CVSS: 7.7EPSS: 0%CPEs: 834EXPL: 0CVE-2021-34699 – Cisco IOS and IOS XE Software TrustSec CLI Parser Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-34699
A vulnerability in the TrustSec CLI parser of Cisco IOS and Cisco IOS XE Software could allow an authenticated, remote attacker to cause an affected device to reload. This vulnerability is due to an improper interaction between the web UI and the CLI parser. An attacker could exploit this vulnerability by requesting a particular CLI command to be run through the web UI. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en el analizador TrustSec CLI de Cisco IOS and Cisco IOS XE Software podría permitir a un atacante remoto y autenticado causar una recarga de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-trustsec-dos-7fuXDR2 • CWE-435: Improper Interaction Between Multiple Correctly-Behaving Entities CWE-436: Interpretation Conflict •
CVSS: 7.8EPSS: 0%CPEs: 214EXPL: 0CVE-2021-1392 – Cisco IOS and IOS XE Software Common Industrial Protocol Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-1392
A vulnerability in the CLI command permissions of Cisco IOS and Cisco IOS XE Software could allow an authenticated, local attacker to retrieve the password for Common Industrial Protocol (CIP) and then remotely configure the device as an administrative user. This vulnerability exists because incorrect permissions are associated with the show cip security CLI command. An attacker could exploit this vulnerability by issuing the command to retrieve the password for CIP on an affected device. A successful exploit could allow the attacker to reconfigure the device. Una vulnerabilidad en los permisos de comando de la CLI del Software Cisco IOS y Cisco IOS XE, podría permitir a un atacante local autenticado recuperar la contraseña para el Protocolo industrial común (CIP) y luego configurar remotamente el dispositivo como un usuario administrativo. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-XE-SAP-OPLbze68 • CWE-522: Insufficiently Protected Credentials •
CVSS: 7.5EPSS: 0%CPEs: 7EXPL: 0CVE-2021-1460 – Cisco IOx Application Framework Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1460
A vulnerability in the Cisco IOx Application Framework of Cisco 809 Industrial Integrated Services Routers (Industrial ISRs), Cisco 829 Industrial ISRs, Cisco CGR 1000 Compute Module, and Cisco IC3000 Industrial Compute Gateway could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient error handling during packet processing. An attacker could exploit this vulnerability by sending a high and sustained rate of crafted TCP traffic to the IOx web server on an affected device. A successful exploit could allow the attacker to cause the IOx web server to stop processing requests, resulting in a DoS condition. Una vulnerabilidad en el Cisco IOx Application Framework de los Enrutadores Cisco 809 Industrial Integrated Services (Industrial ISRs), Cisco 829 Industrial ISRs, Cisco CGR 1000 Compute Module, y Cisco IC3000 Industrial Compute Gateway, podría permitir a un atacante remoto no autenticado causar una denegación de servicio. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iox-dos-4Fgcjh6 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 9.8EPSS: 0%CPEs: 55EXPL: 0CVE-2021-1451 – Cisco IOS XE Software Easy Virtual Switching System Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-1451
A vulnerability in the Easy Virtual Switching System (VSS) feature of Cisco IOS XE Software for Cisco Catalyst 4500 Series Switches and Cisco Catalyst 4500-X Series Switches could allow an unauthenticated, remote attacker to execute arbitrary code on the underlying Linux operating system of an affected device. The vulnerability is due to incorrect boundary checks of certain values in Easy VSS protocol packets that are destined for an affected device. An attacker could exploit this vulnerability by sending crafted Easy VSS protocol packets to UDP port 5500 while the affected device is in a specific state. When the crafted packet is processed, a buffer overflow condition may occur. A successful exploit could allow the attacker to trigger a denial of service (DoS) condition or execute arbitrary code with root privileges on the underlying Linux operating system of the affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-xe-evss-code-exe-8cw5VSvw • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.8EPSS: 0%CPEs: 224EXPL: 0CVE-2021-1442 – Cisco IOS XE Software Plug-and-Play Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-1442
A vulnerability in a diagnostic command for the Plug-and-Play (PnP) subsystem of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to the level of an Administrator user (level 15) on an affected device. The vulnerability is due to insufficient protection of sensitive information. An attacker with low privileges could exploit this vulnerability by issuing the diagnostic CLI show pnp profile when a specific PnP listener is enabled on the device. A successful exploit could allow the attacker to obtain a privileged authentication token. This token can be used to send crafted PnP messages and execute privileged commands on the targeted system. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-xe-pnp-priv-esc-AmG3kuVL • CWE-532: Insertion of Sensitive Information into Log File •
