Cisco IOS 12.0S, 12.2, and 12.3, with Open Shortest Path First (OSPF) enabled, allows remote attackers to cause a denial of service (device reload) via a malformed OSPF 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-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-1999-0293 1 Cisco 1 Ios 2026-04-16 N/A
AAA authentication on Cisco systems allows attackers to execute commands without authorization.
CVE-1999-1306 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 9.1 and earlier does not properly handle extended IP access lists when the IP route cache is enabled and the "established" keyword is set, which could allow attackers to bypass filters.
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-2001-1097 1 Cisco 1 Ios 2026-04-16 N/A
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.
CVE-2005-1020 1 Cisco 1 Ios 2026-04-16 N/A
Secure Shell (SSH) 2 in Cisco IOS 12.0 through 12.3 allows remote attackers to cause a denial of service (device reload) (1) via a username that contains a domain name when using a TACACS+ server to authenticate, (2) when a new SSH session is in the login phase and a currently logged in user issues a send command, or (3) when IOS is logging messages and an SSH session is terminated while the server is sending data.
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-2004-0081 23 4d, Apple, Avaya and 20 more 67 Webstar, Mac Os X, Mac Os X Server and 64 more 2026-04-16 N/A
OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.
CVE-2005-0196 1 Cisco 1 Ios 2026-04-16 N/A
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-2003-1398 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 12.0 through 12.2, when IP routing is disabled, accepts false ICMP redirect messages, which allows remote attackers to cause a denial of service (network routing modification).
CVE-2006-3906 1 Cisco 21 Adaptive Security Appliance Software, Ios, Pix Asa Ids and 18 more 2026-04-16 N/A
Internet Key Exchange (IKE) version 1 protocol, as implemented on Cisco IOS, VPN 3000 Concentrators, and PIX firewalls, allows remote attackers to cause a denial of service (resource exhaustion) via a flood of IKE Phase-1 packets that exceed the session expiration rate. NOTE: it has been argued that this is due to a design weakness of the IKE version 1 protocol, in which case other vendors and implementations would also be affected.
CVE-2006-0485 1 Cisco 1 Ios 2026-04-16 N/A
The TCL shell in Cisco IOS 12.2(14)S before 12.2(14)S16, 12.2(18)S before 12.2(18)S11, and certain other releases before 25 January 2006 does not perform Authentication, Authorization, and Accounting (AAA) command authorization checks, which may allow local users to execute IOS EXEC commands that were prohibited via the AAA configuration, aka Bug ID CSCeh73049.
