUM |
| A vulnerability in the password-recovery disable feature of Cisco IOS XE ROM Monitor (ROMMON) Software for Cisco Catalyst Switches could allow an unauthenticated, local attacker to recover the configuration or reset the enable password. This vulnerability is due to a problem with the file and boot variable permissions in ROMMON. An attacker could exploit this vulnerability by rebooting the switch into ROMMON and entering specific commands through the console. A successful exploit could allow the attacker to read any file or reset the enable password. | |||||

| CVE-2020-3214 | 1 Cisco | 106 Asr 1000-x, Asr 1001, Asr 1001-x and 103 more | 2021-09-17 | 7.2 HIGH | 6.7 MEDIUM |
| A vulnerability in Cisco IOS XE Software could allow an authenticated, local attacker to escalate their privileges to a user with root-level privileges. The vulnerability is due to insufficient validation of user-supplied content. This vulnerability could allow an attacker to load malicious software onto an affected device. | |||||
| CVE-2020-3393 | 1 Cisco | 128 Asr1001-hx, Asr1001-hx-rf, Asr1001-x-rf and 125 more | 2021-08-06 | 7.2 HIGH | 7.8 HIGH |
| A vulnerability in the application-hosting subsystem of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to root on an affected device. The attacker could execute IOS XE commands outside the application-hosting subsystem Docker container as well as on the underlying Linux operating system. These commands could be run as the root user. The vulnerability is due to a combination of two factors: (a) incomplete input validation of the user payload of CLI commands, and (b) improper role-based access control (RBAC) when commands are issued at the command line within the application-hosting subsystem. An attacker could exploit this vulnerability by using a CLI command with crafted user input. A successful exploit could allow the lower-privileged attacker to execute arbitrary CLI commands with root privileges. The attacker would need valid user credentials to exploit this vulnerability. | |||||

| A vulnerability in the Umbrella Connector component of Cisco IOS XE Software for Cisco Catalyst 9200 Series Switches could allow an unauthenticated, remote attacker to trigger a reload, resulting in a denial of service condition on an affected device. The vulnerability is due to insufficient error handling when parsing DNS requests. An attacker could exploit this vulnerability by sending a series of malicious DNS requests to an Umbrella Connector client interface of an affected device. A successful exploit could allow the attacker to cause a crash of the iosd process, which triggers a reload of the affected device. | |||||

| A vulnerability in the PROFINET handler for Link Layer Discovery Protocol (LLDP) messages of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a crash on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of LLDP messages in the PROFINET LLDP message handler. An attacker could exploit this vulnerability by sending a malicious LLDP message to an affected device. A successful exploit could allow the attacker to cause the affected device to reload. | |||||
| CVE-2020-3527 | 1 Cisco | 13 Catalyst C9200l-24p-4g, Catalyst C9200l-24p-4x, Catalyst C9200l-24pxg-2y and 10 more | 2020-10-06 | 7.8 HIGH | 8.6 HIGH |
| A vulnerability in the Polaris kernel of Cisco Catalyst 9200 Series Switches could allow an unauthenticated, remote attacker to crash the device. The vulnerability is due to insufficient packet size validation. An attacker could exploit this vulnerability by sending jumbo frames or frames larger than the configured MTU size to the management interface of this device. A successful exploit could allow the attacker to crash the device fully before an automatic recovery. | |||||
| CVE-2020-3404 | 1 Cisco | 128 Asr1001-hx, Asr1001-hx-rf, Asr1001-x-rf and 125 more | 2020-10-06 | 7.2 HIGH | 7.8 HIGH |
| A vulnerability in the persistent Telnet/Secure Shell (SSH) CLI of Cisco IOS XE Software could allow an authenticated, local attacker to gain shell access on an affected device and execute commands on the underlying operating system (OS) with root privileges. The vulnerability is due to insufficient enforcement of the consent token in authorizing shell access. An attacker could exploit this vulnerability by authenticating to the persistent Telnet/SSH CLI on an affected device and requesting shell access. A successful exploit could allow the attacker to gain shell access on the affected device and execute commands on the underlying OS with root privileges. | |||||
| CVE-2020-3207 | 1 Cisco | 56 Catalyst 3650-12x48uq, Catalyst 3650-12x48ur, Catalyst 3650-12x48uz and 53 more | 2020-06-05 | 7.2 HIGH | 6.7 MEDIUM |
| A vulnerability in the processing of boot options of specific Cisco IOS XE Software switches could allow an authenticated, local attacker with root shell access to the underlying operating system (OS) to conduct a command injection attack during device boot. This vulnerability is due to insufficient input validation checks while processing boot options. An attacker could exploit this vulnerability by modifying device boot options to execute attacker-provided code. A successful exploit may allow an attacker to bypass the Secure Boot process and execute malicious code on an affected device with root-level privileges. | |||||
