A vulnerability in the REST API of the web-based user interface (web UI) of Cisco IOS XE 3.1 through 16.5 could allow an unauthenticated, remote attacker to bypass authentication to the REST API of the web UI of the affected software. The vulnerability is due to insufficient input validation for the REST API of the affected software. An attacker could exploit this vulnerability by sending a malicious API request to an affected device. A successful exploit could allow the attacker to bypass authentication and gain access to the web UI of the affected software. This vulnerability affects Cisco devices that are running a vulnerable release of Cisco IOS XE Software, if the HTTP Server feature is enabled for the device. • http://www.securityfocus.com/bid/101032 http://www.securitytracker.com/id/1039447 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170927-restapi • CWE-287: Improper Authentication •

https://notcve.org/view.php?id=CVE-2017-12236
A vulnerability in the implementation of the Locator/ID Separation Protocol (LISP) in Cisco IOS XE 3.2 through 16.5 could allow an unauthenticated, remote attacker using an x tunnel router to bypass authentication checks performed when registering an Endpoint Identifier (EID) to a Routing Locator (RLOC) in the map server/map resolver (MS/MR). The vulnerability is due to a logic error introduced via a code regression for the affected software. An attacker could exploit this vulnerability by sending specific valid map-registration requests, which will be accepted by the MS/MR even if the authentication keys do not match, to the affected software. A successful exploit could allow the attacker to inject invalid mappings of EIDs to RLOCs in the MS/MR of the affected software. This vulnerability affects Cisco devices that are configured with LISP acting as an IPv4 or IPv6 map server. • http://www.securityfocus.com/bid/101033 http://www.securitytracker.com/id/1039448 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170927-lisp • CWE-287: Improper Authentication •
CVSS: 7.8EPSS: 0%CPEs: 491EXPL: 0CVE-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 •

https://notcve.org/view.php?id=CVE-2017-6770
Cisco IOS 12.0 through 15.6, Adaptive Security Appliance (ASA) Software 7.0.1 through 9.7.1.2, NX-OS 4.0 through 12.0, and IOS XE 3.6 through 3.18 are affected by a vulnerability involving the Open Shortest Path First (OSPF) Routing Protocol Link State Advertisement (LSA) database. This vulnerability could allow an unauthenticated, remote attacker to take full control of the OSPF Autonomous System (AS) domain routing table, allowing the attacker to intercept or black-hole traffic. The attacker could exploit this vulnerability by injecting crafted OSPF packets. Successful exploitation could cause the targeted router to flush its routing table and propagate the crafted OSPF LSA type 1 update throughout the OSPF AS domain. To exploit this vulnerability, an attacker must accurately determine certain parameters within the LSA database on the target router. • http://www.securityfocus.com/bid/100005 http://www.securitytracker.com/id/1039005 http://www.securitytracker.com/id/1039006 http://www.securitytracker.com/id/1039007 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170727-ospf • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2017-6741
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. • http://www.securityfocus.com/bid/99345 http://www.securitytracker.com/id/1038808 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 •
