| CVE-2020-3390 | 1 Cisco | 7 Catalyst 9800-40, Catalyst 9800-80, Catalyst 9800-cl and 4 more | 2024-12-19 | 5.7 MEDIUM | 7.4 HIGH |
| A vulnerability in Simple Network Management Protocol (SNMP) trap generation for wireless clients of the Cisco IOS XE Wireless Controller Software for the Cisco Catalyst 9000 Family could allow an unauthenticated, adjacent attacker to cause the device to unexpectedly reload, causing a denial of service (DoS) condition on an affected device. The vulnerability is due to the lack of input validation of the information used to generate an SNMP trap in relation to a wireless client connection. An attacker could exploit this vulnerability by sending an 802.1x packet with crafted parameters during the wireless authentication setup phase of a connection. A successful exploit could allow the attacker to cause the device to reload, causing a DoS condition. | |||||
| CVE-2020-3503 | 1 Cisco | 128 1100-4g Integrated Services Router, 1100-4gltegb Integrated Services Router, 1100-4gltena Integrated Services Router and 125 more | 2024-12-19 | 3.6 LOW | 6.0 MEDIUM |
| A vulnerability in the file system permissions of Cisco IOS XE Software could allow an authenticated, local attacker to obtain read and write access to critical configuration or system files. The vulnerability is due to insufficient file system permissions on an affected device. An attacker could exploit this vulnerability by connecting to an affected device's guest shell, and accessing or modifying restricted files. A successful exploit could allow the attacker to view or modify restricted information or configurations that are normally not accessible to system administrators. | |||||
| CVE-2020-3393 | 1 Cisco | 128 1100-4g Integrated Services Router, 1100-4gltegb Integrated Services Router, 1100-4gltena Integrated Services Router and 125 more | 2024-12-19 | 7.2 HIGH | 6.0 MEDIUM |
| 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. | |||||
| CVE-2020-3359 | 1 Cisco | 15 2610xm, 2611xm, 2612 and 12 more | 2024-12-19 | 7.8 HIGH | 8.6 HIGH |
| A vulnerability in the multicast DNS (mDNS) feature of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to improper validation of mDNS packets. An attacker could exploit this vulnerability by sending a crafted mDNS packet to an affected device. A successful exploit could cause a device to reload, resulting in a DoS condition. | |||||
| CVE-2021-1223 | 2 Cisco, Snort | 19 1100-4p Integrated Services Router, 1100-8p Integrated Services Router, 1101-4p Integrated Services Router and 16 more | 2024-11-26 | 5.0 MEDIUM | 7.5 HIGH |
| Multiple Cisco products are affected by a vulnerability in 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 handling of an HTTP range header. An attacker could exploit this vulnerability by sending crafted HTTP packets through an affected device. A successful exploit could allow the attacker to bypass configured file policy for HTTP packets and deliver a malicious payload. | |||||
