Title: Microsoft Outlook Arbitrary Code Execution Vulnerability

Severity: CRITICAL

Description:

Microsoft Outlook introduces a vulnerability that may allow attackers to execute arbitrary commands.

Outlook introduces an ActiveX control called "Microsoft Outlook View Control". The flaw is that this control is marked 'safe for scripting' when it should not be. It is therefore accessible to scripts embedded in html documents, including email and remote websites.

Scripts can execute commands through a property of this control called 'application'.

It may be possible for remote attacker to gain access to client systems if victims view maliciously created websites or open hostile email messages.

Affected Products:

  • Microsoft Office XP
  • Microsoft Outlook 2000 0.0.0
  • Microsoft Outlook 2002 0.0.0
  • Microsoft Outlook 98 0.0.0
