CVE-2017-6736 – Cisco IOS and IOS XE Software SNMP Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2017-6736
The Simple Network Management Protocol (SNMP) subsystem of Cisco IOS 12.0 through 12.4 and 15.0 through 15.6 and IOS XE 2.2 through 3.17 contains multiple vulnerabilities that could allow an authenticated, remote attacker to remotely execute code on an affected system or cause an affected system to reload. An attacker could exploit these vulnerabilities by sending a crafted SNMP packet to an affected system via IPv4 or IPv6. Only traffic directed to an affected system can be used to exploit these vulnerabilities. The vulnerabilities are due to a buffer overflow condition in the SNMP subsystem of the affected software. The vulnerabilities affect all versions of SNMP: Versions 1, 2c, and 3. • https://www.exploit-db.com/exploits/43450 http://www.securityfocus.com/bid/99345 http://www.securitytracker.com/id/1038808 https://github.com/artkond/cisco-snmp-rce https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170629-snmp • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

CVE-2017-3857
https://notcve.org/view.php?id=CVE-2017-3857
A vulnerability in the Layer 2 Tunneling Protocol (L2TP) parsing function of Cisco IOS (12.0 through 12.4 and 15.0 through 15.6) and Cisco IOS XE (3.1 through 3.18) could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to insufficient validation of L2TP packets. An attacker could exploit this vulnerability by sending a crafted L2TP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. This vulnerability affects Cisco devices that are running a vulnerable release of Cisco IOS or Cisco IOS XE Software if the L2TP feature is enabled for the device and the device is configured as an L2TP Version 2 (L2TPv2) or L2TP Version 3 (L2TPv3) endpoint. • http://www.securityfocus.com/bid/97010 http://www.securitytracker.com/id/1038100 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170322-l2tp • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
CVE-2016-6380
https://notcve.org/view.php?id=CVE-2016-6380
The DNS forwarder in Cisco IOS 12.0 through 12.4 and 15.0 through 15.6 and IOS XE 3.1 through 3.15 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (data corruption or device reload) via a crafted DNS response, aka Bug ID CSCup90532. El redireccionador de DNS en Cisco IOS 12.0 hasta la versión 12.4 y 15.0 hasta la versión 15.6 e IOS XE 3.1 hasta la versión 3.15 permite a atacantes remotos obtener información sensible de la memoria del proceso o provocar una denegación de servicio (corrupción de datos o reinicio del dispositivo) a través de una respuesta DNS manipulada, vulnerabilidad también conocida como Bug ID CSCup90532. • http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20160928-dns http://www.securityfocus.com/bid/93201 http://www.securitytracker.com/id/1036914 https://ics-cert.us-cert.gov/advisories/ICSA-16-287-04 • CWE-20: Improper Input Validation •
