OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.
CVE-2006-3287 1 Cisco 1 Wireless Control System 2025-04-03 7.5 HIGH N/A
Cisco Wireless Control System (WCS) for Linux and Windows 4.0(1) and earlier uses a default administrator username "root" and password "public," which allows remote attackers to gain access (aka bug CSCse21391).

Cisco VPN 3000 Concentrator before 4.1.7.F allows remote attackers to determine valid groupnames by sending an IKE Aggressive Mode packet with the groupname in the ID field, which generates a response if the groupname is valid, but does not generate a response for an invalid groupname.
CVE-2002-0908 1 Cisco 1 Ids Device Manager 2025-04-03 5.0 MEDIUM N/A
Directory traversal vulnerability in the web server for Cisco IDS Device Manager before 3.1.2 allows remote attackers to read arbitrary files via a .. (dot dot) in the HTTPS request.
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-2004-1433 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, and ONS 15600 1.x(x), allows remote attackers to cause a denial of service (control card reset) via malformed (1) TCP and (2) UDP packets.
CVE-2002-1189 1 Cisco 1 Unity Server 2025-04-03 4.6 MEDIUM N/A
The default configuration of Cisco Unity 2.x and 3.x does not block international operator calls in the predefined restriction tables, which could allow authenticated users to place international calls using call forwarding.
CVE-2000-0268 1 Cisco 12 3660 Router, 7100 Router, 7200 Router and 9 more 2025-04-03 5.0 MEDIUM N/A
Cisco IOS 11.x and 12.x allows remote attackers to cause a denial of service by sending the ENVIRON option to the Telnet daemon before it is ready to accept it, which causes the system to reboot.
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-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.
CVE-2002-1768 1 Cisco 1 Ios 2025-04-03 5.0 MEDIUM N/A
Cisco IOS 11.1 through 12.2, when HSRP support is not enabled, allows remote attackers to cause a denial of service (CPU consumption) via randomly sized UDP packets to the Hot Standby Routing Protocol (HSRP) port 1985.
CVE-2002-0505 1 Cisco 1 Call Manager 2025-04-03 5.0 MEDIUM N/A
Memory leak in the Call Telephony Integration (CTI) Framework authentication for Cisco CallManager 3.0 and 3.1 before 3.1(3) allows remote attackers to cause a denial of service (crash and reload) via a series of authentication failures, e.g. via incorrect passwords.
CVE-2002-1357 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2025-04-03 10.0 HIGH N/A
Multiple SSH2 servers and clients do not properly handle packets or data elements with incorrect length specifiers, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code, as demonstrated by the SSHredder SSH protocol test suite.
CVE-1999-1100 1 Cisco 1 Pix Private Link 2025-04-03 7.5 HIGH 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-2005-2181 1 Cisco 4 Ip Phone 7940, Ip Phone 7940 Firmware, Ip Phone 7960 and 1 more 2025-04-03 5.0 MEDIUM 7.5 HIGH
Cisco 7940/7960 Voice over IP (VoIP) phones do not properly check the Call-ID, branch, and tag values in a NOTIFY message to verify a subscription, which allows remote attackers to spoof messages such as the "Messages waiting" message.
