CVE-1999-0775 1 Cisco 1 Ios 2025-04-03 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-2000-0268 1 Cisco 12 3660 Router, 7100 Router, 7200 Router and 9 more 2025-04-03 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-1999-0016 6 Cisco, Gnu, Hp and 3 more 8 Ios, Inet, Hp-ux and 5 more 2025-04-03 N/A
Land IP denial of service.
CVE-1999-0063 1 Cisco 1 Ios 2025-04-03 N/A
Cisco IOS 12.0 and other versions can be crashed by malicious UDP packets to the syslog port.
CVE-1999-0162 1 Cisco 1 Ios 2025-04-03 N/A
The "established" keyword in some Cisco IOS software allowed an attacker to bypass filtering.
CVE-1999-0157 1 Cisco 2 Ios, Pix Firewall Software 2025-04-03 N/A
Cisco PIX firewall and CBAC IP fragmentation attack results in a denial of service.
CVE-1999-0160 1 Cisco 1 Ios 2025-04-03 N/A
Some classic Cisco IOS devices have a vulnerability in the PPP CHAP authentication to establish unauthorized PPP connections.
CVE-1999-0161 1 Cisco 1 Ios 2025-04-03 N/A
In Cisco IOS 10.3, with the tacacs-ds or tacacs keyword, an extended IP access control list could bypass filtering.
CVE-1999-0293 1 Cisco 1 Ios 2025-04-03 N/A
AAA authentication on Cisco systems allows attackers to execute commands without authorization.
CVE-2006-3906 1 Cisco 21 Adaptive Security Appliance Software, Ios, Pix Asa Ids and 18 more 2025-04-03 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-1999-1465 1 Cisco 1 Ios 2025-04-03 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-2001-0711 1 Cisco 1 Ios 2025-04-03 N/A
Cisco IOS 11.x and 12.0 with ATM support allows attackers to cause a denial of service via the undocumented Interim Local Management Interface (ILMI) SNMP community string.
CVE-1999-1306 1 Cisco 1 Ios 2025-04-03 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-2001-0750 1 Cisco 1 Ios 2025-04-03 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-1999-0524 11 Apple, Cisco, Hp and 8 more 14 Mac Os X, Macos, Ios and 11 more 2025-04-03 N/A
ICMP information such as (1) netmask and (2) timestamp is allowed from arbitrary hosts.
CVE-2002-1358 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2025-04-03 N/A
Multiple SSH2 servers and clients do not properly handle lists with empty elements or strings, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code, as demonstrated by the SSHredder SSH protocol test suite.
CVE-2001-0288 1 Cisco 1 Ios 2025-04-03 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-2004-0079 23 4d, Apple, Avaya and 20 more 67 Webstar, Mac Os X, Mac Os X Server and 64 more 2025-04-03 7.5 High
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.
CVE-2001-0537 1 Cisco 1 Ios 2025-04-03 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-2003-0567 1 Cisco 3 Ios, Ons 15454 Optical Transport Platform, Optical Networking Systems Software 2025-04-03 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.
