CVE-2017-6627 – Cisco IOS Software and Cisco IOS XE Software UDP Packet Processing Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2017-6627
A vulnerability in the UDP processing code of Cisco IOS 15.1, 15.2, and 15.4 and IOS XE 3.14 through 3.18 could allow an unauthenticated, remote attacker to cause the input queue of an affected system to hold UDP packets, causing an interface queue wedge and a denial of service (DoS) condition. The vulnerability is due to Cisco IOS Software application changes that create UDP sockets and leave the sockets idle without closing them. An attacker could exploit this vulnerability by sending UDP packets with a destination port of 0 to an affected device. A successful exploit could allow the attacker to cause UDP packets to be held in the input interfaces queue, resulting in a DoS condition. The input interface queue will stop holding UDP packets when it receives 250 packets. • http://www.securityfocus.com/bid/100644 http://www.securitytracker.com/id/1039289 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170906-ios-udp • CWE-399: Resource Management Errors CWE-404: Improper Resource Shutdown or Release •
CVE-2017-6663 – Cisco IOS Software and Cisco IOS XE Software Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2017-6663
A vulnerability in the Autonomic Networking feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause autonomic nodes of an affected system to reload, resulting in a denial of service (DoS) condition. More Information: CSCvd88936. Known Affected Releases: Denali-16.2.1 Denali-16.3.1. Una vulnerabilidad en la característica Autonomic Networking de Cisco IOS Software y Cisco IOS XE Software podría permitir que un atacante no autenticado y en redes adyacentes provoque que los nodos autonómicos de un sistema afectado se vuelvan a cargar, lo que resultaría en una condición de denegación de servicio (DoS).

CVE-2017-6665
https://notcve.org/view.php?id=CVE-2017-6665
A vulnerability in the Autonomic Networking feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to reset the Autonomic Control Plane (ACP) of an affected system and view ACP packets that are transferred in clear text within an affected system, an Information Disclosure Vulnerability. More Information: CSCvd51214. Known Affected Releases: Denali-16.2.1 Denali-16.3.1. Una vulnerabilidad en la funcionalidad Autonomic Networking de Cisco IOS Software y Cisco IOS XE Software podría permitir que un atacante adyacente sin autenticar reinicie el Autonomic Control Plane (ACP) de un sistema afectado y vea los paquetes ACP que se transfieren sin cifrar dentro de un sistema afectado (vulnerabilidad de divulgación de información).

CVE-2012-5030
https://notcve.org/view.php?id=CVE-2012-5030
Cisco IOS before 15.2(4)S6 does not initialize an unspecified variable, which might allow remote authenticated users to cause a denial of service (CPU consumption, watchdog timeout, crash) by walking specific SNMP objects. Cisco IOS en versiones anteriores a 15.2(4)S6 no inicializa una variable no especificada, lo que podría permitir que usuarios remotos autenticados provoquen una denegación de servicio (consumo de CPU, watchdog timeout, caída del sistema) recorriendo objetos SNMP específicos. • https://www.cisco.com/c/en/us/td/docs/ios/15_2s/release/notes/15_2s_rel_notes/15_2s_caveats_15_2_4s.html • CWE-399: Resource Management Errors •
CVE-2017-3859
https://notcve.org/view.php?id=CVE-2017-3859
A vulnerability in the DHCP code for the Zero Touch Provisioning feature of Cisco ASR 920 Series Aggregation Services Routers could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to a format string vulnerability when processing a crafted DHCP packet for Zero Touch Provisioning. An attacker could exploit this vulnerability by sending a specially crafted DHCP packet to an affected device. An exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition. This vulnerability affects Cisco ASR 920 Series Aggregation Services Routers that are running an affected release of Cisco IOS XE Software (3.13 through 3.18) and are listening on the DHCP server port. • http://www.securityfocus.com/bid/97008 http://www.securitytracker.com/id/1038104 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170322-ztp • CWE-134: Use of Externally-Controlled Format String •
