CVE-2000-0380 1 Cisco 1 Ios 2024-11-20 7.1 HIGH 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-2000-0368 1 Cisco 1 Ios 2024-11-20 2.1 LOW 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-2000-0345 1 Cisco 7 Ios, Router 2500, Router 2600 and 4 more 2024-11-20 2.1 LOW 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-2000-0268 1 Cisco 12 3660 Router, 7100 Router, 7200 Router and 9 more 2024-11-20 5.0 MEDIUM 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-1999-1466 1 Cisco 1 Ios 2024-11-20 7.5 HIGH N/A
Vulnerability in Cisco routers versions 8.2 through 9.1 allows remote attackers to bypass access control lists when extended IP access lists are used on certain interfaces, the IP route cache is enabled, and the access list uses the "established" keyword.
CVE-1999-1465 1 Cisco 1 Ios 2024-11-20 7.5 HIGH 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-1999-1464 1 Cisco 1 Ios 2024-11-20 7.5 HIGH N/A
Vulnerability in Cisco IOS 11.1CC and 11.1CT with distributed fast switching (DFS) enabled allows remote attackers to bypass certain access control lists when the router switches traffic from a DFS-enabled interface to an interface that does not have DFS enabled, as described by Cisco bug CSCdk35564.
CVE-1999-1306 1 Cisco 1 Ios 2024-11-20 7.5 HIGH 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-1999-1175 1 Cisco 1 Ios 2024-11-20 7.5 HIGH N/A
Web Cache Control Protocol (WCCP) in Cisco Cache Engine for Cisco IOS 11.2 and earlier does not use authentication, which allows remote attackers to redirect HTTP traffic to arbitrary hosts via WCCP packets to UDP port 2048.
CVE-1999-1129 1 Cisco 2 Catalyst 2900 Vlan, Ios 2024-11-20 7.5 HIGH N/A
Cisco Catalyst 2900 Virtual LAN (VLAN) switches allow remote attackers to inject 802.1q frames into another VLAN by forging the VLAN identifier in the trunking tag.
CVE-1999-0775 1 Cisco 1 Ios 2024-11-20 10.0 HIGH 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-1999-0445 1 Cisco 1 Ios 2024-11-20 5.0 MEDIUM 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-1999-0293 1 Cisco 1 Ios 2024-11-20 7.5 HIGH N/A
AAA authentication on Cisco systems allows attackers to execute commands without authorization.
CVE-1999-0230 1 Cisco 1 Ios 2024-11-20 5.0 MEDIUM N/A
Buffer overflow in Cisco 7xx routers through the telnet service.
CVE-1999-0162 1 Cisco 1 Ios 2024-11-20 5.0 MEDIUM N/A
The "established" keyword in some Cisco IOS software allowed an attacker to bypass filtering.
CVE-1999-0161 1 Cisco 1 Ios 2024-11-20 7.5 HIGH N/A
In Cisco IOS 10.3, with the tacacs-ds or tacacs keyword, an extended IP access control list could bypass filtering.
CVE-1999-0160 1 Cisco 1 Ios 2024-11-20 7.5 HIGH N/A
Some classic Cisco IOS devices have a vulnerability in the PPP CHAP authentication to establish unauthorized PPP connections.
CVE-1999-0159 1 Cisco 1 Ios 2024-11-20 5.0 MEDIUM N/A
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-1999-0157 1 Cisco 2 Ios, Pix Firewall Software 2024-11-20 5.0 MEDIUM N/A
Cisco PIX firewall and CBAC IP fragmentation attack results in a denial of service.
