Vulnerabilidades

Web Extender Client (WEC) in Microsoft Office 2000, Windows 2000, and Windows Me does not properly process Internet Explorer security settings for NTLM authentication, which allows attackers to obtain NTLM credentials and possibly obtain the password, aka the "Web Client NTLM Authentication" vulnerability.

Remote Data Protocol (RDP) in Windows 2000 Terminal Service does not properly handle certain malformed packets, which allows remote attackers to cause a denial of service, aka the "Invalid RDP Data" vulnerability.

Buffer overflow in Microsoft Phone Book Service allows local users to execute arbitrary commands, aka the "Phone Book Service Buffer Overflow" vulnerability.

Telnet Service for Windows 2000 Professional does not properly terminate incomplete connection attempts, which allows remote attackers to cause a denial of service by connecting to the server and not providing any input.

Windows NT 4.0 and Windows 2000 hosts allow remote attackers to cause a denial of service (unavailable connections) by sending multiple SMB SMBnegprots requests but not reading the response that is sent back.

Buffer overflows in Microsoft Network Monitor (Netmon) allow remote attackers to execute arbitrary commands via a long Browser Name in a CIFS Browse Frame, a long SNMP community name, or a long username or filename in an SMB session, aka the "Netmon Protocol Parsing" vulnerability. NOTE: It is highly likely that this…

The Input Method Editor (IME) in the Simplified Chinese version of Windows 2000 does not disable access to privileged functionality that should normally be restricted, which allows local users to gain privileges, aka the "Simplified Chinese IME State Recognition" vulnerability.

Buffer overflow in the System Monitor ActiveX control in Windows 2000 allows remote attackers to execute arbitrary commands via a long LogFileName parameter in HTML source code, aka the "ActiveX Parameter Validation" vulnerability.

Microsoft Windows 2000 before Service Pack 2 (SP2), when running in a non-Windows 2000 domain and using NTLM authentication, and when credentials of an account are locally cached, allows local users to bypass account lockout policies and make an unlimited number of login attempts, aka the "Domain Account Lockout"…

Buffer overflow in the Still Image Service in Windows 2000 allows local users to gain additional privileges via a long WM_USER message, aka the "Still Image Service Privilege Escalation" vulnerability.

The Windows 2000 telnet client attempts to perform NTLM authentication by default, which allows remote attackers to capture and replay the NTLM challenge/response via a telnet:// URL that points to the malicious server, aka the "Windows 2000 Telnet Client NTLM Authentication" vulnerability.

The web-based folder display capability in Microsoft Internet Explorer 5.5 on Windows 98 allows local users to insert Trojan horse programs by modifying the Folder.htt file and using the InvokeVerb method in the ShellDefView ActiveX control to specify a default execute option for the first file that is listed in the…

Microsoft Windows 2000 allows local users to cause a denial of service by corrupting the local security policy via malformed RPC traffic, aka the "Local Security Policy Corruption" vulnerability.

The Service Control Manager (SCM) in Windows 2000 creates predictable named pipes, which allows a local user with console access to gain administrator privileges, aka the "Service Control Manager Named Pipe Impersonation" vulnerability.

Interactions between the CIFS Browser Protocol and NetBIOS as implemented in Microsoft Windows 95, 98, NT, and 2000 allow remote attackers to modify dynamic NetBIOS name cache entries via a spoofed Browse Frame Request in a unicast or UDP broadcast datagram.

The NetBIOS Name Server (NBNS) protocol does not perform authentication, which allows remote attackers to cause a denial of service by sending a spoofed Name Conflict or Name Release datagram, aka the "NetBIOS Name Server Protocol Spoofing" vulnerability.

The registry entry for the Windows Shell executable (Explorer.exe) in Windows NT and Windows 2000 uses a relative path name, which allows local users to execute arbitrary commands by inserting a Trojan Horse named Explorer.exe into the %Systemdrive% directory, aka the "Relative Shell Path" vulnerability.

A Windows NT administrator account has the default name of Administrator.

Windows 2000 Server allows remote attackers to cause a denial of service by sending a continuous stream of binary zeros to various TCP and UDP ports, which significantly increases the CPU utilization.

Windows 2000 Telnet Server allows remote attackers to cause a denial of service by sending a continuous stream of binary zeros, which causes the server to crash.

Windows 2000 allows a local user process to access another user's desktop within the same windows station, aka the "Desktop Separation" vulnerability.

Windows NT and Windows 2000 hosts allow a remote attacker to cause a denial of service via malformed DCE/RPC SMBwriteX requests that contain an invalid data length.

A system does not present an appropriate legal message or warning to a user who is accessing it.

The Protected Store in Windows 2000 does not properly select the strongest encryption when available, which causes it to use a default of 40-bit encryption instead of 56-bit DES encryption, aka the "Protected Store Key Length" vulnerability.

The CIFS Computer Browser service allows remote attackers to cause a denial of service by sending a ResetBrowser frame to the Master Browser, aka the "ResetBrowser Frame" vulnerability.
