CVSS: 7.2EPSS: 0%CPEs: 3EXPL: 0CVE-2018-0481 – Cisco IOS XE Software Command Injection Vulnerabilities
https://notcve.org/view.php?id=CVE-2018-0481
A vulnerability in the CLI parser of Cisco IOS XE Software could allow an authenticated, local attacker to execute commands on the underlying Linux shell of an affected device with root privileges. The vulnerability exist because the affected software improperly sanitizes command arguments, failing to prevent access to certain internal data structures on an affected device. An attacker who has privileged EXEC mode (privilege level 15) access to an affected device could exploit these vulnerabilities on the device by executing CLI commands that contain custom arguments. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the affected device. Una vulnerabilidad en el analizador CLI de Cisco IOS XE Software podría permitir que un atacante local autenticado ejecute comandos en el shell Linux subyacente de un dispositivo afectado con privilegios root. • http://www.securitytracker.com/id/1041737 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-iosxe-cmdinj • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 8.6EPSS: 0%CPEs: 3EXPL: 0CVE-2018-0467 – Cisco IOS and IOS XE Software IPv6 Hop-by-Hop Options Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0467
A vulnerability in the IPv6 processing code of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to cause the device to reload. The vulnerability is due to incorrect handling of specific IPv6 hop-by-hop options. An attacker could exploit this vulnerability by sending a malicious IPv6 packet to or through the affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition on an affected device. Una vulnerabilidad en el código de procesamiento IPv6 en Cisco IOS y Cisco IOS XE Software podría permitir que un atacante remoto sin autenticar haga que el dispositivo se reinicie. • http://www.securitytracker.com/id/1041737 https://ics-cert.us-cert.gov/advisories/ICSA-19-094-03 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-ipv6hbh • CWE-20: Improper Input Validation •
CVSS: 7.4EPSS: 0%CPEs: 2EXPL: 0CVE-2018-0471 – Cisco IOS XE Software Cisco Discovery Protocol Memory Leak Vulnerability
https://notcve.org/view.php?id=CVE-2018-0471
A vulnerability in the Cisco Discovery Protocol (CDP) module of Cisco IOS XE Software Releases 16.6.1 and 16.6.2 could allow an unauthenticated, adjacent attacker to cause a memory leak that may lead to a denial of service (DoS) condition. The vulnerability is due to incorrect processing of certain CDP packets. An attacker could exploit this vulnerability by sending certain CDP packets to an affected device. A successful exploit could cause an affected device to continuously consume memory and eventually result in a memory allocation failure that leads to a crash, triggering a reload of the affected device. Una vulnerabilidad en el módulo Cisco Discovery Protocol (CDP) de Cisco IOS XE en versiones de software 16.6.1 y 16.6.2 podría permitir que un atacante adyacente sin autenticar provoque una fuga de memoria que podría conducir a una denegación de servicio (DoS). • http://www.securityfocus.com/bid/105398 http://www.securitytracker.com/id/1041737 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-cdp-memleak • CWE-400: Uncontrolled Resource Consumption CWE-772: Missing Release of Resource after Effective Lifetime •

CVSS: 7.2EPSS: 0%CPEs: 1EXPL: 0CVE-2018-15374 – Cisco IOS XE Software Digital Signature Verification Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2018-15374
A vulnerability in the Image Verification feature of Cisco IOS XE Software could allow an authenticated, local attacker to install a malicious software image or file on an affected device. The vulnerability is due to the affected software improperly verifying digital signatures for software images and files that are uploaded to a device. An attacker could exploit this vulnerability by uploading a malicious software image or file to an affected device. A successful exploit could allow the attacker to bypass digital signature verification checks for software images and files and install a malicious software image or file on the affected device.
