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) langsettings 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 langsettings 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.

Cross-site scripting (XSS) vulnerability in index.html in IceWarp WebMail 5.5.1 and earlier allows remote attackers to inject arbitrary web script or HTML via the PHPSESSID parameter.

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 langsettings 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.

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 defaultlayout and layoutsettings variables when an unrecognized HTTPUSERAGENT string is provided, which allows remote attackers to access arbitrary files via a request with an unrecognized User Agent that also specifies the desired defaultlayout and layoutsettings parameters.

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 registerglobals is enabled, allows remote attackers to include arbitrary local and remote PHP files via a URL in the (1) langsettings and (2) language parameters in (a) accounts/inc/include.php and (b) admin/inc/include.php.

Multiple directory traversal vulnerabilities in MERAK Mail Server 8.2.4r with Icewarp Web Mail 5.5.1, and possibly earlier versions, allows remote attackers to (1) delete arbitrary files or directories via a relative path to the id parameter to logout.html or (2) include arbitrary PHP files or other files via the helpid parameter to help.html.

MERAK Mail Server 8.2.4r with Icewarp Web Mail 5.5.1, and possibly earlier versions, allows remote attackers to obtain sensitive information via a direct request to bwlistinc.html, which reveals the path in an error message.

Multiple cross-site scripting (XSS) vulnerabilities in MERAK Mail Server 8.2.4r with Icewarp Web Mail 5.5.1, and possibly earlier versions, allow remote attackers to inject arbitrary web script or HTML via the (1) id parameter to blank.html, or the createdataCX parameter to (2) calendard.html, (3) calendarm.html, or (4) calendarw.html.

Merak Mail Server 8.0.3 with Icewarp Web Mail 5.4.2, when the mailbox.dat file does not exist, allows remote authenticated users to determine if a file exists via the folder parameter to attachment.html.

Multiple cross-site scripting (XSS) vulnerabilities in Merak Mail Server 8.0.3 with Icewarp Web Mail 5.4.2 allow remote authenticated users to inject arbitrary web script or HTML via (1) the E-mail address, Note, or Public Certificate fields to address.html, (2) addressaction.html, (3) the Signature field to settings.html, or (4) the Shared calendars to calendarsettings.html.

Unknown vulnerability in Merak Mail Server 8.0.3 with Icewarp Web Mail 5.4.2 allows remote authenticated users to obtain the full path of the server via certain requests to (1) calendaraddevent.html, (2) calendarevent.html, or (3) calendartask.html.

Merak Mail Server 8.0.3 with Icewarp Web Mail 5.4.2 allows remote authenticated users to (1) move their home directory via viewaction.html or (2) move arbitrary files via the importfile parameter to importaction.html.

MERAK Mail Server 7.6.0 with Icewarp Web Mail 5.3.0 allows remote authenticated users to gain sensitive information via an HTTP request to (1) calendard.html, (2) calendarm.html, (3) calendarw.html, or (4) calendary.html, which reveal the installation path.

MERAK Mail Server 7.6.0 with Icewarp Web Mail 5.3.0 and Mail Server 7.6.4r with Icewarp Mail Server 5.3.2 uses weak encryption in the (1) users.cfg, (2) settings.cfg, (3) users.dat or (4) user.dat files, which allows local users to extract the passwords.

Multiple cross-site scripting vulnerabilities in MERAK Mail Server 7.6.0 with Icewarp Web Mail 5.3.0 allow remote attackers to inject arbitrary web script or HTML via the (1) username parameter to login.html, (2) accountid parameter to accountsettingsadd.html, or the (3) note, (4) title, and (5) location fields to calendar.html.

accountsettingsadd.html in Merak Mail Server 7.4.5 with Icewarp Web Mail 5.2.7 and possibly other versions allow remote attackers to create text files with arbitrary content via the accountid parameter.

attachment.html in Merak Mail Server 7.4.5 with Icewarp Web Mail 5.2.7 and possibly other versions allows remote attackers to view other users' attachments by specifying the username and message ID in an HTTP request.

Merak Mail Server 7.4.5 with Icewarp Web Mail 5.2.7 and possibly other versions allows remote attackers to gain sensitive information via a direct request to (1) accountsettingsadd.html or (2) topmenu.html.

viewaction.html in Merak Mail Server 7.4.5 with Icewarp Web Mail 5.2.7 and possibly other versions allows remote attackers to (1) delete arbitrary files via the originalfolder parameter or (2) move arbitrary files via the messageid parameter.

Multiple directory traversal vulnerabilities Merak Mail Server 7.4.5 with Icewarp Web Mail 5.2.7, and possibly other versions, allow remote attackers to (1) create arbitrary directories via a .. (dot dot) in the user parameter to viewaction.html or (2) rename arbitrary files via a ....// (doubled dot dot) in the folderold or folder parameters to folders.html.

Cross-site scripting (XSS) vulnerability in MERAK Mail Server 7.4.5 with Icewarp Web Mail 5.2.7 and possibly other versions allows remote attackers to execute arbitrary web script or HTML via the (1) User name parameter to accountsettings.html or (2) Search string parameter to search.html.

Cross-site scripting (XSS) vulnerability in IceWarp Web Mail 3.3.3 and 3.4.5 allows remote attackers to inject arbitrary web script or HTML via the "Full Name" (addressname) parameter.

Merak Mail IceWarp Web Mail uses a static identifier as a user session ID that does not change across sessions, which could allow remote attackers with access to the ID to gain privileges as that user, e.g. by extracting the ID from the user's answer or forward URLs.
