CVE-2017-12236
https://notcve.org/view.php?id=CVE-2017-12236
A vulnerability in the implementation of the Locator/ID Separation Protocol (LISP) in Cisco IOS XE 3.2 through 16.5 could allow an unauthenticated, remote attacker using an x tunnel router to bypass authentication checks performed when registering an Endpoint Identifier (EID) to a Routing Locator (RLOC) in the map server/map resolver (MS/MR). The vulnerability is due to a logic error introduced via a code regression for the affected software. An attacker could exploit this vulnerability by sending specific valid map-registration requests, which will be accepted by the MS/MR even if the authentication keys do not match, to the affected software. A successful exploit could allow the attacker to inject invalid mappings of EIDs to RLOCs in the MS/MR of the affected software. This vulnerability affects Cisco devices that are configured with LISP acting as an IPv4 or IPv6 map server. • http://www.securityfocus.com/bid/101033 http://www.securitytracker.com/id/1039448 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170927-lisp • CWE-287: Improper Authentication •
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-2017-12211
https://notcve.org/view.php?id=CVE-2017-12211
A vulnerability in the IPv6 Simple Network Management Protocol (SNMP) code of Cisco IOS and Cisco IOS XE Software could allow an authenticated, remote attacker to cause high CPU usage or a reload of the device. The vulnerability is due to IPv6 sub block corruption. An attacker could exploit this vulnerability by polling the affected device IPv6 information. An exploit could allow the attacker to trigger high CPU usage or a reload of the device. Known Affected Releases: Denali-16.3.1. • http://www.securityfocus.com/bid/100648 http://www.securitytracker.com/id/1039290 https://quickview.cloudapps.cisco.com/quickview/bug/CSCvb14640 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170906-snmp • CWE-399: Resource Management Errors •
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).
