CVE-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 •
CVE-2018-0469 – Cisco IOS XE Software Web UI Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0469
A vulnerability in the web user interface of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to a double-free-in-memory handling by the affected software when specific HTTP requests are processed. An attacker could exploit this vulnerability by sending specific HTTP requests to the web user interface of the affected software. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition on an affected device. To exploit this vulnerability, the attacker must have access to the management interface of the affected software, which is typically connected to a restricted management network. • http://www.securityfocus.com/bid/105423 http://www.securitytracker.com/id/1041737 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-webuidos • CWE-415: Double Free •
CVE-2018-0470 – Cisco IOS XE Software HTTP Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0470
A vulnerability in the web framework of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a buffer overflow condition on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to the affected software improperly parsing malformed HTTP packets that are destined to a device. An attacker could exploit this vulnerability by sending a malformed HTTP packet to an affected device for processing. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected device, resulting in a DoS condition. Una vulnerabilidad en el framework web de Cisco IOS XE Software podría permitir que un atacante remoto sin autenticar provoque un desbordamiento de búfer en un dispositivo afectado, lo que resulta en una denegación de servicio (DoS). • http://www.securityfocus.com/bid/105397 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-webdos • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-399: Resource Management Errors •
CVE-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 •
CVE-2018-0472 – Cisco IOS XE Software and Cisco ASA 5500-X Series Adaptive Security Appliance IPsec Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0472
A vulnerability in the IPsec driver code of multiple Cisco IOS XE Software platforms and the Cisco ASA 5500-X Series Adaptive Security Appliance (ASA) could allow an unauthenticated, remote attacker to cause the device to reload. The vulnerability is due to improper processing of malformed IPsec Authentication Header (AH) or Encapsulating Security Payload (ESP) packets. An attacker could exploit this vulnerability by sending malformed IPsec packets to be processed by an affected device. An exploit could allow the attacker to cause a reload of the affected device. Una vulnerabilidad en el código del controlador IPsec de múltiples plataformas Cisco IOS XE Software y Cisco ASA 5500-X Series Adaptive Security Appliance (ASA) podría permitir que un atacante remoto no autenticado provoque la recarga del dispositivo. • http://www.securityfocus.com/bid/105418 http://www.securitytracker.com/id/1041735 http://www.securitytracker.com/id/1041737 https://ics-cert.us-cert.gov/advisories/ICSA-19-094-04 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-ipsec • CWE-20: Improper Input Validation •
