The Microsoft Windows XP HCP URI handler has been reported prone to a vulnerability that may provide for arbitrary command execution. The issue is reported to present itself when a specially formatted HCP URI that references a local resource is processed. A remote attacker may exploit this issue to have arbitrary commands executed in the context of the user who followed the link.
This issue has been reported to be present in Polish versions of Windows XP SP1; other versions may also be vulnerable.
