The useredit_account.wdm module in Alt-N WebAdmin 3.2.5 running with MDaemon 9.0.6, and possibly earlier versions, allows remote authenticated domain administrators to gain privileges and obtain access to the system mail queue by modifying the mailbox of the MDaemon user account to use the mailbox of another account.

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.
