CVE-2002-1556 1 Cisco 1 Optical Networking Systems Software 2026-04-16 N/A
Cisco ONS15454 and ONS15327 running ONS before 3.4 allows attackers to cause a denial of service (reset) via an HTTP request to the TCC, TCC+ or XTC, in which the request contains an invalid CORBA Interoperable Object Reference (IOR).
CVE-2006-4312 1 Cisco 9 Adaptive Security Appliance, Pix Firewall 501, Pix Firewall 506 and 6 more 2026-04-16 N/A
Cisco PIX 500 Series Security Appliances and ASA 5500 Series Adaptive Security Appliances, when running 7.0(x) up to 7.0(5) and 7.1(x) up to 7.1(2.4), and Firewall Services Module (FWSM) 3.1(x) up to 3.1(1.6), causes the EXEC password, local user passwords, and the enable password to be changed to a "non-random value" under certain circumstances, which causes administrators to be locked out and might allow attackers to gain access.
CVE-2002-0545 1 Cisco 2 Aironet Ap340, Aironet Ap350 2026-04-16 N/A
Cisco Aironet before 11.21 with Telnet enabled allows remote attackers to cause a denial of service (reboot) via a series of login attempts with invalid usernames and passwords.

Denial of service in Cisco routers running NAT via a PORT command from an FTP client to a Telnet port.
CVE-2002-2208 2 Cisco, Extended Interior Gateway Routing Protocol 2 Ios, Extended Interior Gateway Routing Protocol 2026-04-16 N/A
Extended Interior Gateway Routing Protocol (EIGRP), as implemented in Cisco IOS 11.3 through 12.2 and other products, allows remote attackers to cause a denial of service (flood) by sending a large number of spoofed EIGRP neighbor announcements, which results in an ARP storm on the local network.
CVE-2005-4499 1 Cisco 21 Adaptive Security Appliance Software, Pix Asa Ids, Pix Firewall and 18 more 2026-04-16 N/A
The Downloadable RADIUS ACLs feature in Cisco PIX and VPN 3000 concentrators, when creating an ACL on the Cisco Secure Access Control Server (CS ACS), generates a random internal name for an ACL that is also used as a hidden user name and password, which allows remote attackers to gain privileges by sniffing the username from the cleartext portion of a RADIUS session, then using the password to log in to another device that uses CS ACS.
CVE-2006-3287 1 Cisco 1 Wireless Control System 2026-04-16 N/A
Cisco Wireless Control System (WCS) for Linux and Windows 4.0(1) and earlier uses a default administrator username "root" and password "public," which allows remote attackers to gain access (aka bug CSCse21391).
CVE-2005-2451 1 Cisco 2 Ios, Ios Xr 2026-04-16 N/A
Cisco IOS 12.0 through 12.4 and IOS XR before 3.2, with IPv6 enabled, allows remote attackers on a local network segment to cause a denial of service (device reload) and possibly execute arbitrary code via a crafted IPv6 packet.
CVE-2004-0551 1 Cisco 24 Catalyst 2901, Catalyst 2902, Catalyst 2926 and 21 more 2026-04-16 N/A
Cisco CatOS 5.x before 5.5(20) through 8.x before 8.2(2) and 8.3(2)GLX, as used in Catalyst switches, allows remote attackers to cause a denial of service (system crash and reload) by sending invalid packets instead of the final ACK portion of the three-way handshake to the (1) Telnet, (2) HTTP, or (3) SSH services, aka "TCP-ACK DoS attack."
CVE-2005-4258 1 Cisco 71 Catalyst, Catalyst 1200 Series, Catalyst 1900 Series and 68 more 2026-04-16 N/A
Unspecified Cisco Catalyst Switches allow remote attackers to cause a denial of service (device crash) via an IP packet with the same source and destination IPs and ports, and with the SYN flag set (aka LanD). NOTE: the provenance of this issue is unknown; the details are obtained solely from the BID.
CVE-2002-2052 1 Cisco 1 Ios 2026-04-16 N/A
Cisco 2611 router running IOS 12.1(6.5), possibly an interim release, allows remote attackers to cause a denial of service via port scans such as (1) scanning all ports on a single host and (2) scanning a network of hosts for a single open port through the router. NOTE: the vendor could not reproduce this issue, saying that the original reporter was using an interim release of the software.
CVE-2002-1102 1 Cisco 2 Vpn 3000 Concentrator Series Software, Vpn 3002 Hardware Client 2026-04-16 N/A
The LAN-to-LAN IPSEC capability for Cisco VPN 3000 Concentrator 2.2.x, and 3.x before 3.5.4, allows remote attackers to cause a denial of service via an incoming LAN-to-LAN connection with an existing security association with another device on the remote network, which causes the concentrator to remove the previous connection.
CVE-2005-3774 1 Cisco 1 Pix 2026-04-16 N/A
Cisco PIX 6.3 and 7.0 allows remote attackers to cause a denial of service (blocked new connections) via spoofed TCP packets that cause the PIX to create embryonic connections that that would not produce a valid connection with the end system, including (1) SYN packets with invalid checksums, which do not result in a RST; or, from an external interface, (2) one byte of "meaningless data," or (3) a TTL that is one less than needed to reach the internal destination.
CVE-2006-4352 1 Cisco 1 Content Services Switch 11000 2026-04-16 N/A
The ArrowPoint cookie functionality for Cisco 11000 series Content Service Switches specifies an internal IP address if the administrator does not specify a string option, which allows remote attackers to obtain sensitive information.
CVE-2000-0150 2 Checkpoint, Cisco 2 Firewall-1, Pix Firewall Software 2026-04-16 N/A
Check Point Firewall-1 allows remote attackers to bypass port access restrictions on an FTP server by forcing it to send malicious packets that Firewall-1 misinterprets as a valid 227 response to a client's PASV attempt.
CVE-2002-0882 1 Cisco 2 Skinny Client Control Protocol Software, Voip Phone Cp-7940 2026-04-16 N/A
The web server for Cisco IP Phone (VoIP) models 7910, 7940, and 7960 allows remote attackers to cause a denial of service (reset) and possibly read sensitive memory via a large integer value in (1) the stream ID of the StreamingStatistics script, or (2) the port ID of the PortInformation script.
CVE-2004-0589 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 11.1(x) through 11.3(x) and 12.0(x) through 12.2(x), when configured for BGP routing, allows remote attackers to cause a denial of service (device reload) via malformed BGP (1) OPEN or (2) UPDATE messages.
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-2005-3921 1 Cisco 1 Ios 2026-04-16 N/A
Cross-site scripting (XSS) vulnerability in Cisco IOS Web Server for IOS 12.0(2a) allows remote attackers to inject arbitrary web script or HTML by (1) packets containing HTML that an administrator views via an HTTP interface to the contents of memory buffers, as demonstrated by the URI /level/15/exec/-/buffers/assigned/dump; or (2) sending the router Cisco Discovery Protocol (CDP) packets with HTML payload that an administrator views via the CDP status pages. NOTE: these vectors were originally reported as being associated with the dump and packet options in /level/15/exec/-/show/buffers.
CVE-2001-0711 1 Cisco 1 Ios 2026-04-16 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.
