BERLIN, July 22 (Reuters) - Germany's federal office for

information security (BSI) is aware of about 200 SharePoint

cases in Germany vulnerable to a security flaw, the office told

Reuters on Tuesday.

A security patch released by Microsoft MSFT.O last month

failed to fully fix a critical flaw in the U.S. tech giant's

SharePoint server software that had been identified in May,

opening the door to a sweeping global cyber espionage operation.

BSI found vulnerable SharePoint instances within the German

administration but did not detect any successful compromise on

them, it said.
