CVE-2021-34719 1 Cisco 46 8101-32fh, 8101-32h, 8102-64h and 43 more 2024-02-28 7.2 HIGH 7.8 HIGH
Multiple vulnerabilities in the CLI of Cisco IOS XR Software could allow an authenticated, local attacker with a low-privileged account to elevate privileges on an affected device. For more information about these vulnerabilities, see the Details section of this advisory.
CVE-2021-34709 1 Cisco 23 8101-32fh, 8101-32h, 8102-64h and 20 more 2024-02-28 6.9 MEDIUM 6.4 MEDIUM
Multiple vulnerabilities in image verification checks of Cisco Network Convergence System (NCS) 540 Series Routers, only when running Cisco IOS XR NCS540L software images, and Cisco IOS XR Software for Cisco 8000 Series Routers could allow an authenticated, local attacker to execute arbitrary code on the underlying operating system. For more information about these vulnerabilities, see the Details section of this advisory.
CVE-2021-34728 1 Cisco 46 8101-32fh, 8101-32h, 8102-64h and 43 more 2024-02-28 7.2 HIGH 7.8 HIGH
Multiple vulnerabilities in the CLI of Cisco IOS XR Software could allow an authenticated, local attacker with a low-privileged account to elevate privileges on an affected device. For more information about these vulnerabilities, see the Details section of this advisory.
CVE-2021-34720 1 Cisco 46 8101-32fh, 8101-32h, 8102-64h and 43 more 2024-02-28 4.3 MEDIUM 8.6 HIGH
A vulnerability in the IP Service Level Agreements (IP SLA) responder and Two-Way Active Measurement Protocol (TWAMP) features of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause device packet memory to become exhausted or cause the IP SLA process to crash, resulting in a denial of service (DoS) condition. This vulnerability exists because socket creation failures are mishandled during the IP SLA and TWAMP processes. An attacker could exploit this vulnerability by sending specific IP SLA or TWAMP packets to an affected device. A successful exploit could allow the attacker to exhaust the packet memory, which will impact other processes, such as routing protocols, or crash the IP SLA process.
CVE-2021-1136 1 Cisco 7 8201, 8202, 8808 and 4 more 2024-02-28 4.6 MEDIUM 6.7 MEDIUM
Multiple vulnerabilities in Cisco Network Convergence System (NCS) 540 Series Routers, only when running Cisco IOS XR NCS540L software images, and Cisco IOS XR Software for the Cisco 8000 Series Routers could allow an authenticated, local attacker to execute unsigned code during the boot process on an affected device. For more information about these vulnerabilities, see the Details section of this advisory.
CVE-2021-1244 1 Cisco 7 8201, 8202, 8808 and 4 more 2024-02-28 4.6 MEDIUM 6.7 MEDIUM
Multiple vulnerabilities in Cisco Network Convergence System (NCS) 540 Series Routers, only when running Cisco IOS XR NCS540L software images, and Cisco IOS XR Software for the Cisco 8000 Series Routers could allow an authenticated, local attacker to execute unsigned code during the boot process on an affected device. For more information about these vulnerabilities, see the Details section of this advisory.
CVE-2021-1370 1 Cisco 7 8201, 8202, 8808 and 4 more 2024-02-28 7.2 HIGH 7.8 HIGH
A vulnerability in a CLI command of Cisco IOS XR Software for the Cisco 8000 Series Routers and Network Convergence System 540 Series Routers running NCS540L software images could allow an authenticated, local attacker to elevate their privilege to root. To exploit this vulnerability, an attacker would need to have a valid account on an affected device. The vulnerability is due to insufficient validation of command line arguments. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the prompt. A successful exploit could allow an attacker with low-level privileges to escalate their privilege level to root.
CVE-2020-3473 1 Cisco 19 8201, 8202, 8808 and 16 more 2024-02-28 7.2 HIGH 7.8 HIGH
A vulnerability in task group assignment for a specific CLI command in Cisco IOS XR Software could allow an authenticated, local CLI shell user to elevate privileges and gain full administrative control of the device. The vulnerability is due to incorrect mapping of a command to task groups within the source code. An attacker could exploit this vulnerability by first authenticating to the local CLI shell on the device and using the CLI command to bypass the task group–based checks. A successful exploit could allow the attacker to elevate privileges and perform actions on the device without authorization checks.
