Vulnerabilities (CVE)

Vulnerabilities in IIS 4.0 and 5.0 do not properly protect against cross-site scripting (CSS) attacks. They allow a malicious web site operator to embed scripts in a link to a trusted site, which are returned without quoting in an error message back to the client. The client then executes those scripts in the same context as the trusted site, aka the "IIS Cross-Site Scripting" vulnerabilities.

The Compressed Folders feature in Microsoft Windows 98 with Plus! Pack, Windows Me, and Windows XP does not properly check the destination folder during the decompression of ZIP files, which allows attackers to place an executable file in a known location on a user's system, aka "Incorrect Target Path for Zipped File Decompression."

Microsoft HTML control as used in (1) Internet Explorer 5.0, (2) FrontPage Express, (3) Outlook Express 5, and (4) Eudora, and possibly others, allows remote malicious web site or HTML emails to cause a denial of service (100% CPU consumption) via large HTML form fields such as text inputs in a table cell.

Buffer overflow in the ism.dll ISAPI extension that implements HTR scripting in Internet Information Server (IIS) 4.0 and 5.0 allows attackers to cause a denial of service or execute arbitrary code via HTR requests with long variable names.

A handler routine for the Network Connection Manager (NCM) in Windows 2000 allows local users to gain privileges via a complex attack that causes the handler to run in the LocalSystem context with user-specified code.

Microsoft Word 2002 and earlier allows attackers to automatically execute macros without warning the user by embedding the macros in a manner that escapes detection by the security scanner.

Access violation in LSASS.EXE (LSA/LSARPC) program in Windows NT allows a denial of service.

Unspecified vulnerability in Microsoft Hyperlink Object Library (hlink.dll), possibly a buffer overflow, allows user-assisted attackers to execute arbitrary code via crafted hyperlinks that are not properly handled when hlink.dll "uses a file containing a malformed function," aka "Hyperlink Object Function Vulnerability."

Microsoft Internet Explorer 6 on Windows XP SP2 allows remote attackers to cause a denial of service (crash) by iterating over any native function, as demonstrated with the window.alert function, which triggers a null dereference.

Outlook Web Access (OWA) in Microsoft Exchange 5.5 Server, when used with Internet Explorer, does not properly detect certain inline script, which can allow remote attackers to perform arbitrary actions on a user's Exchange mailbox via an HTML e-mail message.

Multiple integer overflows in Microsoft ASN.1 library (MSASN1.DLL), as used in LSASS.EXE, CRYPT32.DLL, and other Microsoft executables and libraries on Windows NT 4.0, 2000, and XP, allow remote attackers to execute arbitrary code via ASN.1 BER encodings with (1) very large length fields that cause arbitrary heap data to be overwritten, or (2) modified bit strings.

Buffer overflow in Internet Explorer 4.01 and earlier allows remote attackers to execute arbitrary commands via a long URL with the "mk:" protocol, aka the "MK Overrun security issue."

Cross-site scripting vulnerability in Internet Explorer 6.0 allows remote attackers to execute scripts in the Local Computer zone via a URL that exploits a local HTML resource file, aka the "Cross-Site Scripting in Local HTML Resource" vulnerability.

Windows Media Player ActiveX object as used in Internet Explorer 5.0 returns a specific error code when a file does not exist, which allows remote malicious web sites to determine the existence of files on the client.

The terminal services screensaver for Microsoft Windows 2000 does not automatically lock the terminal window if the window is minimized, which could allow local users to gain access to the terminal server window.

The registry in Windows NT can be accessed remotely by users who are not administrators.

Argument injection vulnerability in the URI handler in Skype 2.0.*.104 and 2.5.*.0 through 2.5.*.78 for Windows allows remote authorized attackers to download arbitrary files via a URL that contains certain command-line switches.

HyperTerminal application for Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 does not properly validate the length of a value that is saved in a session file, which allows remote attackers to execute arbitrary code via a malicious HyperTerminal session file (.ht), web site, or Telnet URL contained in an e-mail message, triggering a buffer overflow.

Microsoft Internet Explorer 5.0.1 through 6.0 allows remote attackers to determine the existence of arbitrary files via the VBScript LoadPicture method, which returns an error code if the file does not exist.

CHKDSK in Microsoft Windows 2000 before Update Rollup 1 for SP4, Windows XP, and Windows Server 2003, when running in fix mode, does not properly handle security descriptors if the master file table contains a large number of files or if the descriptors do not satisfy certain NTFS conventions, which could cause ACLs for some files to be reverted to less secure defaults, or cause security descriptors to be removed.

The Microsoft Active Movie ActiveX Control in Internet Explorer 5 does not restrict which file types can be downloaded, which allows an attacker to download any type of file to a user's system by encoding it within an email message or news post.

The xp_proxiedmetadata function in Microsoft SQL Server 2000 and SQL Server Desktop Engine (MSDE) does not properly restrict the length of a buffer before calling the srv_paraminfo function in the SQL Server API for Extended Stored Procedures (XP), which allows an attacker to cause a denial of service or execute arbitrary commands, aka the "Extended Stored Procedure Parameter Parsing" vulnerability.

Buffer overflow in the Windows Shell function in Microsoft Windows XP allows remote attackers to execute arbitrary code via an .MP3 or .WMA audio file with a corrupt custom attribute, aka "Unchecked Buffer in Windows Shell Could Enable System Compromise."

IIS 5.0 allows remote attackers to obtain source code for .ASP files and other scripts via an HTTP GET request with a "Translate: f" header, aka the "Specialized Header" vulnerability.

The user interface in the Windows Firewall does not properly display certain malformed entries in the Windows Registry, which makes it easier for attackers with administrator privileges to hide activities if the administrator only uses the Windows Firewall interface to monitor exceptions. NOTE: the vendor disputes this issue, saying that since administrative privileges are already required, it is not a vulnerability. CVE has not yet formally decided if such "information hiding" issues should b ...

The Store Service in Microsoft Exchange 2000 allows remote attackers to cause a denial of service (CPU consumption) via a mail message with a malformed RFC message attribute, aka "Malformed Mail Attribute can Cause Exchange 2000 to Exhaust CPU Resources."

Buffer overflow in cmd.exe in Windows NT 4.0 may allow local users to execute arbitrary code via a long pathname argument to the cd command.

The SMB signing capability in the Server Message Block (SMB) protocol in Microsoft Windows 2000 and Windows XP allows attackers to disable the digital signing settings in an SMB session to force the data to be sent unsigned, then inject data into the session without detection, e.g. by modifying group policy information sent from a domain controller.

The setup wizard (ie5setup.exe) for Internet Explorer 5.0 disables (1) the screen saver, which could leave the system open to users with physical access if a failure occurs during an unattended installation, and (2) the Task Scheduler Service, which might prevent the scheduled execution of security-critical programs.

Microsoft Internet Explorer 6.0 SP1 and possibly other versions allows remote attackers to cause a denial of service and possibly execute arbitrary code by instantiating COM objects as ActiveX controls, including (1) imskdic.dll (Microsoft IME), (2) chtskdic.dll (Microsoft IME), and (3) msoe.dll (Outlook), which leads to memory corruption. NOTE: it is not certain whether the issue is in Internet Explorer or the individual DLL files.
