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-2017-3856
https://notcve.org/view.php?id=CVE-2017-3856
A vulnerability in the web user interface of Cisco IOS XE 3.1 through 3.17 could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to insufficient resource handling by the affected software when the web user interface is under a high load. An attacker could exploit this vulnerability by sending a high number of requests to the web user interface of the affected software. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. To exploit this vulnerability, the attacker must have access to the management interface of the affected software, which is typically connected to a restricted management network. • http://www.securityfocus.com/bid/97007 http://www.securitytracker.com/id/1038101 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170322-webui • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
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-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 •
