CVE-1999-0162 1 Cisco 1 Ios 2026-04-16 5.0 MEDIUM N/A
The "established" keyword in some Cisco IOS software allowed an attacker to bypass filtering.
CVE-2003-0732 1 Cisco 4 Ciscoworks Cd1, Ciscoworks Common Management Foundation, Resource Manager and 1 more 2026-04-16 10.0 HIGH N/A
CiscoWorks Common Management Foundation (CMF) 2.1 and earlier allows the guest user to obtain restricted information and possibly gain administrative privileges by changing the "guest" user to the Admin user on the Modify or delete users pages.
CVE-2005-3774 1 Cisco 1 Pix 2026-04-16 5.0 MEDIUM 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-2006-3290 1 Cisco 1 Wireless Control System 2026-04-16 5.0 MEDIUM N/A
HTTP server in Cisco Wireless Control System (WCS) for Linux and Windows before 3.2(51) stores sensitive information under the web root with insufficient access control, which allows remote attackers to obtain usernames and directory paths via a direct URL request.
CVE-2001-0750 1 Cisco 1 Ios 2026-04-16 5.0 MEDIUM 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-2000-1027 1 Cisco 1 Pix Firewall Software 2026-04-16 5.0 MEDIUM N/A
Cisco Secure PIX Firewall 5.2(2) allows remote attackers to determine the real IP address of a target FTP server by flooding the server with PASV requests, which includes the real IP address in the response when passive mode is established.
CVE-2000-0613 1 Cisco 1 Pix Firewall 2026-04-16 5.0 MEDIUM 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-2006-3594 1 Cisco 1 Unified Callmanager 2026-04-16 7.5 HIGH N/A
Buffer overflow in Cisco Unified CallManager (CUCM) 5.0(1) through 5.0(3a) allows remote attackers to execute arbitrary code via a long hostname in a SIP request, aka bug CSCsd96542.
CVE-2005-3788 1 Cisco 1 Adaptive Security Appliance Software 2026-04-16 5.4 MEDIUM 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-2002-2379 1 Cisco 1 As5350 2026-04-16 7.8 HIGH N/A
Cisco AS5350 IOS 12.2(11)T with access control lists (ACLs) applied and possibly with ssh running allows remote attackers to cause a denial of service (crash) via a port scan, possibly due to an ssh bug. NOTE: this issue could not be reproduced by the vendor
CVE-2002-1106 1 Cisco 1 Vpn Client 2026-04-16 7.5 HIGH N/A
Cisco Virtual Private Network (VPN) Client software 2.x.x, and 3.x before 3.5.1C, does not properly verify that certificate DN fields match those of the certificate from the VPN Concentrator, which allows remote attackers to conduct man-in-the-middle attacks.
CVE-2005-4332 1 Cisco 1 Network Admission Control Manager And Server System Software 2026-04-16 9.4 HIGH 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 or upload files via direct requests to obsolete JSP files including (1) admin/uploadclient.jsp, (2) apply_firmware_action.jsp, and (3) file.jsp.
CVE-2004-0551 1 Cisco 24 Catalyst 2901, Catalyst 2902, Catalyst 2926 and 21 more 2026-04-16 5.0 MEDIUM 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-2001-0752 1 Cisco 1 Cbos 2026-04-16 5.0 MEDIUM N/A
Cisco CBOS 2.3.8 and earlier allows remote attackers to cause a denial of service via an ICMP ECHO REQUEST (ping) with the IP Record Route option set.
CVE-2001-0863 1 Cisco 1 12000 Router 2026-04-16 5.0 MEDIUM 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-2005-2681 1 Cisco 1 Ips Sensor Software 2026-04-16 7.2 HIGH 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-2005-2631 1 Cisco 1 Network Admission Control Manager And Server System Software 2026-04-16 7.5 HIGH 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.
CVE-2004-0307 1 Cisco 1 Optical Networking Systems Software 2026-04-16 5.0 MEDIUM N/A
Cisco ONS 15327 before 4.1(3), ONS 15454 before 4.6(1), and ONS 15454 SD before 4.1(3) allows remote attackers to cause a denial of service (reset) by not sending the ACK portion of the TCP three-way handshake and sending an invalid response instead.
CVE-2003-0647 1 Cisco 1 Ios 2026-04-16 7.5 HIGH N/A
Buffer overflow in the HTTP server for Cisco IOS 12.2 and earlier allows remote attackers to execute arbitrary code via an extremely long (2GB) HTTP GET request.
CVE-2005-3886 1 Cisco 1 Security Agent 2026-04-16 7.2 HIGH N/A
Unspecified vulnerability in Cisco Security Agent (CSA) 4.5.0 and 4.5.1 agents, when running on Windows systems, allows local users to bypass protections and gain system privileges by executing certain local software.
