CVE-2017-12237 – Cisco IOS and IOS XE Software Internet Key Exchange Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2017-12237
A vulnerability in the Internet Key Exchange Version 2 (IKEv2) module of Cisco IOS 15.0 through 15.6 and Cisco IOS XE 3.5 through 16.5 could allow an unauthenticated, remote attacker to cause high CPU utilization, traceback messages, or a reload of an affected device that leads to a denial of service (DoS) condition. The vulnerability is due to how an affected device processes certain IKEv2 packets. An attacker could exploit this vulnerability by sending specific IKEv2 packets to an affected device to be processed. A successful exploit could allow the attacker to cause high CPU utilization, traceback messages, or a reload of the affected device that leads to a DoS condition. This vulnerability affects Cisco devices that have the Internet Security Association and Key Management Protocol (ISAKMP) enabled. • http://www.securityfocus.com/bid/101037 http://www.securitytracker.com/id/1039460 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170927-ike • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
CVE-2010-3050
https://notcve.org/view.php?id=CVE-2010-3050
Cisco IOS before 12.2(33)SXI allows remote authenticated users to cause a denial of service (device reboot). Cisco IOS en versiones anteriores a la 12.2(33)SXI permite que los usuarios autenticados remotos provoquen una denegación de servicio (reinicio del dispositivo). • https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/12-2SX/release/notes/ol_14271/caveats_SXI_rebuilds.html • CWE-20: Improper Input Validation •
CVE-2010-3049
https://notcve.org/view.php?id=CVE-2010-3049
Cisco IOS before 12.2(33)SXI allows local users to cause a denial of service (device reboot). Cisco IOS en versiones anteriores a la 12.2(33)SXI permite que los usuarios locales provoquen una denegación de servicio (reinicio del dispositivo). • https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/12-2SX/release/notes/ol_14271/caveats_SXI_rebuilds.html • 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 •
CVE-2014-2146
https://notcve.org/view.php?id=CVE-2014-2146
The Zone-Based Firewall (ZBFW) functionality in Cisco IOS, possibly 15.4 and earlier, and IOS XE, possibly 3.13 and earlier, mishandles zone checking for existing sessions, which allows remote attackers to bypass intended resource-access restrictions via spoofed traffic that matches one of these sessions, aka Bug IDs CSCun94946 and CSCun96847. La funcionalidad Zone-Based Firewall (ZBFW) en Cisco IOS, posiblemente 15.4 y versiones anteriores e IOS XE, posiblemente 3.13 y versiones anteriores, no maneja adecuadamente la zona de comprobación de las sesiones existentes, lo que permite a atacantes remotos eludir las restricciones de acceso a los recursos intencionadas a través de tráfico suplantado que coincide con una de estas sesiones, vulnerabilidad también conocida como Bug IDs CSCun94946 y CSCun96847. • http://www.securityfocus.com/bid/93126 https://tools.cisco.com/security/center/viewAlert.x?alertId=39129 • CWE-20: Improper Input Validation •
