CVE-2009-0627 1 Cisco 3 Nexus 5000, Nexus 7000, Nx-os 2025-04-09 7.8 HIGH N/A
Unspecified vulnerability in Cisco NX-OS before 4.0(1a)N2(1), when running on Nexus 5000 platforms, allows remote attackers to cause a denial of service (crash) via an unspecified "sequence of TCP packets" related to "TCP State manipulation," possibly related to separate attacks against CVE-2008-4609.
CVE-2024-20321 1 Cisco 1 Nx-os 2024-11-21 N/A 8.6 HIGH
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. An attacker could exploit this vulnerability by sending large amounts of network traffic with certain characteristics through an affected device. A successful exploit could allow the attacker to cause eBGP neighbor sessions to be dropped, leading to a DoS condition in the network.
CVE-2024-20267 1 Cisco 1 Nx-os 2024-11-21 N/A 8.6 HIGH
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. This vulnerability is due to lack of proper error checking when processing an ingress MPLS frame. An attacker could exploit this vulnerability by sending a crafted IPv6 packet that is encapsulated within an MPLS frame to an MPLS-enabled interface of the targeted device. A successful exploit could allow the attacker to cause a denial of service (DoS) condition. Note: The IPv6 packet can be generated multiple hops away from the targeted device and then encapsulated within MPLS. The DoS condition may occur when the NX-OS device processes the packet.
CVE-2023-20185 1 Cisco 2 Nexus 9000 In Aci Mode, Nx-os 2024-11-21 N/A 7.4 HIGH
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. An attacker with an on-path position between the ACI sites could exploit this vulnerability by intercepting intersite encrypted traffic and using cryptanalytic techniques to break the encryption. A successful exploit could allow the attacker to read or modify the traffic that is transmitted between the sites. Cisco has not released and will not release software updates that address this vulnerability.
