CVE-2002-0769 1 Cisco 1 Ata-186 2025-04-03 6.4 MEDIUM N/A
The web-based configuration interface for the Cisco ATA 186 Analog Telephone Adaptor allows remote attackers to bypass authentication via an HTTP POST request with a single byte, which allows the attackers to (1) obtain the password from the login screen, or (2) reconfigure the adaptor by modifying certain request parameters.
CVE-2005-3481 1 Cisco 1 Ios 2025-04-03 9.3 HIGH N/A
Cisco IOS 12.0 to 12.4 might allow remote attackers to execute arbitrary code via a heap-based buffer overflow in system timers. NOTE: this issue does not correspond to a specific vulnerability, rather a general weakness that only increases the feasibility of exploitation of any vulnerabilities that might exist. Such design-level weaknesses normally are not included in CVE, so perhaps this issue should be REJECTed.
CVE-2001-0566 1 Cisco 1 Catalyst 2900 2025-04-03 5.0 MEDIUM N/A
Cisco Catalyst 2900XL switch allows a remote attacker to create a denial of service via an empty UDP packet sent to port 161 (SNMP) when SNMP is disabled.
CVE-2001-0427 1 Cisco 6 Vpn 3000 Concentrator, Vpn 3005 Concentrator, Vpn 3015 Concentrator and 3 more 2025-04-03 7.1 HIGH 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-2005-0612 1 Cisco 7 Ipvc-3510-mcu, Ipvc-3520-gw-2b, Ipvc-3520-gw-2b2v and 4 more 2025-04-03 7.5 HIGH N/A
Cisco IP/VC Videoconferencing System 3510, 3520, 3525 and 3530 contain hard-coded default SNMP community strings, which allows remote attackers to gain access, cause a denial of service, and modify configuration.
CVE-1999-0159 1 Cisco 1 Ios 2025-04-03 5.0 MEDIUM N/A
Attackers can crash a Cisco IOS router or device, provided they can get to an interactive prompt (such as a login). This applies to some IOS 9.x, 10.x, and 11.x releases.
CVE-2002-0241 1 Cisco 1 Secure Access Control Server 2025-04-03 7.5 HIGH N/A
NDSAuth.DLL in Cisco Secure Authentication Control Server (ACS) 3.0.1 does not check the Expired or Disabled state of users in the Novell Directory Services (NDS), which could allow those users to authenticate to the server.
CVE-2000-1055 1 Cisco 1 Secure Access Control Server 2025-04-03 10.0 HIGH N/A
Buffer overflow in CiscoSecure ACS Server 2.4(2) and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary commands via a large TACACS+ packet.
CVE-2002-0545 1 Cisco 2 Aironet Ap340, Aironet Ap350 2025-04-03 5.0 MEDIUM N/A
Cisco Aironet before 11.21 with Telnet enabled allows remote attackers to cause a denial of service (reboot) via a series of login attempts with invalid usernames and passwords.
CVE-2001-0650 1 Cisco 1 Ios 2025-04-03 5.0 MEDIUM N/A
Cisco devices IOS 12.0 and earlier allow a remote attacker to cause a crash, or bad route updates, via malformed BGP updates with unrecognized transitive attribute.
CVE-2002-0813 1 Cisco 1 Ios 2025-04-03 7.1 HIGH N/A
Heap-based buffer overflow in the TFTP server capability in Cisco IOS 11.1, 11.2, and 11.3 allows remote attackers to cause a denial of service (reset) or modify configuration via a long filename.
CVE-2001-1038 1 Cisco 1 Sn 5420 Storage Router Firmware 2025-04-03 5.0 MEDIUM N/A
Cisco SN 5420 Storage Router 1.1(3) and earlier allows remote attackers to cause a denial of service (reboot) via a series of connections to TCP port 8023.
CVE-2004-1432 1 Cisco 1 Optical Networking Systems Software 2025-04-03 5.0 MEDIUM N/A
Multiple versions of Cisco ONS 15327, ONS 15454, and ONS 15454 SDH, including 4.6(0) and 4.6(1), 4.5(x), 4.1(0) to 4.1(3), 4.0(0) to 4.0(2), and earlier versions, allows remote attackers to cause a denial of service (control card reset) via malformed (1) IP or (2) ICMP packets.
CVE-1999-0430 1 Cisco 3 Catalyst 12xx Supervisor Software, Catalyst 29xx Supervisor Software, Catalyst 5xxx Supervisor Software 2025-04-03 5.0 MEDIUM N/A

Cisco IOS 12.2 through 12.4 before 20060920, as used by Cisco IAD2430, IAD2431, and IAD2432 Integrated Access Devices, the VG224 Analog Phone Gateway, and the MWR 1900 and 1941 Mobile Wireless Edge Routers, is incorrectly identified as supporting DOCSIS, which allows remote attackers to gain read-write access via a hard-coded cable-docsis community string and read or modify arbitrary SNMP variables.
CVE-2006-4430 1 Cisco 2 Network Admission Control, Network Admission Control Manager And Server System Software 2025-04-03 5.0 MEDIUM N/A
The Cisco Network Admission Control (NAC) 3.6.4.1 and earlier allows remote attackers to prevent installation of the Cisco Clean Access (CCA) Agent and bypass local and remote protection mechanisms by modifying (1) the HTTP User-Agent header or (2) the behavior of the TCP/IP stack. NOTE: the vendor has disputed the severity of this issue, stating that users cannot bypass authentication mechanisms.
