Title: Microsoft Windows autorun.inf Vulnerability

Severity: MODERATE

Description:

The Windows Autorun feature was designed to allow an executable and an icon to be specified for any piece of removable media. Upon insertion, the icon would be displayed for the drive, and the executable would automatically run. This feature also applies to fixed and networked drives however, making it much easier to abuse. Any user with write access to the root of a logical drive can install an executable and specify it in an autorun.inf file. Anytime that drive is accessed later, the code will run with the privileges of the currently logged in user. This could be used in privilege escalation attacks.

Affected Products:

  • Microsoft Windows 95
  • Microsoft Windows 98
  • Microsoft Windows NT 4.0
  • Microsoft Windows NT Enterprise Server 4.0
  • Microsoft Windows NT Server 4.0
  • Microsoft Windows NT Terminal Server 4.0
