Absolute path directory traversal vulnerability in (a) MERAK Mail Server for Windows 8.3.8r with before IceWarp Web Mail 5.6.1 and (b) VisNetic MailServer before 8.5.0.5 allows remote attackers to include arbitrary files via a full Windows path and drive letter in the (1) language parameter in accounts/inc/include.php and (2) lang_settings parameter in admin/inc/include.php, which is not properly sanitized by the securepath function, a related issue to CVE-2005-4556.

Absolute path directory traversal vulnerability in (1) MERAK Mail Server for Windows 8.3.8r with before IceWarp Web Mail 5.6.1 and (2) VisNetic MailServer before 8.5.0.5 allows remote authenticated users to include arbitrary files via a modified language parameter and a full Windows or UNC pathname in the lang_settings parameter to mail/index.html, which is not properly sanitized by the validatefolder PHP function, possibly due to an incomplete fix for CVE-2005-4558.

mail/include.html in IceWarp Web Mail 5.5.1, as used by Merak Mail Server 8.3.0r and VisNetic Mail Server version 8.3.0 build 1, does not properly initialize the default_layout and layout_settings variables when an unrecognized HTTP_USER_AGENT string is provided, which allows remote attackers to access arbitrary files via a request with an unrecognized User Agent that also specifies the desired default_layout and layout_settings parameters.

IceWarp Web Mail 5.5.1, as used by Merak Mail Server 8.3.0r and VisNetic Mail Server version 8.3.0 build 1, does not properly restrict acceptable values for the language parameter to mail/settings.html before it is stored in a database, which can allow remote authenticated users to include arbitrary PHP code via a URL in a modified lang_settings parameter to mail/index.html.

dir/include.html in IceWarp Web Mail 5.5.1, as used by Merak Mail Server 8.3.0r and VisNetic Mail Server version 8.3.0 build 1, allows remote attackers to include arbitrary local files via a null byte (%00) in the lang parameter, possibly due to a directory traversal vulnerability.

PHP remote file include vulnerability in IceWarp Web Mail 5.5.1, as used by Merak Mail Server 8.3.0r and VisNetic Mail Server version 8.3.0 build 1, when register_globals is enabled, allows remote attackers to include arbitrary local and remote PHP files via a URL in the (1) lang_settings and (2) language parameters in (a) accounts/inc/include.php and (b) admin/inc/include.php.

VisNetic WebSite 3.5 allows remote attackers to obtain the full pathname of the server via a request containing a folder that does not exist, which leaks the pathname in an error message, as demonstrated using _vti_bin/fpcount.exe.

WebSite Pro 3.1.11.0 on Windows allows remote attackers to read script source code for files with extensions greater than 3 characters via a URL request that uses the equivalent 8.3 file name.

Directory traversal vulnerability in (1) Deerfield D2Gfx 1.0.2 or (2) BadBlue Enterprise Edition 1.5.x and BadBlue Personal Edition 1.5.6 allows remote attackers to read arbitrary files via a ../ (dot dot slash) in the script used to read Microsoft Office documents.

Cross-site scripting (XSS) vulnerability in VisNetic Website before 3.5.15 allows remote attackers to inject arbitrary web script or HTML via the HTTP referer header (HTTP_REFERER) to a non-existent page, which is injected into the resulting 404 error page.
