| Memory leak in Secure Shell (SSH) in Cisco IOS 12.0 through 12.3, when authenticating against a TACACS+ server, allows remote attackers to cause a denial of service (memory consumption) via an incorrect username or password. | ||||
| CVE-2001-0750 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco IOS 12.1(2)T, 12.1(3)T allow remote attackers to cause a denial of service (reload) via a connection to TCP ports 3100-3999, 5100-5999, 7100-7999 and 10100-10999. | ||||
| CVE-1999-0160 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Some classic Cisco IOS devices have a vulnerability in the PPP CHAP authentication to establish unauthorized PPP connections. | ||||
| CVE-2002-1359 | 7 Cisco, Fissh, Intersoft and 4 more | 7 Ios, Ssh Client, Securenetterm and 4 more | 2026-04-16 | N/A |
| Multiple SSH2 servers and clients do not properly handle large packets or large fields, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code via buffer overflow attacks, as demonstrated by the SSHredder SSH protocol test suite. | ||||
| CVE-2002-2053 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| 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. | ||||
| 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-2003-0511 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| The web server for Cisco Aironet AP1x00 Series Wireless devices running certain versions of IOS 12.2 allow remote attackers to cause a denial of service (reload) via a malformed URL. | ||||
| CVE-2001-0288 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| 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. | ||||
| CVE-2005-4258 | 1 Cisco | 71 Catalyst, Catalyst 1200 Series, Catalyst 1900 Series and 68 more | 2026-04-16 | N/A |
| Unspecified Cisco Catalyst Switches allow remote attackers to cause a denial of service (device crash) via an IP packet with the same source and destination IPs and ports, and with the SYN flag set (aka LanD). NOTE: the provenance of this issue is unknown; the details are obtained solely from the BID. | ||||
| CVE-2005-0186 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco IOS 12.1YD, 12.2T, 12.3 and 12.3T, when configured for the IOS Telephony Service (ITS), CallManager Express (CME) or Survivable Remote Site Telephony (SRST), allows remote attackers to cause a denial of service (device reboot) via a malformed packet to the SCCP port. | ||||
| 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-2001-1183 | 1 Cisco | 1 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. | ||||
| CVE-1999-0775 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco Gigabit Switch routers running IOS allow remote attackers to forward unauthorized packets due to improper handling of the "established" keyword in an access list. | ||||
| CVE-2005-3669 | 1 Cisco | 8 Adaptive Security Appliance Software, Firewall Services Module, Ios and 5 more | 2026-04-16 | N/A |
| Multiple unspecified vulnerabilities in the Internet Key Exchange version 1 (IKEv1) implementation in multiple Cisco products allow remote attackers to cause a denial of service (device reset) via certain malformed IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the Cisco advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to. | ||||
| CVE-2005-3921 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cross-site scripting (XSS) vulnerability in Cisco IOS Web Server for IOS 12.0(2a) allows remote attackers to inject arbitrary web script or HTML by (1) packets containing HTML that an administrator views via an HTTP interface to the contents of memory buffers, as demonstrated by the URI /level/15/exec/-/buffers/assigned/dump; or (2) sending the router Cisco Discovery Protocol (CDP) packets with HTML payload that an administrator views via the CDP status pages. NOTE: these vectors were originally reported as being associated with the dump and packet options in /level/15/exec/-/show/buffers. | ||||
