CVE-2000-0267 1 Cisco 1 Catos 2026-04-16 N/A
Cisco Catalyst 5.4.x allows a user to gain access to the "enable" mode without a password.
CVE-2006-0483 1 Cisco 2 Vpn 3000 Concentrator Series Software, Vpn 3030 Concentator 2026-04-16 N/A
Cisco VPN 3000 series concentrators running software 4.7.0 through 4.7.2.A allow remote attackers to cause a denial of service (device reload or user disconnect) via a crafted HTTP packet.
CVE-2002-2316 1 Cisco 1 Catos 2026-04-16 N/A
Cisco Catalyst 4000 series switches running CatOS 5.5.5, 6.3.5, and 7.1.2 do not always learn MAC addresses from a single initial packet, which causes unicast traffic to be broadcast across the switch and allows remote attackers to obtain sensitive network information by sniffing.
CVE-2006-4775 1 Cisco 2 Catos, Ios 2026-04-16 N/A
The VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(19) and CatOS allows remote attackers to cause a denial of service by sending a VTP update with a revision value of 0x7FFFFFFF, which is incremented to 0x80000000 and is interpreted as a negative number in a signed context.
CVE-2006-4774 1 Cisco 1 Ios 2026-04-16 N/A
The VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(19) allows remote attackers to cause a denial of service by sending a VTP version 1 summary frame with a VTP version field value of 2.
CVE-2001-0865 1 Cisco 1 12000 Router 2026-04-16 N/A
Cisco 12000 with IOS 12.0 and line cards based on Engine 2 does not support the "fragment" keyword in an outgoing ACL, which could allow fragmented packets in violation of the intended access.
CVE-2003-0258 1 Cisco 7 Vpn 3000 Concentrator Series Software, Vpn 3002 Hardware Client, Vpn 3005 Concentrator Software and 4 more 2026-04-16 N/A
Cisco VPN 3000 series concentrators and Cisco VPN 3002 Hardware Client 3.5.x through 4.0.REL, when enabling IPSec over TCP for a port on the concentrator, allow remote attackers to reach the private network without authentication.
CVE-2001-0863 1 Cisco 1 12000 Router 2026-04-16 N/A
Cisco 12000 with IOS 12.0 and line cards based on Engine 2 does not handle the "fragment" keyword in a compiled ACL (Turbo ACL) for packets that are sent to the router, which allows remote attackers to cause a denial of service via a flood of fragments.
CVE-2000-0613 1 Cisco 1 Pix Firewall 2026-04-16 N/A
Cisco Secure PIX Firewall does not properly identify forged TCP Reset (RST) packets, which allows remote attackers to force the firewall to close legitimate connections.
CVE-2001-0862 1 Cisco 1 12000 Router 2026-04-16 N/A
Cisco 12000 with IOS 12.0 and line cards based on Engine 2 does not block non-initial packet fragments, which allows remote attackers to bypass the ACL.
CVE-2001-0861 1 Cisco 1 12000 Router 2026-04-16 N/A

CVE-2005-4825 1 Cisco 1 Network Admission Control Manager And Server System Software 2026-04-16 N/A
Cisco Clean Access 3.5.5 and earlier on the Secure Smart Manager allows remote attackers to bypass authentication and cause a denial of service (disk consumption), or make unauthorized files accessible, by uploading files through requests to certain JSP scripts, a related issue to CVE-2005-4332.
CVE-2006-4194 1 Cisco 8 Pix Firewall 501, Pix Firewall 506, Pix Firewall 515 and 5 more 2026-04-16 N/A
Unspecified vulnerability in Cisco PIX 500 Series Security Appliances allows remote attackers to send arbitrary UDP packets to intranet devices via unspecified vectors involving Session Initiation Protocol (SIP) fixup commands, a different issue than CVE-2006-4032. NOTE: the vendor, after working with the researcher, has been unable to reproduce the issue
CVE-2006-3595 1 Cisco 1 Router Web Setup 2026-04-16 N/A
