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-2017-6770
https://notcve.org/view.php?id=CVE-2017-6770
Cisco IOS 12.0 through 15.6, Adaptive Security Appliance (ASA) Software 7.0.1 through 9.7.1.2, NX-OS 4.0 through 12.0, and IOS XE 3.6 through 3.18 are affected by a vulnerability involving the Open Shortest Path First (OSPF) Routing Protocol Link State Advertisement (LSA) database. This vulnerability could allow an unauthenticated, remote attacker to take full control of the OSPF Autonomous System (AS) domain routing table, allowing the attacker to intercept or black-hole traffic. The attacker could exploit this vulnerability by injecting crafted OSPF packets. Successful exploitation could cause the targeted router to flush its routing table and propagate the crafted OSPF LSA type 1 update throughout the OSPF AS domain. To exploit this vulnerability, an attacker must accurately determine certain parameters within the LSA database on the target router. • http://www.securityfocus.com/bid/100005 http://www.securitytracker.com/id/1039005 http://www.securitytracker.com/id/1039006 http://www.securitytracker.com/id/1039007 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170727-ospf • CWE-20: Improper Input Validation •
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 •
