CVSS: 7.2EPSS: 0%CPEs: 134EXPL: 0CVE-2021-1391 – Cisco IOS and IOS XE Software Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-1391
A vulnerability in the dragonite debugger of Cisco IOS XE Software could allow an authenticated, local attacker to escalate from privilege level 15 to root privilege. The vulnerability is due to the presence of development testing and verification scripts that remained on the device. An attacker could exploit this vulnerability by bypassing the consent token mechanism with the residual scripts on the affected device. A successful exploit could allow the attacker to escalate from privilege level 15 to root privilege. Una vulnerabilidad en el depurador dragonite del Software Cisco IOS XE, podría permitir a un atacante local autenticado escalar del nivel de privilegio 15 al privilegio de root. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-XE-FSM-Yj8qJbJc • CWE-489: Active Debug Code •
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: 8.8EPSS: 0%CPEs: 2EXPL: 0CVE-2019-16009 – Cisco IOS and Cisco IOS XE Software Web UI Cross-Site Request Forgery Vulnerability
https://notcve.org/view.php?id=CVE-2019-16009
A vulnerability in the web UI of Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections for the web UI on an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the targeted user. If the user has administrative privileges, the attacker could alter the configuration, execute commands, or reload an affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200108-ios-csrf • CWE-352: Cross-Site Request Forgery (CSRF) •
CVSS: 7.7EPSS: 0%CPEs: 155EXPL: 0CVE-2020-3235 – Cisco IOS and IOS XE Software Simple Network Management Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3235
A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco IOS Software and Cisco IOS XE Software on Catalyst 4500 Series Switches could allow an authenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to insufficient input validation when the software processes specific SNMP object identifiers. An attacker could exploit this vulnerability by sending a crafted SNMP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Note: To exploit this vulnerability by using SNMPv2c or earlier, the attacker must know the SNMP read-only community string for an affected system. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snmp-dos-USxSyTk5 https://www.oracle.com/security-alerts/cpuoct2020.html • CWE-20: Improper Input Validation CWE-118: Incorrect Access of Indexable Resource ('Range Error') •
CVSS: 8.8EPSS: 0%CPEs: 91EXPL: 0CVE-2020-3234 – Cisco IOS Software for Cisco Industrial Routers Virtual Device Server Static Credentials Vulnerability
https://notcve.org/view.php?id=CVE-2020-3234
A vulnerability in the virtual console authentication of Cisco IOS Software for Cisco 809 and 829 Industrial Integrated Services Routers (Industrial ISRs) and Cisco 1000 Series Connected Grid Routers (CGR1000) could allow an authenticated but low-privileged, local attacker to log in to the Virtual Device Server (VDS) of an affected device by using a set of default credentials. The vulnerability is due to the presence of weak, hard-coded credentials. An attacker could exploit this vulnerability by authenticating to the targeted device and then connecting to VDS through the device’s virtual console by using the static credentials. A successful exploit could allow the attacker to access the Linux shell of VDS as the root user. Una vulnerabilidad en la autenticación de la consola virtual de Cisco IOS Software para Cisco 809 y 829 Industrial Integrated Services Routers (Industrial ISRs) y Cisco 1000 Series Connected Grid Routers (CGR1000), podría permitir a un atacante local autenticado pero poco privilegiado iniciar sesión en el Virtual Device Server (VDS) de un dispositivo afectado mediante el uso de un conjunto de credenciales predeterminadas. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ios-iot-vds-cred-uPMp9zbY • CWE-798: Use of Hard-coded Credentials •
