The w3svc.dll ISAPI filter in Front Page Server Extensions and ASP.NET for Internet Information Server (IIS) 4.0, 5.0, and 5.1 does not properly handle the error condition when a long URL is provided, which allows remote attackers to cause a denial of service (crash) when the URL parser accesses a null pointer.

Buffer overflow in the ASP data transfer mechanism in Internet Information Server (IIS) 4.0, 5.0, and 5.1 allows remote attackers to cause a denial of service or execute code, aka "Microsoft-discovered variant of Chunked Encoding buffer overrun."

Buffer overflow in ASP Server-Side Include Function in IIS 4.0, 5.0 and 5.1 allows remote attackers to cause a denial of service and possibly execute arbitrary code via long file names.

GoAhead Web Server 2.1.7 and earlier allows remote attackers to obtain the source code of ASP files via a URL terminated with a /, \, %2f (encoded /), %20 (encoded space), or %00 (encoded null) character, which returns the ASP source code unparsed.

CentraOne 5.2 and Centra ASP with basic authentication enabled creates world-writable base64 encoded log files, which allows local users to obtain cleartext passwords from decoded log files and impersonate users.

Directory traversal vulnerability in AspUpload 2.1, in certain configurations, allows remote attackers to upload and read arbitrary files, and list arbitrary directories, via a .. (dot dot) in the Filename parameter in (1) UploadScript11.asp or (2) DirectoryListing.asp.

Microsoft IIS 4.0 and before, when installed on a FAT partition, allows a remote attacker to obtain source code of ASP files via a URL encoded with Unicode.

Surf-Net ASP Forum before 2.30 uses easily guessable cookies based on the UserID, which allows remote attackers to gain administrative privileges by calculating the value of the admin cookie (UserID 1), i.e. "0888888."

Directory traversal vulnerability in Sun Chili!Soft ASP on multiple Unixes allows a remote attacker to read arbitrary files above the web root via a '..' (dot dot) attack in the sample script 'codebrws.asp'.

Sun Chili!Soft ASP has weak permissions on various configuration files, which allows a local attacker to gain additional privileges and create a denial of service.

Scripting.FileSystemObject in asp.dll for Microsoft IIS 4.0 and 5.0 allows local or remote attackers to cause a denial of service (crash) via (1) creating an ASP program that uses Scripting.FileSystemObject to open a file with an MS-DOS device name, or (2) remotely injecting the device name into ASP programs that internally use Scripting.FileSystemObject.

vWebServer 1.2.0 allows remote attackers to view arbitrary ASP scripts via a request for an ASP script that ends with a URL-encoded space character (%20).

Multiple buffer overflows in s.cgi program in Aspseek search engine 1.03 and earlier allow remote attackers to execute arbitrary commands via (1) a long HTTP query string, or (2) a long tmpl parameter.

Chili!Soft ASP for Linux before 3.6 does not properly set group privileges when running in inherited mode, which could allow attackers to gain privileges via malicious scripts.

The source.asp example script in the Apache ASP module Apache::ASP 1.93 and earlier allows remote attackers to modify files.

The shtml.exe program in the FrontPage extensions package of IIS 4.0 and 5.0 allows remote attackers to determine the physical path of HTML, HTM, ASP, and SHTML files by requesting a file that does not exist, which generates an error message that reveals the path.

Microsoft Index Server allows remote attackers to view the source code of ASP files by appending a %20 to the filename in the CiWebHitsFile argument to the null.htw URL.

IIS 4.0 and 5.0 does not properly perform ISAPI extension processing if a virtual directory is mapped to a UNC share, which allows remote attackers to read the source code of ASP and other files, aka the "Virtualized UNC Share" vulnerability.

IIS allows local users to cause a denial of service via invalid regular expressions in a Visual Basic script in an ASP page.

IIS 2.0 and 3.0 allows remote attackers to read the source code for ASP pages by appending a . (dot) to the end of the URL.
