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 •
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 •
