TITLE:
ArGoSoft Mail Server Three Vulnerabilities

SECUNIA ADVISORY ID:
SA14221

VERIFY ADVISORY:
http://secunia.com/advisories/14221/

CRITICAL:
Less critical

IMPACT:
Manipulation of data, Exposure of sensitive information, DoS

WHERE:
>From remote

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

DESCRIPTION:
Dr_insane has discovered three vulnerabilities in ArGoSoft Mail
Server, which can be exploited by malicious people to cause a DoS
(Denial of Service), disclose sensitive information, and create
arbitrary directories on a vulnerable system.

1) Input passed to the username in "addnewuser" isn't properly
sanitised before being used to create directories. This can be
exploited to create a directory in an arbitrary location via
directory traversal attacks.

2) An error in the handling of long passwords (about 800 bytes) in
"addnewuser" can be exploited to cause a vulnerable service to
consume a large amount of CPU resources.

3) The problem is that the script "viewlogs.pl" can be accessed
without any authentication. This can be exploited to disclose some
potentially sensitive logging information.

The vulnerabilities have been confirmed in version 1.8.7.4. Other
versions may also be affected.

SOLUTION:
Disable "Allow Creation of Accounts from Web" in Tools --> Options
--> General.

Restrict access to the "viewlogs.pl" script.
