| CVE-2007-5651 | | 0.00 | — | 0.01 | | Oct 23, 2007 | Unspecified vulnerability in the Extensible Authentication Protocol (EAP) implementation in Cisco IOS 12.3 and 12.4 on Cisco Access Points and 1310 Wireless Bridges (Wireless EAP devices), IOS 12.1 and 12.2 on Cisco switches (Wired EAP devices), and CatOS 6.x through 8.x on Cisco switches allows remote attackers to cause a denial of service (device reload) via a crafted EAP Response Identity packet. |
| CVE-2007-5134 | | 0.00 | — | 0.01 | | Sep 27, 2007 | Cisco Catalyst 6500 and Cisco 7600 series devices use 127/8 IP addresses for Ethernet Out-of-Band Channel (EOBC) internal communication, which might allow remote attackers to send packets to an interface for which network exposure was unintended. |
| CVE-2005-4258 | | 0.00 | — | 0.01 | | Dec 15, 2005 | 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-2004-1775 | | 0.00 | — | 0.04 | | Dec 31, 2004 | Cisco VACM (View-based Access Control MIB) for Catalyst Operating Software (CatOS) 5.5 and 6.1 and IOS 12.0 and 12.1 allows remote attackers to read and modify device configuration via the read-write community string. |
| CVE-2004-0551 | | 0.00 | — | 0.01 | | Aug 6, 2004 | 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-2003-1002 | | 0.00 | — | 0.01 | | Jan 5, 2004 | Cisco Firewall Services Module (FWSM) in Cisco Catalyst 6500 and 7600 series devices allows remote attackers to cause a denial of service (crash and reload) via an SNMPv3 message when snmp-server is set. |
| CVE-2003-1001 | | 0.00 | — | 0.01 | | Jan 5, 2004 | Buffer overflow in the Cisco Firewall Services Module (FWSM) in Cisco Catalyst 6500 and 7600 series devices allows remote attackers to cause a denial of service (crash and reload) via HTTP auth requests for (1) TACACS+ or (2) RADIUS authentication. |
| CVE-2003-0216 | | 0.00 | — | 0.00 | | May 12, 2003 | Unknown vulnerability in Cisco Catalyst 7.5(1) allows local users to bypass authentication and gain access to the enable mode without a password. |
| CVE-2002-2316 | | 0.00 | — | 0.01 | | Dec 31, 2002 | 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-2002-1024 | | 0.00 | — | 0.05 | | Oct 4, 2002 | Cisco IOS 12.0 through 12.2, when supporting SSH, allows remote attackers to cause a denial of service (CPU consumption) via a large packet that was designed to exploit the SSH CRC32 attack detection overflow (CVE-2001-0144). |
| CVE-2001-1071 | | 0.00 | — | 0.01 | | Oct 9, 2001 | 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-2001-0429 | | 0.00 | — | 0.01 | | Jul 2, 2001 | Cisco Catalyst 5000 series switches 6.1(2) and earlier will forward an 802.1x frame on a Spanning Tree Protocol (STP) blocked port, which causes a network storm and a denial of service. |
