| CVE-2001-0537 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| HTTP server for Cisco IOS 11.3 to 12.2 allows attackers to bypass authentication and execute arbitrary commands, when local authorization is being used, by specifying a high access level in the URL. | ||||
| 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-1999-1465 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Vulnerability in Cisco IOS 11.1 through 11.3 with distributed fast switching (DFS) enabled allows remote attackers to bypass certain access control lists when the router switches traffic from a DFS-enabled input interface to an output interface with a logical subinterface, as described by Cisco bug CSCdk43862. | ||||
| CVE-2004-0710 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| IP Security VPN Services Module (VPNSM) in Cisco Catalyst 6500 Series Switch and the Cisco 7600 Series Internet Routers running IOS before 12.2(17b)SXA, before 12.2(17d)SXB, or before 12.2(14)SY03 could allow remote attackers to cause a denial of service (device crash and reload) via a malformed Internet Key Exchange (IKE) packet. | ||||
| CVE-2000-0380 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| The IOS HTTP service in Cisco routers and switches running IOS 11.1 through 12.1 allows remote attackers to cause a denial of service by requesting a URL that contains a %% string. | ||||
| CVE-2000-0700 | 1 Cisco | 4 Gigabit Switch Router 12008, Gigabit Switch Router 12012, Gigabit Switch Router 12016 and 1 more | 2026-04-16 | N/A |
| Cisco Gigabit Switch Routers (GSR) with Fast Ethernet / Gigabit Ethernet cards, from IOS versions 11.2(15)GS1A up to 11.2(19)GS0.2 and some versions of 12.0, do not properly handle line card failures, which allows remote attackers to bypass ACLs or force the interface to stop forwarding packets. | ||||
| 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-2003-0567 | 1 Cisco | 3 Ios, Ons 15454 Optical Transport Platform, Optical Networking Systems Software | 2026-04-16 | N/A |
| 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-2000-0345 | 1 Cisco | 7 Ios, Router 2500, Router 2600 and 4 more | 2026-04-16 | N/A |
| The on-line help system options in Cisco routers allows non-privileged users without "enabled" access to obtain sensitive information via the show command. | ||||
| CVE-2005-1058 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco IOS 12.2T, 12.3 and 12.3T, when processing an ISAKMP profile that specifies XAUTH authentication after Phase 1 negotiation, may not process certain attributes in the ISAKMP profile that specifies XAUTH, which allows remote attackers to bypass XAUTH and move to Phase 2 negotiations. | ||||
| CVE-2000-0368 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Classic Cisco IOS 9.1 and later allows attackers with access to the login prompt to obtain portions of the command history of previous users, which may allow the attacker to access sensitive data. | ||||
| CVE-2005-2841 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Buffer overflow in Firewall Authentication Proxy for FTP and/or Telnet Sessions for Cisco IOS 12.2ZH and 12.2ZL, 12.3 and 12.3T, and 12.4 and 12.4T allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted user authentication credentials. | ||||
| CVE-2005-2451 | 1 Cisco | 2 Ios, Ios Xr | 2026-04-16 | N/A |
| Cisco IOS 12.0 through 12.4 and IOS XR before 3.2, with IPv6 enabled, allows remote attackers on a local network segment to cause a denial of service (device reload) and possibly execute arbitrary code via a crafted IPv6 packet. | ||||
| CVE-2000-0268 | 1 Cisco | 12 3660 Router, 7100 Router, 7200 Router and 9 more | 2026-04-16 | N/A |
| Cisco IOS 11.x and 12.x allows remote attackers to cause a denial of service by sending the ENVIRON option to the Telnet daemon before it is ready to accept it, which causes the system to reboot. | ||||
| CVE-2003-0647 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Buffer overflow in the HTTP server for Cisco IOS 12.2 and earlier allows remote attackers to execute arbitrary code via an extremely long (2GB) HTTP GET request. | ||||
| CVE-2000-0984 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| The HTTP server in Cisco IOS 12.0 through 12.1 allows local users to cause a denial of service (crash and reload) via a URL containing a "?/" string. | ||||
| 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. | ||||
