CVSS: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-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 •
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: 8.6EPSS: 0%CPEs: 2EXPL: 0CVE-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 •
CVSS: 7.4EPSS: 0%CPEs: 2EXPL: 0CVE-2018-0475 – Cisco IOS and IOS XE Software Cluster Management Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0475
A vulnerability in the implementation of the cluster feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to trigger a denial of service (DoS) condition on an affected device. The vulnerability is due to improper input validation when handling Cluster Management Protocol (CMP) messages. An attacker could exploit this vulnerability by sending a malicious CMP message to an affected device. A successful exploit could allow the attacker to cause the switch to crash and reload or to hang, resulting in a DoS condition. If the switch hangs it will not reboot automatically, and it will need to be power cycled manually to recover. • http://www.securityfocus.com/bid/105404 http://www.securitytracker.com/id/1041737 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-cmp • CWE-20: Improper Input Validation •
CVSS: 7.1EPSS: 0%CPEs: 3EXPL: 0CVE-2018-0476 – Cisco IOS XE Software NAT Session Initiation Protocol Application Layer Gateway Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0476
A vulnerability in the Network Address Translation (NAT) Session Initiation Protocol (SIP) Application Layer Gateway (ALG) of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to improper processing of SIP packets in transit while NAT is performed on an affected device. An unauthenticated, remote attacker could exploit this vulnerability by sending crafted SIP packets via UDP port 5060 through an affected device that is performing NAT for SIP packets. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en Network Address Translation (NAT) Session Initiation Protocol (SIP) Application Layer Gateway (ALG) de Cisco IOS XE Software podría permitir que un atacante remoto no autenticado provoque el reinicio del dispositivo afectado. • http://www.securityfocus.com/bid/105419 http://www.securitytracker.com/id/1041734 http://www.securitytracker.com/id/1041737 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-sip-alg • CWE-399: Resource Management Errors •
