-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Symantec Vulnerability Research http://www.symantec.com/research Security Advisory 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 Reference: http://www.securityfocus.com/bid/20436 Overview: 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 server. Details: 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: GET /IM_FILE(.) HTTP/1.0[CRLF][CRLF] [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.
