Internet Explorer File Identification Variant

Secunia Advisory: SA10820
Release Date: 2004-02-09

Critical: Not critical
Impact: Exposure of system information
Where: From remote

Software: Microsoft Internet Explorer 6

Description:
Jelmer has discovered a vulnerability in Internet Explorer, allowing
malicious sites to detect the presence of local files.

The problem is that a vbscript can cause Internet Explorer to report
different error messages depending on whether a file specified in a
form exists or not. This could be exploited to determine the presence
of specific programs or data.

This is a variant of older vulnerabilities reported to affect previous
versions of Internet Explorer.

The vulnerability has been confirmed in version 6.0 SP1 with all
patches applied.

Solution:
Disable active scripting except for trusted sites.
