Hewlett Packard acknowledged a security issue with storage area networking equipment after reports surfaced about a hard-coded back door account. The company was responding to published reports about the existence of a hard coded user name and password that could provide unknown assailants with administrative access to HP StorageWorks P2000 product. HP said the flaw, which it did not describe, does not affect its MSA line of storage solutions, as initially reported. The Stuxnet worm allegedly took advantage of a long known back door account in the WinCC industrial control software manufactured by Siemens.
