Alt-N WebAdmin 3.2.3 and 3.2.4 running with MDaemon 9.0.5, and possibly earlier, allow remote authenticated domain administrators to change a global administrator's password and gain privileges via the userlist.wdm file.

Multiple directory traversal vulnerabilities in Alt-N WebAdmin 3.2.3 and 3.2.4 running with MDaemon 9.0.5, and possibly earlier, allow remote authenticated global administrators to read arbitrary files via a .. (dot dot) in the file parameter to (1) logfile_view.wdm and (2) configfile_view.wdm.

Buffer overflow in Alt-N MDaemon, possibly 9.0.1 and earlier, allows remote attackers to execute arbitrary code via a long A0001 argument that begins with a '"' (double quote).

Format string vulnerability in the IMAP4rev1 server in Alt-N MDaemon 8.1.1 and possibly 8.1.4 allows remote attackers to cause a denial of service (CPU consumption) by creating and then listing folders whose names contain format string specifiers.

WorldClient.dll in Alt-N MDaemon and WorldClient 8.1.3 trusts a Session parameter that contains a randomly generated session ID that is associated with a username, which allows remote attackers to perform actions as other users by guessing or sniffing the random value.

WorldClient webmail in Alt-N MDaemon 8.1.3 allows remote attackers to prevent arbitrary users from accessing their inboxes via script tags in the Subject header of an e-mail message, which prevents the user from being able to access the Inbox folder, possibly due to a cross-site scripting (XSS) vulnerability.

useredit_account.wdm in Alt-N WebAdmin 3.0.4 does not properly validate account edits by the logged in user, which allows remote authenticated users to edit other users' account information via a modified user parameter.

Direct remote injection vulnerability in modalfram.wdm in Alt-N WebAdmin 3.0.4 allows remote attackers to load external webpages that appear to come from the WebAdmin server, which allows remote attackers to inject arbitrary HTML or web script to facilitate cross-site scripting (XSS) and phishing attacks.

Cross-site scripting (XSS) vulnerability in useredit_account.wdm in Alt-N WebAdmin 3.0.4 allows remote attackers to inject arbitrary web script or HTML via the user parameter.

The GUI in Alt-N Technologies MDaemon 7.2 and earlier, including 6.8, executes child processes such as NOTEPAD.EXE with SYSTEM privileges when users create new files, which allows local users with physical access to gain privileges.
