A pair of Vanishing Cabinets will act as a passage between two places. Objects placed in one cabinet will appear in the other.
The cabinets seem to ward off all known defensive spells, as they were successfully used to transport several Death Eaters from Borgin and Burkes into Hogwarts School, and Graham Montague was able to apparate into Hogwarts despite the protection spells of the school normally preventing such an action.
If one cabinet is broken, a transferred object is trapped in a kind of limbo; repairing it seems to be a very difficult task, as Draco Malfoy spent an entire school year with instructions from Borgin to accomplish, otherwise a simple Mending Charm would have been sufficient. The incantation used for the repair process is Harmonia Nectere Passus, which would require tremendous and repeated efforts, as Draco demonstrated throughout a year.
During the First Wizarding War, numerous witches and wizards used Vanishing Cabinets to anonymously disappear should the Death Eaters come to visit. Arthur Weasley mentioned this fact during Christmas of 1996 while talking to members of the Order of the Phoenix.
In 1996, Fred and George Weasley shoved Graham Montague headfirst into the broken cabinet on the first floor of Hogwarts when he tried to take points away from them. Montague eventually escaped (by Apparating) and was found in a toilet's u-bend by Draco Malfoy, who summoned Professor Snape for help. Montague revealed the previously unknown powers of the Cabinets to Draco.
The Hogwarts Vanishing Cabinet was later moved to the Room of Requirement and in 1997, Draco Malfoy successfully repaired it to allow a group of Death Eaters, including Fenrir Greyback, to enter Hogwarts from the Borgin and Burkes Vanishing Cabinet, in order to accomplish his plot to assassinate Albus Dumbledore.
