CVSS: 7.2EPSS: 0%CPEs: 3EXPL: 0CVE-2019-12666 – Cisco IOS XE Software Path Traversal Vulnerability
https://notcve.org/view.php?id=CVE-2019-12666
A vulnerability in the Guest Shell of Cisco IOS XE Software could allow an authenticated, local attacker to perform directory traversal on the base Linux operating system of Cisco IOS XE Software. The vulnerability is due to incomplete validation of certain commands. An attacker could exploit this vulnerability by first accessing the Guest Shell and then entering specific commands. A successful exploit could allow the attacker to execute arbitrary code on the base Linux operating system. Una vulnerabilidad en el Guest Shell del Software Cisco IOS XE, podría permitir a un atacante local autenticado realizar un salto de directorio en el sistema operativo base Linux del software Cisco IOS XE. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-dt • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2019-12664 – Cisco IOS XE Software ISDN Data Leak Vulnerability
https://notcve.org/view.php?id=CVE-2019-12664
A vulnerability in the Dialer interface feature for ISDN connections in Cisco IOS XE Software for Cisco 4000 Series Integrated Services Routers (ISRs) could allow an unauthenticated, adjacent attacker to pass IPv4 traffic through an ISDN channel prior to successful PPP authentication. The vulnerability is due to insufficient validation of the state of the PPP IP Control Protocol (IPCP). An attacker could exploit this vulnerability by making an ISDN call to an affected device and sending traffic through the ISDN channel prior to successful PPP authentication. Alternatively, an unauthenticated, remote attacker could exploit this vulnerability by sending traffic through an affected device that is configured to exit via an ISDN connection for which both the Dialer interface and the Basic Rate Interface (BRI) have been configured, but the Challenge Handshake Authentication Protocol (CHAP) password for PPP does not match the remote end. A successful exploit could allow the attacker to pass IPv4 traffic through an unauthenticated ISDN connection for a few seconds, from initial ISDN call setup until PPP authentication fails. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-isdn-data-leak • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-287: Improper Authentication •
CVSS: 7.2EPSS: 0%CPEs: 138EXPL: 0CVE-2019-12662 – Cisco NX-OS and IOS XE Software Virtual Service Image Signature Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-12662
A vulnerability in Cisco NX-OS Software and Cisco IOS XE Software could allow an authenticated, local attacker with valid administrator or privilege level 15 credentials to load a virtual service image and bypass signature verification on an affected device. The vulnerability is due to improper signature verification during the installation of an Open Virtual Appliance (OVA) image. An authenticated, local attacker could exploit this vulnerability and load a malicious, unsigned OVA image on an affected device. A successful exploit could allow an attacker to perform code execution on a crafted software OVA image. Una vulnerabilidad en el Software Cisco NX-OS y el Software Cisco IOS XE, podría permitir que un atacante local autenticado con credenciales válidas de administrador o nivel de privilegio 15 cargue una imagen de servicio virtual y omita la comprobación de firma en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-vman • CWE-347: Improper Verification of Cryptographic Signature •

https://notcve.org/view.php?id=CVE-2019-12660
A vulnerability in the CLI of Cisco IOS XE Software could allow an authenticated, local attacker to write values to the underlying memory of an affected device. The vulnerability is due to improper input validation and authorization of specific commands that a user can execute within the CLI. An attacker could exploit this vulnerability by authenticating to an affected device and issuing a specific set of commands. A successful exploit could allow the attacker to modify the configuration of the device to cause it to be non-secure and abnormally functioning. Una vulnerabilidad en la CLI del Software Cisco IOS XE, podría permitir a un atacante local autenticado escribir valores en la memoria subyacente de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-awr • CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 8.6EPSS: 0%CPEs: 152EXPL: 0CVE-2019-12658 – Cisco IOS XE Software Filesystem Exhaustion Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12658
A vulnerability in the filesystem resource management code of Cisco IOS XE Software could allow an unauthenticated, remote attacker to exhaust filesystem resources on an affected device and cause a denial of service (DoS) condition. The vulnerability is due to ineffective management of the underlying filesystem resources. An attacker could exploit this vulnerability by performing specific actions that result in messages being sent to specific operating system log files. A successful exploit could allow the attacker to exhaust available filesystem space on an affected device. This could cause the device to crash and reload, resulting in a DoS condition for clients whose network traffic is transiting the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-iosxe-fsdos • CWE-400: Uncontrolled Resource Consumption •
