Description:
Dr_insane has reported some vulnerabilities in Mercur Messaging, which can be exploited by malicious people to manipulate files and disclose sensitive information.
1) It is possible to disclose the source of ".ctml" files by appending a white space ("%20") in the request.
2) Input passed to the "Folder.Id" parameter in "deletefolder.ctml", "deletemessage.ctml", "origmessage.ctml" and "readmessage.ctml", the "Message.Id" parameter in "editmessage.ctml" and the "Message.Command" parameter in "messages.ctml" isn't properly sanitised before being used. This can be exploited to read, delete, move or create arbitrary files via directory traversal attacks.
Successful exploitation requires user to be authenticated to the web mail service.
The vulnerabilities have been reported in version 2005 SP2 (file version 5.0.10.0). Other versions may also be affected.
Solution:
Grant only trusted users access to the web mail. Also filter malicious characters and character sequences in a proxy server or firewall with URL filtering capabilities.
