| 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-2001-0650 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Cisco devices IOS 12.0 and earlier allow a remote attacker to cause a crash, or bad route updates, via malformed BGP updates with unrecognized transitive attribute. | ||||
| CVE-2001-0929 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| 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. | ||||
| 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. | ||||
| CVE-2006-0486 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| Certain Cisco IOS releases in 12.2S based trains with maintenance release number 25 and later, 12.3T based trains, and 12.4 based trains reuse a Tcl Shell process across login sessions of different local users on the same terminal if the first user does not use tclquit before exiting, which may cause subsequent local users to execute unintended commands or bypass AAA command authorization checks, aka Bug ID CSCef77770. | ||||
| 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-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-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-2000-0486 | 1 Cisco | 2 Ios, Tacacs\+ | 2026-04-16 | N/A |
| Buffer overflow in Cisco TACACS+ tac_plus server allows remote attackers to cause a denial of service via a malformed packet with a long length field. | ||||
| 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-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-1999-0445 | 1 Cisco | 1 Ios | 2026-04-16 | N/A |
| In Cisco routers under some versions of IOS 12.0 running NAT, some packets may not be filtered by input access list filters. | ||||
| 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-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. | ||||
