Description:
Tan Chew Keong has reported some vulnerabilities in Neon WebMail for Java, which can be exploited by malicious users to manipulate and disclose sensitive information, and conduct script insertion and SQL injection attacks, and by malicious people to compromise a vulnerable system.
1) An error caused due to e-mail attachments being stored insecurely inside the web root in a predictable location can be exploited to execute arbitrary JSP code via a malicious JSP file attachment.
Successful exploitation requires a valid user account or that a user is tricked into opening a malicious e-mail.
2) An error in the "updatemail" servlet where the user ID is not properly verified can be exploited by an authenticated user to move other users' e-mails.
Example:
http://[host]/updatemail?ID=[userID]&getpost=get&folderid=-1&tofolderid=-9&status=1&execute=move
3) Input passed to the "adr_sortkey" and "adr_sortkey_desc" parameters in "addrlist", and the "sortkey" and "sortkey_desc" parameters in "maillist" isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation requires that the user has been authenticated.
4) An error in the "updateuser" servlet where the "in_id" parameter is not properly verified can be exploited by an authenticated user to modify other users' Personal Profile settings (e.g. change the administrator's password)
5) Input passed to the "savefolder" and "savefilename" parameters in "downloadfile" isn't properly sanitised before being used to download e-mail attachments. This can be exploited by an authenticated user to disclose the content of arbitrary files via directory traversal attacks.
6) Input passed to the "in_name" parameter when configuring the user's name in the Personal Profile settings isn't properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in an administrator's browser session in context of an affected site when the malicious user data is viewed when listing users.
Successful exploitation requires that the user has been authenticated.
The vulnerabilities have been reported in versions 5.06 and 5.07 (build.200607050). Prior versions may also be affected.
Solution:
Update to version 5.08.
