CVSS: 7.2EPSS: 0%CPEs: 74EXPL: 0CVE-2021-1390 – Cisco IOS XE Software Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-1390
A vulnerability in one of the diagnostic test CLI commands of Cisco IOS XE Software could allow an authenticated, local attacker to execute arbitrary code on an affected device. To exploit this vulnerability, the attacker would need to have valid user credentials at privilege level 15. This vulnerability exists because the affected software permits modification of the run-time memory of an affected device under specific circumstances. An attacker could exploit this vulnerability by authenticating to the affected device and issuing a specific diagnostic test command at the CLI. A successful exploit could trigger a logic error in the code that was designed to restrict run-time memory modifications. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-XE-OFP-6Nezgn7b • CWE-123: Write-what-where Condition •
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: 7.8EPSS: 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: 5.3EPSS: 0%CPEs: 10EXPL: 0CVE-2021-1394 – Cisco IOS XE Software for Network Convergence System 520 Routers Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1394
A vulnerability in the ingress traffic manager of Cisco IOS XE Software for Cisco Network Convergence System (NCS) 520 Routers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition in the web management interface of an affected device. This vulnerability is due to incorrect processing of certain IPv4 TCP traffic that is destined to an affected device. An attacker could exploit this vulnerability by sending a large number of crafted TCP packets to the affected device. A successful exploit could allow the attacker to cause the web management interface to become unavailable, resulting in a DoS condition. Note: This vulnerability does not impact traffic that is going through the device or going to the Management Ethernet interface of the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ncs520-tcp-ZpzzOxB • CWE-399: Resource Management Errors •
CVSS: 6.9EPSS: 0%CPEs: 257EXPL: 0CVE-2021-1398 – Cisco IOS XE Software Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-1398
A vulnerability in the boot logic of Cisco IOS XE Software could allow an authenticated, local attacker with level 15 privileges or an unauthenticated attacker with physical access to execute arbitrary code on the underlying Linux operating system of an affected device. This vulnerability is due to incorrect validations of specific function arguments that are passed to the boot script. An attacker could exploit this vulnerability by tampering with a specific file, which an affected device would process during the initial boot process. On systems that are protected by the Unified Extensible Firmware Interface (UEFI) secure boot feature, a successful exploit could allow the attacker to execute unsigned code at boot time and bypass the image verification check in the secure boot process of the affected device. Una vulnerabilidad en la lógica de arranque del Software Cisco IOS XE, podría permitir a un atacante local autenticado con privilegios de nivel 15 o un atacante no autenticado con acceso físico ejecutar código arbitrario en el sistema operativo Linux subyacente de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-XE-ACE-75K3bRWe • CWE-489: Active Debug Code •
