CVE-2021-27853 3 Cisco, Ieee, Ietf 308 Catalyst 3650-12x48fd-e, Catalyst 3650-12x48fd-l, Catalyst 3650-12x48fd-s and 305 more 2022-11-16 N/A 4.7 MEDIUM
Layer 2 network filtering capabilities such as IPv6 RA guard or ARP inspection can be bypassed using combinations of VLAN 0 headers and LLC/SNAP headers.
CVE-2022-20919 1 Cisco 305 Asr-920-10sz-pd, Asr-920-12cz-a, Asr-920-12cz-d and 302 more 2022-10-27 N/A 7.5 HIGH
A vulnerability in the processing of malformed Common Industrial Protocol (CIP) packets that are sent to Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to unexpectedly reload, resulting in a denial of service (DoS) condition. This vulnerability is due to insufficient input validation during processing of CIP packets. An attacker could exploit this vulnerability by sending a malformed CIP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to unexpectedly reload, resulting in a DoS condition.
CVE-2022-20851 1 Cisco 259 8101-32fh, 8101-32h, 8102-64h and 256 more 2022-10-27 N/A 7.2 HIGH
A vulnerability in the web UI feature of Cisco IOS XE Software could allow an authenticated, remote attacker to perform an injection attack against an affected device. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted input to the web UI API. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with root privileges. To exploit this vulnerability, an attacker must have valid Administrator privileges on the affected device.
CVE-2022-20848 1 Cisco 360 8101-32fh, 8101-32h, 8102-64h and 357 more 2022-10-27 N/A 7.5 HIGH
A vulnerability in the UDP processing functionality of Cisco IOS XE Software for Embedded Wireless Controllers on Catalyst 9100 Series Access Points could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. This vulnerability is due to the improper processing of UDP datagrams. An attacker could exploit this vulnerability by sending malicious UDP datagrams to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a 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.
