firefox-geckoactivexobject-info-disclosure (54798) The risk level is classified as LowLow Risk

Description:

Mozilla Firefox and SeaMonkey could allow a remote attacker to obtain sensitive information. Different exception error messages are returned by GeckoActiveXObject based on the existance of the ProjID in the system registry for the requested COM object. A remote attacker could exploit this vulnerability to enumerate a victim's existing COM objects and possibly allow the attacker to create a profile to track the victim's browser sessions.
