| 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.
