| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2017-07-17 | CVE-2017-6736 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Cisco IOS 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. | 8.8 |
| 2017-03-22 | CVE-2017-3857 | Resource Exhaustion vulnerability in Cisco IOS 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. | 7.5 |
| 2016-10-05 | CVE-2016-6393 | Resource Management Errors vulnerability in Cisco IOS XE The AAA service in Cisco IOS 12.0 through 12.4 and 15.0 through 15.6 and IOS XE 2.1 through 3.18 and 16.2 allows remote attackers to cause a denial of service (device reload) via a failed SSH connection attempt that is mishandled during generation of an error-log message, aka Bug ID CSCuy87667. | 7.5 |
| 2016-10-05 | CVE-2016-6380 | Improper Input Validation vulnerability in Cisco products 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. | 8.1 |
| 2016-09-22 | CVE-2014-2146 | Improper Input Validation vulnerability in Cisco IOS XE 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. | 6.5 |
| 2016-09-18 | CVE-2016-6403 | Resource Management Errors vulnerability in Cisco IOS The Data in Motion (DMo) application in Cisco IOS 15.6(1)T and IOS XE, when the IOx feature set is enabled, allows remote attackers to cause a denial of service via a crafted packet, aka Bug IDs CSCuy82904, CSCuy82909, and CSCuy82912. | 5.9 |
| 2016-05-29 | CVE-2016-1409 | Improper Input Validation vulnerability in Cisco products The Neighbor Discovery (ND) protocol implementation in the IPv6 stack in Cisco IOS XE 2.1 through 3.17S, IOS XR 2.0.0 through 5.3.2, and NX-OS allows remote attackers to cause a denial of service (packet-processing outage) via crafted ND messages, aka Bug ID CSCuz66542, as exploited in the wild in May 2016. | 7.5 |
| 2004-12-31 | CVE-2004-1464 | Unspecified vulnerability in Cisco IOS Cisco IOS 12.2(15) and earlier allows remote attackers to cause a denial of service (refused VTY (virtual terminal) connections), via a crafted TCP connection to the Telnet or reverse Telnet port. | 5.9 |
| 2002-12-31 | CVE-2002-1706 | Improper Verification of Cryptographic Signature vulnerability in Cisco IOS Cisco IOS software 11.3 through 12.2 running on Cisco uBR7200 and uBR7100 series Universal Broadband Routers allows remote attackers to modify Data Over Cable Service Interface Specification (DOCSIS) settings via a DOCSIS file without a Message Integrity Check (MIC) signature, which is approved by the router. | 7.5 |
