Microsoft Windows

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.

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 "AEDebug" registry key is installed with insecure permissions, which allows local users to modify the key to specify a Trojan Horse debugger which is automatically executed on a system crash.

Buffer overflow in Remote Access Service (RAS) client allows an attacker to execute commands or cause a denial of service via a malformed phonebook entry.

Buffer overflow in Windows NT 4.0 help file utility via a malformed help file.

The system root folder of Microsoft Windows 2000 has default permissions of Everyone group with Full access (Everyone:F) and is in the search path when locating programs during login or application launch from the desktop, which could allow attackers to gain privileges as other users via Trojan horse programs.

The Windows help system can allow a local user to execute commands as another user by editing a table of contents metafile with a .CNT extension and modifying the topic action to include the commands to be executed when the .hlp file is accessed.

Local users in Windows NT can obtain administrator privileges by changing the KnownDLLs list to reference malicious programs.

Buffer overflow in Windows Kernel allows local users to gain privileges by causing certain error messages to be passed to a debugger.

The PATH in Windows NT includes the current working directory (.), which could allow local users to gain privileges by placing Trojan horse programs with the same name as commonly used system programs into certain directories.

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.

Windows NT 4.0 SP4 and earlier allows local users to gain privileges by modifying the symbolic link table in the \?? object folder using a different case letter (upper or lower) to point to a different device.

The Windows NT guest account is enabled.

The Windows NT scheduler uses the drive mapping of the interactive user who is currently logged onto the system, which allows the local user to gain privileges by providing a Trojan horse batch file in place of the original batch file.

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

A Windows NT user has inappropriate rights or privileges, e.g. Act as System, Add Workstation, Backup, Change System Time, Create Pagefile, Create Permanent Object, Create Token Name, Debug, Generate Security Audit, Increase Priority, Increase Quota, Load Driver, Lock Memory, Profile Single Process, Remote Shutdown, Replace Process Token, Restore, System Environment, Take Ownership, or Unsolicited Input.

When an administrator in Windows NT or Windows 2000 changes a user policy, the policy is not properly updated if the local ntconfig.pol is not writable by the user, which could allow local users to bypass restrictions that would otherwise be enforced by the policy, possibly by changing the policy file to be read-only.

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 user can use SUBST to map a drive letter to a folder, which is not unmapped after the user logs off, potentially allowing that user to modify the location of folders accessed by later users.

Mathcad 12 through 13.1 allows local users to bypass the security features by directly accessing or editing the XML representation of the worksheet with a text editor or other program, which allows attackers to (1) bypass password protection by replacing the password field with a hash of a known password, (2) modify timestamps to avoid detection of modifications, (3) remove locks by removing the "is-locked" attribute, and (4) view locked data, which is stored in plaintext.

Cross-site scripting (XSS) vulnerability in the default ASP pages on Microsoft Site Server 3.0 on Windows NT 4.0 allows remote attackers to inject arbitrary web script or HTML via the (1) ctr parameter in Default.asp and (2) the query string to formslogin.asp.

Multiple cross-site scripting (XSS) vulnerabilities (1) in the WYSIWYG editors, (2) during local group creation, (3) during HTML redirects, (4) in the HTML import, (5) in the Rich text editor, and (6) in link-page in IBM Lotus Quickr 8.1 services for Lotus Domino before Hotfix 15 allow remote attackers to inject arbitrary web script or HTML via unknown vectors, including (7) the Imported Page. NOTE: the vulnerability in the WYSIWYG editors may exist because of an incomplete fix for CVE-2008-2163.

Cross-site scripting (XSS) vulnerability in IBM Lotus Quickr 8.1 before Hotfix 5 for Windows and AIX, and before Hotfix 3 for i5/OS, allows remote attackers to inject arbitrary web script or HTML via unknown vectors related to "WYSIWYG editors."

The Recycle Bin utility in Windows NT and Windows 2000 allows local users to read or modify files by creating a subdirectory with the victim's SID in the recycler directory, aka the "Recycle Bin Creation" vulnerability.

NT Virtual DOS Machine (NTVDM.EXE) in Windows 2000, NT and XP does not verify user execution permissions for 16-bit executable files, which allows local users to bypass the loader and execute arbitrary programs.

The DCOM RPC interface for Microsoft Windows NT 4.0, 2000, XP, and Server 2003 allows remote attackers to cause network communications via an "alter context" call that contains additional data, aka the "Object Identity Vulnerability."

A remote attacker can disable the virus warning mechanism in Microsoft Excel 97.

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.

GINA in Windows NT 4.0 allows attackers with physical access to display a portion of the clipboard of the user who has locked the workstation by pasting (CTRL-V) the contents into the username prompt.

The installer for BackOffice Server includes account names and passwords in a setup file (reboot.ini) which is not deleted.

Buffer overflow in the SHGetPathFromIDList function of the Serv-U FTP server allows attackers to cause a denial of service by performing a LIST command on a malformed .lnk file.

Windows NT 4.0 SP 6a allows a local user with write access to winnt/system32 to cause a denial of service (crash in lsass.exe) by running the NT4ALL exploit program in 'SPECIAL' mode.

Microsoft TCP/IP Printing Services, aka Print Services for Unix, allows an attacker to cause a denial of service via a malformed TCP/IP print request.

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

A Windows NT system does not clear the system page file during shutdown, which might allow sensitive information to be recorded.

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.

The rdisk utility in Microsoft Terminal Server Edition and Windows NT 4.0 stores registry hive information in a temporary file with permissions that allow local users to read it, aka the "RDISK Registry Enumeration File" vulnerability.

Office Shortcut Bar (OSB) in Windows 3.51 enables backup and restore permissions, which are inherited by programs such as File Manager that are started from the Shortcut Bar, which could allow local users to read folders for which they do not have permission.

The screensaver on Windows NT 4.0, 2000, XP, and 2002 does not verify if a domain account has already been locked when a valid password is provided, which makes it easier for users with physical access to conduct brute force password guessing.

"Shatter" style vulnerability in the Window Management application programming interface (API) for Microsoft Windows 98, Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 allows local users to gain privileges by using certain API functions to change properties of privileged programs using the SetWindowLong and SetWIndowLongPtr API functions.
