| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-02-29 | CVE-2024-20267 | Classic Buffer Overflow vulnerability in Cisco Nx-Os A vulnerability with the handling of MPLS traffic for Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause the netstack process to unexpectedly restart, which could cause the device to stop processing network traffic or to reload. | 8.6 |
| 2024-02-29 | CVE-2024-20321 | Allocation of Resources Without Limits or Throttling vulnerability in Cisco Nx-Os A vulnerability in the External Border Gateway Protocol (eBGP) implementation of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability exists because eBGP traffic is mapped to a shared hardware rate-limiter queue. | 8.6 |
| 2023-10-10 | CVE-2023-44487 | Resource Exhaustion vulnerability in multiple products The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. | 7.5 |
| 2023-08-23 | CVE-2023-20169 | Improper Input Validation vulnerability in Cisco Nx-Os 10.3(2) A vulnerability in the Intermediate System-to-Intermediate System (IS-IS) protocol of Cisco NX-OS Software for the Cisco Nexus 3000 Series Switches and Cisco Nexus 9000 Series Switches in standalone NX-OS mode could allow an unauthenticated, adjacent attacker to cause the IS-IS process to unexpectedly restart, which could cause an affected device to reload. This vulnerability is due to insufficient input validation when parsing an ingress IS-IS packet. | 7.4 |
| 2023-07-12 | CVE-2023-20185 | Inadequate Encryption Strength vulnerability in Cisco Nx-Os A vulnerability in the Cisco ACI Multi-Site CloudSec encryption feature of Cisco Nexus 9000 Series Fabric Switches in ACI mode could allow an unauthenticated, remote attacker to read or modify intersite encrypted traffic. This vulnerability is due to an issue with the implementation of the ciphers that are used by the CloudSec encryption feature on affected switches. | 7.4 |
| 2023-02-23 | CVE-2023-20050 | OS Command Injection vulnerability in Cisco Nx-Os A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system of an affected device. | 7.8 |
| 2022-02-23 | CVE-2022-20623 | Unspecified vulnerability in Cisco Nx-Os A vulnerability in the rate limiter for Bidirectional Forwarding Detection (BFD) traffic of Cisco NX-OS Software for Cisco Nexus 9000 Series Switches could allow an unauthenticated, remote attacker to cause BFD traffic to be dropped on an affected device. | 7.5 |
| 2022-02-23 | CVE-2022-20624 | Improper Input Validation vulnerability in Cisco Nx-Os A vulnerability in the Cisco Fabric Services over IP (CFSoIP) feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. | 7.5 |
| 2022-02-23 | CVE-2022-20650 | OS Command Injection vulnerability in Cisco Nx-Os 10.2(1.72)/7.3(8)N1(0.4) A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an authenticated, remote attacker to execute arbitrary commands with root privileges. | 8.8 |
| 2021-09-23 | CVE-2021-34714 | Improper Input Validation vulnerability in Cisco products A vulnerability in the Unidirectional Link Detection (UDLD) feature of Cisco FXOS Software, Cisco IOS Software, Cisco IOS XE Software, Cisco IOS XR Software, and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause an affected device to reload. | 7.4 |
