   Advisory ID: SYMSA-2006-010
Advisory Title: Directory Traversal in IronWebMail
        Author: Derek Callaway
  Release Date: 16-10-2006
   Application: IronWebMail(tm)
      Platform: IronMail appliance, FreeBSD 4.10 / IA-32
      Severity: Remotely exploitable/ database credential retrieval
 Vendor status: Verified by vendor. Resolved in IronMail 6.1.1 HotFix-17
    CVE Number: CVE-2006-5210


IronMail is an Internet e-mail security appliance marketed by
CipherTrust, Inc. a company specializing in messaging security.
IronMail's features include anti-spam mechanisms, zero day anti-virus
protection, intrusion prevention techniques, and a Secure WebMail
component. Secure WebMail implements Single Sign-On and integrates
RSA SecurID; it operates in conjunction with the IronWebMail HTTPS


The web server under IronWebMail employes a simple macro language
for evaluating pathname references. A loss of confidentiality occurs
as a result of faulty pathname evaluation, causing unauthenticated
access violation.

After a connection to TCP port 443 has been accepted and an SSL
session has been negotiated, a specially crafted HTTP GET request is
sent. An exploit request contains the IM_FILE identifier that can be
gleaned from the HTML source of the main IronWebMail login page:

[Current Working Directory Data Received From Web Server..]

A request for the current working directory was made using custom
IronWebMail server pathname syntax. The returned response payload
is the byte-wise representation of the web root directory. This is
the base case; other directories can be viewed as well as file
contents. For example:

GET /IM_FILE(%252e%252e/%252e%252e/%252e%252e) HTTP/1.0[CRLF][CRLF]
[Directory Data for Great-Grandparent of CWD..]

This request will display the contents of the ufs directory three-levels
up from the current working directory of the web server process.
Although literal pathnames can be provided, doubly encoding the file
location with URI ASCII escaping allows for deeper directory traversals.

This technique can be used to retrieve any file or directory accessible
by the web server process. An attacker with novice programming skills
is capable of writing a script to automate remote file system
reconnaissance by taking advantage of this issue.
