| A vulnerability in the Virtual Shell (VSH) session management for Cisco NX-OS Software could allow an authenticated, remote attacker to cause a VSH process to fail to delete upon termination. This can lead to a build-up of VSH processes that overtime can deplete system memory. When there is no system memory available, this can cause unexpected system behaviors and crashes. The vulnerability is due to the VSH process not being properly deleted when a remote management connection to the device is disconnected. An attacker could exploit this vulnerability by repeatedly performing a remote management connection to the device and terminating the connection in an unexpected manner. A successful exploit could allow the attacker to cause the VSH processes to fail to delete, which can lead to a system-wide denial of service (DoS) condition. The attacker must have valid user credentials to log in to the device using the remote management connection. | |||||
| CVE-2019-1966 | 1 Cisco | 8 Nx-os, Ucs 6248 Up Fabric Interconnect, Ucs 6296 Up Fabric Interconnect and 5 more | 2020-10-16 | 7.2 HIGH | 7.8 HIGH |
| A vulnerability in a specific CLI command within the local management (local-mgmt) context for Cisco UCS Fabric Interconnect Software could allow an authenticated, local attacker to gain elevated privileges as the root user on an affected device. The vulnerability is due to extraneous subcommand options present for a specific CLI command within the local-mgmt context. An attacker could exploit this vulnerability by authenticating to an affected device, entering the local-mgmt context, and issuing a specific CLI command and submitting user input. A successful exploit could allow the attacker to execute arbitrary operating system commands as root on an affected device. The attacker would need to have valid user credentials for the device. | |||||

| A vulnerability in the Network Time Protocol (NTP) feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to excessive use of system resources when the affected device is logging a drop action for received MODE_PRIVATE (Mode 7) NTP packets. An attacker could exploit this vulnerability by flooding the device with a steady stream of Mode 7 NTP packets. A successful exploit could allow the attacker to cause high CPU and memory usage on the affected device, which could cause internal system processes to restart or cause the affected device to unexpectedly reload. Note: The NTP feature is enabled by default. | |||||
| CVE-2020-3508 | 1 Cisco | 141 1000v, Asr 1000, Asr 1000-x and 138 more | 2020-10-16 | 6.1 MEDIUM | 7.4 HIGH |
| A vulnerability in the IP Address Resolution Protocol (ARP) feature of Cisco IOS XE Software for Cisco ASR 1000 Series Aggregation Services Routers with a 20-Gbps Embedded Services Processor (ESP) installed could allow an unauthenticated, adjacent attacker to cause an affected device to reload, resulting in a denial of service condition. The vulnerability is due to insufficient error handling when an affected device has reached platform limitations. An attacker could exploit this vulnerability by sending a malicious series of IP ARP messages to an affected device. A successful exploit could allow the attacker to exhaust system resources, which would eventually cause the affected device to reload. | |||||
| CVE-2019-15956 | 1 Cisco | 2 Asyncos, Web Security Appliance | 2020-10-16 | 6.5 MEDIUM | 8.8 HIGH |
| A vulnerability in the web management interface of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to perform an unauthorized system reset on an affected device. The vulnerability is due to improper authorization controls for a specific URL in the web management interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could have a twofold impact: the attacker could either change the administrator password, gaining privileged access, or reset the network configuration details, causing a denial of service (DoS) condition. In both scenarios, manual intervention is required to restore normal operations. | |||||
| CVE-2019-1634 | 1 Cisco | 13 Encs 5100, Encs 5400, Integrated Management Controller Supervisor and 10 more | 2020-10-16 | 9.0 HIGH | 7.2 HIGH |
| A vulnerability in the Intelligent Platform Management Interface (IPMI) of Cisco Integrated Management Controller (IMC) could allow an authenticated, remote attacker to inject arbitrary commands that are executed with root privileges on the underlying operating system (OS). The vulnerability is due to insufficient input validation of user-supplied commands. An attacker who has administrator privileges and access to the network where the IPMI resides could exploit this vulnerability by submitting crafted input to the affected commands. A successful exploit could allow the attacker to gain root privileges on the affected device. | |||||
| CVE-2019-1654 | 1 Cisco | 6 Aironet 1540, Aironet 1560, Aironet 1800 and 3 more | 2020-10-16 | 7.2 HIGH | 7.8 HIGH |
| A vulnerability in the development shell (devshell) authentication for Cisco Aironet Series Access Points (APs) running the Cisco AP-COS operating system could allow an authenticated, local attacker to access the development shell without proper authentication, which allows for root access to the underlying Linux OS. The attacker would need valid device credentials. The vulnerability exists because the software improperly validates user-supplied input at the CLI authentication prompt for development shell access. An attacker could exploit this vulnerability by authenticating to the device and entering crafted input at the CLI. A successful exploit could allow the attacker to access the AP development shell without proper authentication, which allows for root access to the underlying Linux OS. Software versions prior to 8.3.150.0, 8.5.135.0, and 8.8.100.0 are affected. | |||||
