| CVE-2021-34703 | 1 Cisco | 203 Catalyst 3650-12x48fd-e, Catalyst 3650-12x48fd-l, Catalyst 3650-12x48fd-s and 200 more | 2021-10-25 | 6.8 MEDIUM | 6.5 MEDIUM |
| A vulnerability in the Link Layer Discovery Protocol (LLDP) message parser of Cisco IOS Software and Cisco IOS XE Software could allow an attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. This vulnerability is due to improper initialization of a buffer. An attacker could exploit this vulnerability via any of the following methods: An authenticated, remote attacker could access the LLDP neighbor table via either the CLI or SNMP while the device is in a specific state. An unauthenticated, adjacent attacker could corrupt the LLDP neighbor table by injecting specific LLDP frames into the network and then waiting for an administrator of the device or a network management system (NMS) managing the device to retrieve the LLDP neighbor table of the device via either the CLI or SNMP. An authenticated, adjacent attacker with SNMP read-only credentials or low privileges on the device CLI could corrupt the LLDP neighbor table by injecting specific LLDP frames into the network and then accessing the LLDP neighbor table via either the CLI or SNMP. A successful exploit could allow the attacker to cause the affected device to crash, resulting in a reload of the device. | |||||
| CVE-2021-34725 | 1 Cisco | 49 Asr 1000, Asr 1000-esp100, Asr 1000-x and 46 more | 2021-10-13 | 7.2 HIGH | 6.7 MEDIUM |
| A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to inject arbitrary commands to be executed with root-level privileges on the underlying operating system. This vulnerability is due to insufficient input validation on certain CLI commands. An attacker could exploit this vulnerability by authenticating to an affected device and submitting crafted input to the CLI. The attacker must be authenticated as an administrative user to execute the affected commands. A successful exploit could allow the attacker to execute commands with root-level privileges. | |||||
| CVE-2021-34724 | 1 Cisco | 49 Asr 1000, Asr 1000-esp100, Asr 1000-x and 46 more | 2021-10-13 | 6.6 MEDIUM | 6.0 MEDIUM |
| A vulnerability in the Cisco IOS XE SD-WAN Software CLI could allow an authenticated, local attacker to elevate privileges and execute arbitrary code on the underlying operating system as the root user. An attacker must be authenticated on an affected device as a PRIV15 user. This vulnerability is due to insufficient file system protection and the presence of a sensitive file in the bootflash directory on an affected device. An attacker could exploit this vulnerability by overwriting an installer file stored in the bootflash directory with arbitrary commands that can be executed with root-level privileges. A successful exploit could allow the attacker to read and write changes to the configuration database on the affected device. | |||||
| CVE-2021-34723 | 1 Cisco | 21 Asr 1000-x, Asr 1001, Asr 1001-x and 18 more | 2021-09-30 | 6.9 MEDIUM | 6.7 MEDIUM |
| A vulnerability in a specific CLI command that is run on Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to overwrite arbitrary files in the configuration database of an affected device. This vulnerability is due to insufficient validation of specific CLI command parameters. An attacker could exploit this vulnerability by issuing that command with specific parameters. A successful exploit could allow the attacker to overwrite the content of the configuration database and gain root-level access to an affected device. | |||||
| CVE-2021-1371 | 1 Cisco | 17 Asr 1000, Cloud Services Router 1000v, Ios Xe Sd-wan and 14 more | 2021-03-31 | 7.2 HIGH | 6.6 MEDIUM |
| A vulnerability in the role-based access control of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker with read-only privileges to obtain administrative privileges by using the console port when the device is in the default SD-WAN configuration. This vulnerability occurs because the default configuration is applied for console authentication and authorization. An attacker could exploit this vulnerability by connecting to the console port and authenticating as a read-only user. A successful exploit could allow a user with read-only permissions to access administrative privileges. | |||||
| CVE-2021-1236 | 2 Cisco, Snort | 19 Csr 1000v, Firepower Management Center, Firepower Threat Defense and 16 more | 2021-01-19 | 5.0 MEDIUM | 5.3 MEDIUM |
| Multiple Cisco products are affected by a vulnerability in the Snort application detection engine that could allow an unauthenticated, remote attacker to bypass the configured policies on an affected system. The vulnerability is due to a flaw in the detection algorithm. An attacker could exploit this vulnerability by sending crafted packets that would flow through an affected system. A successful exploit could allow the attacker to bypass the configured policies and deliver a malicious payload to the protected network. | |||||
| CVE-2021-1224 | 2 Cisco, Snort | 43 Csr 1000v, Firepower Management Center, Firepower Threat Defense and 40 more | 2021-01-19 | 5.0 MEDIUM | 5.3 MEDIUM |
| Multiple Cisco products are affected by a vulnerability with TCP Fast Open (TFO) when used in conjunction with the Snort detection engine that could allow an unauthenticated, remote attacker to bypass a configured file policy for HTTP. The vulnerability is due to incorrect detection of the HTTP payload if it is contained at least partially within the TFO connection handshake. An attacker could exploit this vulnerability by sending crafted TFO packets with an HTTP payload through an affected device. A successful exploit could allow the attacker to bypass configured file policy for HTTP packets and deliver a malicious payload. | |||||
