In a recent security bulletin released by HP, the company acknowledged that its ProCurve 5400 zi switches contained virus-infected compact flash cards. As reported by CRN, the virus-laden CF cards were shipped with ProCurve switches sold after April 30, 2011.
While the tainted cards do no harm to switches themselves, the cards can infect PCs if reused. HP plans to exchange the affected switches for free.
Mike Lennon of SecurityWeek points out that HP has yet to respond on what type of virus the cards were stricken with, when discovered or place of origin.
