| CVE-2020-3396 | 1 Cisco | 56 1100-4g Integrated Services Router, 1100-4gltegb Integrated Services Router, 1100-4gltena Integrated Services Router and 53 more | 2024-11-21 | 6.9 MEDIUM | 6.8 MEDIUM |
| A vulnerability in the file system on the pluggable USB 3.0 Solid State Drive (SSD) for Cisco IOS XE Software could allow an authenticated, physical attacker to remove the USB 3.0 SSD and modify sensitive areas of the file system, including the namespace container protections. The vulnerability occurs because the USB 3.0 SSD control data is not stored on the internal boot flash. An attacker could exploit this vulnerability by removing the USB 3.0 SSD, modifying or deleting files on the USB 3.0 SSD by using another device, and then reinserting the USB 3.0 SSD on the original device. A successful exploit could allow the attacker to remove container protections and perform file actions outside the namespace of the container with root privileges. | |||||
| CVE-2020-3393 | 1 Cisco | 128 1100-4g Integrated Services Router, 1100-4gltegb Integrated Services Router, 1100-4gltena Integrated Services Router and 125 more | 2024-11-21 | 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. | |||||
