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 2025-04-03 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 2025-04-03 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 2025-04-03 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 2025-04-03 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 2025-04-03 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 2025-04-03 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 2025-04-03 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 2025-04-03 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.
CVE-2002-2316 1 Cisco 1 Catos 2025-04-03 5.0 MEDIUM 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-2000-0368 1 Cisco 1 Ios 2025-04-03 2.1 LOW 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-2004-0112 24 4d, Apple, Avaya and 21 more 65 Webstar, Mac Os X, Mac Os X Server and 62 more 2025-04-03 5.0 MEDIUM N/A
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.
CVE-2002-2239 1 Cisco 3 Catalyst 6500, Catalyst 7600, Ios 2025-04-03 7.8 HIGH N/A
The Cisco Optical Service Module (OSM) for the Catalyst 6500 and 7600 series running Cisco IOS 12.1(8)E through 12.1(13.4)E allows remote attackers to cause a denial of service (hang) via a malformed packet.
CVE-2006-1928 1 Cisco 1 Ios Xr 2025-04-03 5.0 MEDIUM N/A
Cisco IOS XR, when configured for Multi Protocol Label Switching (MPLS) and running on Cisco CRS-1 routers, allows remote attackers to cause a denial of service (Modular Services Cards (MSC) crash or "MPLS packet handling problems") via certain MPLS packets, as identified by Cisco bug IDs (1) CSCsd15970 and (2) CSCsd55531.
CVE-2001-1071 1 Cisco 2 Catos, Ios 2025-04-03 5.0 MEDIUM N/A
Cisco IOS 12.2 and earlier running Cisco Discovery Protocol (CDP) allows remote attackers to cause a denial of service (memory consumption) via a flood of CDP neighbor announcements.
CVE-2002-1190 1 Cisco 1 Unity Server 2025-04-03 7.5 HIGH N/A
Cisco Unity 2.x and 3.x uses well-known default user accounts, which could allow remote attackers to gain access and place arbitrary calls.
