CRITICAL:
Less critical

IMPACT:
Security Bypass, Exposure of system information, Exposure of
sensitive information

WHERE:
>From remote

SOFTWARE:
ArGoSoft Mail Server 1.8.x
http://secunia.com/product/444/

DESCRIPTION:
NSA Group has discovered some vulnerabilities in ArGoSoft Mail Server
Pro, which can be exploited by malicious users to gain knowledge of
sensitive information or bypass certain security restrictions and by
malicious people to gain knowledge of various system information. 

1) Input passed to the "UIDL" parameter in viewheaders is not
properly sanitised, which can be exploited to disclose the contents
of arbitrary files on the system via directory traversal attacks.

Example:
http://[host]/viewheaders?Folder=inbox&UIDL=../../../../../../[file]%00/

Successful exploitation requires a valid user account and access to
the webmail functionality.

2) The IMAP service does not properly sanitise input passed to the
"RENAME" command. This can be exploited to move folders to arbitrary
directories on the system.

Successful exploitation requires a valid user account and access to
the IMAP service.

3) The POP3 service supports the command "_DUMP" (can be used
pre-authentication), which dumps various information about the
system, mail server registration information, and the configuration
of the mail server.

The vulnerabilities have been confirmed in version 1.8.8.5. Other
versions may also be affected.

SOLUTION:
Restrict access to the webmail functionality and the POP3 and IMAP
services.
