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-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-1999-1129 1 Cisco 2 Catalyst 2900 Vlan, Ios 2025-04-03 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-1999-1175 1 Cisco 1 Ios 2025-04-03 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-1999-1464 1 Cisco 1 Ios 2025-04-03 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-1999-1465 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-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-2000-0345 1 Cisco 7 Ios, Router 2500, Router 2600 and 4 more 2025-04-03 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-2000-0368 1 Cisco 1 Ios 2025-04-03 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-2000-0380 1 Cisco 1 Ios 2025-04-03 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-2000-0486 1 Cisco 2 Ios, Tacacs\+ 2025-04-03 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-2006-4650 1 Cisco 1 Ios 2025-04-03 N/A
Cisco IOS 12.0, 12.1, and 12.2, when GRE IP tunneling is used and the RFC2784 compliance fixes are missing, does not verify the offset field of a GRE packet during decapsulation, which leads to an integer overflow that references data from incorrect memory locations, which allows remote attackers to inject crafted packets into the routing queue, possibly bypassing intended router ACLs.
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-2006-0485 1 Cisco 1 Ios 2025-04-03 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-2006-0340 1 Cisco 1 Ios 2025-04-03 N/A
Unspecified vulnerability in Stack Group Bidding Protocol (SGBP) support in Cisco IOS 12.0 through 12.4 running on various Cisco products, when SGBP is enabled, allows remote attackers on the local network to cause a denial of service (device hang and network traffic loss) via a crafted UDP packet to port 9900.
