Title: Ipswitch IMail Server Path Disclosure Vulnerability

Severity: MODERATE

Description:

Ipswitch IMail is an email server that serves clients their mail via a web interface. IMail supports most common email protocols such as SMTP, POP3, IMAP4, and LDAP, etc.

A vulnerability exists which may remotely disclose sensitive information about the host running IMail Server. When attachments are sent out via e-mail, the message header generated by IMail includes the full physical path of the attachment.

This is an example message header originating from a host running IMail:

From: "XXXXXXXXXXXXXXXX" <XXXXXXXX@XXXXXXXXX>
Reply-To: <XXXXXXXX@XXXXXXXX>
X-Sender: <XXXXXX@XXXXXXXXX>
To: <XXXXXX@XXXXXXXXX>
Subject: Slides
X-Mailer: <IMail v7.04>
X-Attachments: f:\Imail\spool\web\file.zip;
X-Sanitizer: In
MIME-Version: 1.0
Content-Type: multipart/mixed; charset="iso-8859-1"
Content-Transfer-Encoding: 8bit

The disclosed information may be used to maliciously map out the directory structure of the host, facilitating further "intelligent" attacks on the host.

Affected Products:

  • Ipswitch IMail 7.0.4
