Advisory Title: Cross-Site Scripting (XSS) in Neoteris IVE Allows Session Hijacking
Release Date: May 13, 2003
Product: Neoteris Instant Virtual Extranet (IVE), Versions 3.01 and Prior
Overall Risk: Medium
CVE Candidate: CAN-2003-0217
------------------------------------------------------------------------
---------------------------
PRODUCT OVERVIEW:
Neoteris Instant Virtual Extranet (IVE) is an appliance-based remote access solution that is
accessed via a standard web browser. The Neoteris IVE is one of the more well known "clientless
VPN" solutions, and in fact boasts an impressive, growing list of customers (see
http://www.neoteris.com for more information). Once authenticated to the remote network via the
IVE, a user can theoretically access all internal resources, provided the Neoteris box is
configured accordingly.
Quoting from the company website, "The Neoteris IVE has always provided a means to remote access
with a dramatically lower Total Cost of Ownership vs. traditional methods like VPN or dial. The
IVE also enhances security, by eliminating open-ended, network layer connections. The security of
the IVE has been verified by a several well-known independent security authorities."
VULNERABILITY:
A cross-site scripting (XSS) vulnerability exists in Neoteris IVE v3.01 and prior. An argument
passed to a CGI script does not properly validate input. It has been confirmed that exploiting
this vulnerability can lead to a legitimate user's session being hijacked, bypassing any
authentication.
SOLUTION:
I would like to thank Neoteris for their cooperation in developing a remediation for this
vulnerability. A patch has been released for v3.01 and prior. In addition, this issue has been
fixed in v3.1. Patch and new version release information is available for customers at
https://support.neoteris.com.
The Common Vulnerabilities and Exposures (CVE) project has assigned the name CAN-2003-0217 to this
issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org), which
standardizes names for security problems.
Special thanks to DW (shall I say greetz?) for his invaluable help with these issues.
