CVE-2001-0427 1 Cisco 6 Vpn 3000 Concentrator, Vpn 3005 Concentrator, Vpn 3015 Concentrator and 3 more 2026-04-16 N/A
Cisco VPN 3000 series concentrators before 2.5.2(F) allow remote attackers to cause a denial of service via a flood of invalid login requests to (1) the SSL service, or (2) the telnet service, which do not properly disconnect the user after several failed login attempts.
CVE-2005-3788 1 Cisco 1 Adaptive Security Appliance Software 2026-04-16 N/A
Race condition in Cisco Adaptive Security Appliance (ASA) 7.0(0), 7.0(2), and 7.0(4), when running with an Active/Standby configuration and when the failover LAN interface fails, allows remote attackers to cause a denial of service (standby firewall failure) by sending spoofed ARP responses from an IP address of an active firewall, which prevents the standby firewall from becoming active, aka "failover denial of service."
CVE-2005-3669 1 Cisco 8 Adaptive Security Appliance Software, Firewall Services Module, Ios and 5 more 2026-04-16 N/A
Multiple unspecified vulnerabilities in the Internet Key Exchange version 1 (IKEv1) implementation in multiple Cisco products allow remote attackers to cause a denial of service (device reset) via certain malformed IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the Cisco advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to.
CVE-2006-2679 1 Cisco 1 Vpn Client 2026-04-16 N/A
Unspecified vulnerability in the VPN Client for Windows Graphical User Interface (GUI) (aka the VPN client dialer) in Cisco VPN Client for Windows 4.8.00.* and earlier, except for 4.7.00.0533, allows local authenticated, interactive users to gain privileges, possibly due to privileges of dialog boxes, aka bug ID CSCsd79265.
CVE-2001-0861 1 Cisco 1 12000 Router 2026-04-16 N/A
Cisco 12000 with IOS 12.0 and line cards based on Engine 2 and earlier allows remote attackers to cause a denial of service (CPU consumption) by flooding the router with traffic that generates a large number of ICMP Unreachable replies.
CVE-1999-1100 1 Cisco 1 Pix Private Link 2026-04-16 N/A
Cisco PIX Private Link 4.1.6 and earlier does not properly process certain commands in the configuration file, which reduces the effective key length of the DES key to 48 bits instead of 56 bits, which makes it easier for an attacker to find the proper key via a brute force attack.
CVE-2001-0161 1 Cisco 1 Aironet 2026-04-16 N/A
Cisco 340-series Aironet access point using firmware 11.01 does not use 6 of the 24 available IV bits for WEP encryption, which makes it easier for remote attackers to mount brute force attacks.
CVE-2005-3426 1 Cisco 1 Content Services Switch 11500 2026-04-16 N/A
Cisco CSS 11500 Content Services Switch (CSS) with SSL termination services allows remote attackers to cause a denial of service (memory corruption and device reload) via a malformed client certificate during SSL session negotiation.
CVE-2000-0380 1 Cisco 1 Ios 2026-04-16 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-2000-0945 1 Cisco 1 Catalyst 3500 Xl 2026-04-16 N/A
The web configuration interface for Catalyst 3500 XL switches allows remote attackers to execute arbitrary commands without authentication when the enable password is not set, via a URL containing the /exec/ directory.
CVE-2004-1164 1 Cisco 1 Cns Network Registrar 2026-04-16 N/A
The lock manager in Cisco CNS Network Registrar 6.0 through 6.1.1.3 allows remote attackers to cause a denial of service (process crash) via a certain "unexpected packet sequence."
CVE-2005-3427 1 Cisco 1 Ciscoworks Management Center For Ips Sensors 2026-04-16 N/A
The Cisco Management Center (MC) for IPS Sensors (IPS MC) 2.1 can omit port field values while generating the Cisco IOS IPS configuration file, wich can cause some signatures to be disabled and makes it easier for attackers to escape detection.
CVE-1999-1129 1 Cisco 2 Catalyst 2900 Vlan, Ios 2026-04-16 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-2005-2681 1 Cisco 1 Ips Sensor Software 2026-04-16 N/A
Unspecified vulnerability in the command line processing (CLI) logic in Cisco Intrusion Prevention System 5.0(1) and 5.0(2) allows local users with OPERATOR or VIEWER privileges to gain additional privileges via unknown vectors.
CVE-2001-0288 1 Cisco 1 Ios 2026-04-16 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-2001-1434 1 Cisco 1 Ios 2026-04-16 N/A
Cisco IOS 12.0(5)XU through 12.1(2) allows remote attackers to read system administration and topology information via an "snmp-server host" command, which creates a readable "community" community string if one has not been previously created.
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-2002-0954 1 Cisco 1 Pix Firewall 2026-04-16 N/A
The encryption algorithms for enable and passwd commands on Cisco PIX Firewall can be executed quickly due to a limited number of rounds, which make it easier for an attacker to decrypt the passwords using brute force techniques.
CVE-2005-2631 1 Cisco 1 Network Admission Control Manager And Server System Software 2026-04-16 N/A
Cisco Clean Access (CCA) 3.3.0 to 3.3.9, 3.4.0 to 3.4.5, and 3.5.0 to 3.5.3 does not properly authenticate users when invoking API methods, which could allow remote attackers to bypass security checks, change the assigned role of a user, or disconnect users.
