| Cisco IOS 12.0 through 12.3YL, with BGP enabled and running the bgp log-neighbor-changes command, allows remote attackers to cause a denial of service (device reload) via a malformed BGP packet. | ||||
| CVE-2005-4826 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Unspecified vulnerability in the VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(22)EA3 on Catalyst 2950T switches allows remote attackers to cause a denial of service (device reboot) via a crafted Subset-Advert message packet, a different issue than CVE-2006-4774, CVE-2006-4775, and CVE-2006-4776. | ||||
| CVE-2001-0711 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco IOS 11.x and 12.0 with ATM support allows attackers to cause a denial of service via the undocumented Interim Local Management Interface (ILMI) SNMP community string. | ||||
| CVE-2004-1775 | 1 Cisco | 2 Catos, Ios | 2026-04-16 | N/A |
| Cisco VACM (View-based Access Control MIB) for Catalyst Operating Software (CatOS) 5.5 and 6.1 and IOS 12.0 and 12.1 allows remote attackers to read and modify device configuration via the read-write community string. | ||||
| CVE-2004-1776 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco IOS 12.1(3) and 12.1(3)T allows remote attackers to read and modify device configuration data via the cable-docsis read-write community string used by the Data Over Cable Service Interface Specification (DOCSIS) standard. | ||||
| CVE-2005-2105 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco IOS 12.2T through 12.4 allows remote attackers to bypass Authentication, Authorization, and Accounting (AAA) RADIUS authentication, if the fallback method is set to none, via a long username. | ||||
| CVE-2002-2315 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco IOS 11.2.x and 12.0.x does not limit the size of its redirect table, which allows remote attackers to cause a denial of service (memory consumption) via spoofed ICMP redirect packets to the router. | ||||
| CVE-2004-1111 | 1 Cisco | 10 7200 Router, 7300 Router, 7500 Router and 7 more | 2026-04-16 | N/A |
| Cisco IOS 2.2(18)EW, 12.2(18)EWA, 12.2(14)SZ, 12.2(18)S, 12.2(18)SE, 12.2(18)SV, 12.2(18)SW, and other versions without the "no service dhcp" command, keep undeliverable DHCP packets in the queue instead of dropping them, which allows remote attackers to cause a denial of service (dropped traffic) via multiple undeliverable DHCP packets that exceed the input queue size. | ||||
| CVE-2003-0512 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco IOS 12.2 and earlier generates a "% Login invalid" message instead of prompting for a password when an invalid username is provided, which allows remote attackers to identify valid usernames on the system and conduct brute force password guessing, as reported for the Aironet Bridge. | ||||
| CVE-1999-0159 | 1 Cisco | 1 Ios | 2026-04-16 | 3.5 Low |
| Attackers can crash a Cisco IOS router or device, provided they can get to an interactive prompt (such as a login). This applies to some IOS 9.x, 10.x, and 11.x releases. | ||||
| CVE-2003-1109 | 1 Cisco | 4 Ios, Ip Phone 7940, Ip Phone 7960 and 1 more | 2026-04-16 | N/A |
| The Session Initiation Protocol (SIP) implementation in multiple Cisco products including IP Phone models 7940 and 7960, IOS versions in the 12.2 train, and Secure PIX 5.2.9 to 6.2.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted INVITE messages, as demonstrated by the OUSPG PROTOS c07-sip test suite. | ||||
| CVE-2001-1071 | 1 Cisco | 2 Catos, Ios | 2026-04-16 | N/A |

| PPTP implementation in Cisco IOS 12.1 and 12.2 allows remote attackers to cause a denial of service (crash) via a malformed packet. | ||||

| 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. | ||||
| CVE-2002-2208 | 2 Cisco, Extended Interior Gateway Routing Protocol | 2 Ios, Extended Interior Gateway Routing Protocol | 2026-04-16 | N/A |
| 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. | ||||
