| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2003-08-18 | CVE-2003-0567 | Improper Input Validation vulnerability in Cisco products Cisco IOS 11.x and 12.0 through 12.2 allows remote attackers to cause a denial of service (traffic block) by sending a particular sequence of IPv4 packets to an interface on the device, causing the input queue on that interface to be marked as full. | 7.8 |
| 2002-12-31 | CVE-2002-2208 | Denial Of Service vulnerability in Cisco IOS EIGRP Announcement ARP Extended Interior Gateway Routing Protocol (EIGRP), as implemented in Cisco IOS 11.3 through 12.2 and other products, allows remote attackers to cause a denial of service (flood) by sending a large number of spoofed EIGRP neighbor announcements, which results in an ARP storm on the local network. | 7.8 |
| 2002-12-31 | CVE-2002-2053 | Denial Of Service vulnerability in Cisco IOS 12.1 The design of the Hot Standby Routing Protocol (HSRP), as implemented on Cisco IOS 12.1, when using IRPAS, allows remote attackers to cause a denial of service (CPU consumption) via a router with the same IP address as the interface on which HSRP is running, which causes a loop. | 5.0 |
| 2002-12-31 | CVE-2002-1768 | Denial of Service vulnerability in Cisco Malformed HSRP Traffic Cisco IOS 11.1 through 12.2, when HSRP support is not enabled, allows remote attackers to cause a denial of service (CPU consumption) via randomly sized UDP packets to the Hot Standby Routing Protocol (HSRP) port 1985. | 5.0 |
| 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 |
| 2002-06-25 | CVE-2002-0339 | Unspecified vulnerability in Cisco IOS Cisco IOS 11.1CC through 12.2 with Cisco Express Forwarding (CEF) enabled includes portions of previous packets in the padding of a MAC level packet when the MAC packet's length is less than the IP level packet length. | 5.0 |
| 2001-11-28 | CVE-2001-0929 | Unspecified vulnerability in Cisco IOS Cisco IOS Firewall Feature set, aka Context Based Access Control (CBAC) or Cisco Secure Integrated Software, for IOS 11.2P through 12.2T does not properly check the IP protocol type, which could allow remote attackers to bypass access control lists. | 7.5 |
| 2001-10-09 | CVE-2001-1071 | Denial of Service vulnerability in Cisco Catos and IOS Cisco IOS 12.2 and earlier running Cisco Discovery Protocol (CDP) allows remote attackers to cause a denial of service (memory consumption) via a flood of CDP neighbor announcements. | 5.0 |
| 2001-07-24 | CVE-2001-1097 | Denial of Service vulnerability in Cisco IOS UDP Cisco routers and switches running IOS 12.0 through 12.2.1 allows a remote attacker to cause a denial of service via a flood of UDP packets. | 5.0 |
| 2001-05-03 | CVE-2001-0288 | Unspecified vulnerability in Cisco IOS Cisco switches and routers running IOS 12.1 and earlier produce predictable TCP Initial Sequence Numbers (ISNs), which allows remote attackers to spoof or hijack TCP connections. | 7.5 |
