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 •
CVE-2017-3850
https://notcve.org/view.php?id=CVE-2017-3850
A vulnerability in the Autonomic Networking Infrastructure (ANI) feature of Cisco IOS Software (15.4 through 15.6) and Cisco IOS XE Software (3.7 through 3.18, and 16) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to incomplete input validation on certain crafted packets. An attacker could exploit this vulnerability by sending a crafted IPv6 packet to a device that is running a Cisco IOS Software or Cisco IOS XE Software release that supports the ANI feature. A device must meet two conditions to be affected by this vulnerability: (1) the device must be running a version of Cisco IOS Software or Cisco IOS XE Software that supports ANI (regardless of whether ANI is configured); and (2) the device must have a reachable IPv6 interface. An exploit could allow the attacker to cause the affected device to reload. • http://www.securityfocus.com/bid/96971 http://www.securitytracker.com/id/1038065 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170320-aniipv6 • CWE-20: Improper Input Validation •
CVE-2017-3849
https://notcve.org/view.php?id=CVE-2017-3849
A vulnerability in the Autonomic Networking Infrastructure (ANI) registrar feature of Cisco IOS Software (possibly 15.2 through 15.6) and Cisco IOS XE Software (possibly 3.7 through 3.18, and 16) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. The vulnerability is due to incomplete input validation on certain crafted packets. An attacker could exploit this vulnerability by sending a crafted autonomic network channel discovery packet to a device that has all the following characteristics: (1) running a Cisco IOS Software or Cisco IOS XE Software release that supports the ANI feature; (2) configured as an autonomic registrar; (3) has a whitelist configured. An exploit could allow the attacker to cause the affected device to reload. Note: Autonomic networking should be configured with a whitelist. • http://www.securityfocus.com/bid/96972 http://www.securitytracker.com/id/1038064 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170320-ani • CWE-20: Improper Input Validation •
CVE-2016-6379
https://notcve.org/view.php?id=CVE-2016-6379
Cisco IOS 12.2 and IOS XE 3.14 through 3.16 and 16.1 allow remote attackers to cause a denial of service (device reload) via crafted IP Detail Record (IPDR) packets, aka Bug ID CSCuu35089. Cisco IOS 12.2 e IOS XE 3.14 hasta la versión 3.16 y 16.1 permiten a atacantes remotos provocar una denegación de servicio (recarga del dispositivo) a través de paquetes IP Detail Record (IPDR) manipulados, vulnerabilidad también conocida como Bug ID CSCuu35089. • http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20160928-ipdr http://www.securityfocus.com/bid/93205 http://www.securitytracker.com/id/1036914 • CWE-20: Improper Input Validation •
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 •
