Vulnerabilidades

Windows NT TCP/IP processes fragmented IP packets improperly, causing a denial of service.

A system-critical Windows NT file or directory has inappropriate permissions.

A Windows NT account policy does not forcibly disconnect remote users from the server when their logon hours expire.

An event log in Windows NT has inappropriate access permissions.

Windows NT is not using a password filter utility, e.g. PASSFILT.DLL.

A Windows NT system's registry audit policy does not log an event success or failure for security-critical registry keys.

The Forms 2.0 ActiveX control (included with Visual Basic for Applications 5.0) can be used to read text from a user's clipboard when the user accesses documents with ActiveX content.

A Windows NT system's file audit policy does not log an event success or failure for non-critical files or directories.

The default setting for the Winlogon key entry ShutdownWithoutLogon in Windows NT allows users with physical access to shut down a Windows NT system without logging in.

A system-critical Windows NT registry key has an inappropriate value.

A system-critical Windows NT registry key has inappropriate permissions.

Windows NT automatically logs in an administrator upon rebooting.

A Windows NT system does not restrict access to removable media drives such as a floppy disk drive or CDROM drive.

A Windows NT log file has an inappropriate maximum size or retention period.

Windows NT FTP server (WFTP) with the guest account enabled without a password allows an attacker to log into the FTP server using any username and password.

TCP/IP implementation in Microsoft Windows 95, Windows NT 4.0, and possibly others, allows remote attackers to reset connections by forcing a reset (RST) via a PSH ACK or other means, obtaining the target's last sequence number from the resulting packet, then spoofing a reset to the target.

The Windows NT guest account is enabled.

A Windows NT domain user or administrator account has a default, null, blank, or missing password.

A Windows NT domain user or administrator account has a guessable password.

The Windows NT RPC service allows remote attackers to conduct a denial of service using spoofed malformed RPC packets which generate an error message that is sent to the spoofed host, potentially setting up a loop, aka Snork.

The WINS server in Microsoft Windows NT 4.0 before SP4 allows remote attackers to cause a denial of service (process termination) via invalid UDP frames to port 137 (NETBIOS Name Service), as demonstrated via a flood of random packets.

NT users can gain debug-level access on a system process using the Sechole exploit.

In IIS, remote attackers can obtain source code for ASP files by appending "::$DATA" to the URL.

Windows NT 3.51 and 4.0 running WINS (Windows Internet Name Service) allows remote attackers to cause a denial of service (resource exhaustion) via a flood of malformed packets, which causes the server to slow down and fill the event logs with error messages.

Windows NT 4.0 allows remote attackers to cause a denial of service via a malformed SMB logon request in which the actual data size does not match the specified size.
