Vulnerabilidades

Windows 2000 and Windows NT allows local users to cause a denial of service (reboot) by executing a command at the command prompt and pressing the F7 and enter keys several times while the command is executing, possibly related to an exception handling error in csrss.exe.

Information disclosure vulnerability in Microsoft Windows 2000 telnet service allows remote attackers to determine the existence of user accounts such as Guest, or log in to the server without specifying the domain name, via a malformed userid.

Handle leak in Microsoft Windows 2000 telnet service allows attackers to cause a denial of service by starting a large number of sessions and terminating them.

Microsoft Windows 2000 telnet service allows attackers to prevent idle Telnet sessions from timing out, causing a denial of service by creating a large number of idle sessions.

Windows 2000 domain controller in Windows 2000 Server, Advanced Server, or Datacenter Server allows remote attackers to cause a denial of service via a flood of malformed service requests.

Microsoft Windows 2000 telnet service allows a local user to make a certain system call that allows the user to terminate a Telnet session and cause a denial of service.

Buffer overflow in Microsoft Visual Studio RAD Support sub-component of FrontPage Server Extensions allows remote attackers to execute arbitrary commands via a long registration request (URL) to fp30reg.dll.

Running Windows 2000 LDAP Server over SSL, a function does not properly check the permissions of a user request when the directory principal is a domain user and the data attribute is the domain password, which allows local users to modify the login password of other users.

Microsoft Windows 2000 telnet service allows attackers to cause a denial of service (crash) via a long logon command that contains a backspace.

Microsoft Windows 2000 telnet service creates named pipes with predictable names and does not properly verify them, which allows local users to execute arbitrary commands by creating a named pipe with the predictable name and associating a malicious program with it, the second of two variants of this vulnerability.

Microsoft Windows 2000 telnet service creates named pipes with predictable names and does not properly verify them, which allows local users to execute arbitrary commands by creating a named pipe with the predictable name and associating a malicious program with it, the first of two variants of this vulnerability.

The change password option in the Windows Security interface for Windows 2000 allows attackers to use the option to attempt to change passwords of other users on other systems or identify valid accounts by monitoring error messages, possibly due to a problem in the NetuserChangePassword function.

Task Manager in Windows 2000 does not allow local users to end processes with uppercase letters named (1) winlogon.exe, (2) csrss.exe, (3) smss.exe and (4) services.exe via the Process tab which could allow local users to install Trojan horses that cannot be stopped with the Task Manager.

Multiple TCP implementations could allow remote attackers to cause a denial of service (bandwidth and CPU exhaustion) by setting the maximum segment size (MSS) to a very small number and requesting large amounts of data, which generates more packets with less TCP-level data that amplify network traffic and consume…

Microsoft Data Access Component Internet Publishing Provider 8.103.2519.0 and earlier allows remote attackers to bypass Security Zone restrictions via WebDAV requests.

Memory leak in Microsoft 2000 domain controller allows remote attackers to cause a denial of service by repeatedly connecting to the Kerberos service and then disconnecting without sending any data.

Buffer overflow in Internet Printing ISAPI extension in Windows 2000 allows remote attackers to gain root privileges via a long print request that is passed to the extension through IIS 5.0.

The default configuration of the Dr. Watson program in Windows NT and Windows 2000 generates user.dmp crash dump files with world-readable permissions, which could allow a local user to gain access to sensitive information.

Microsoft Windows 2000 Encrypted File System does not properly destroy backups of files that are encrypted, which allows a local attacker to recover the text of encrypted files.

Windows 2000 allows local users to cause a denial of service and possibly gain privileges by setting a hardware breakpoint that is handled using global debug registers, which could cause other processes to terminate due to an exception, and allow hijacking of resources such as named pipes.

Windows 98 and Windows 2000 Java clients allow remote attackers to cause a denial of service via a Java applet that opens a large number of UDP sockets, which prevents the host from establishing any additional UDP connections, and possibly causes a crash.

Buffer overflow in Windows 2000 event viewer snap-in allows attackers to execute arbitrary commands via a malformed field that is improperly handled during the detailed view of event records.

Network Dynamic Data Exchange (DDE) in Windows 2000 allows local users to gain SYSTEM privileges via a "WM_COPYDATA" message to an invisible window that is running with the privileges of the WINLOGON process.

The default permissions for the SNMP Parameters registry key in Windows NT 4.0 allows remote attackers to read and possibly modify the SNMP community strings to obtain sensitive information or modify network configuration, aka one of the "Registry Permissions" vulnerabilities.

The "Configure Your Server" tool in Microsoft 2000 domain controllers installs a blank password for the Directory Service Restore Mode, which allows attackers with physical access to the controller to install malicious programs, aka the "Directory Service Restore Mode Password" vulnerability.
