'Tens of Thousands' of SharePoint Servers at Risk. Microsoft Issues No Patch


"Anybody who's got a hosted SharePoint server has got a problem," the senior VP of cybersecurity firm CrowdStrike told the Washington Post. "It's a significant vulnerability."

"We are seeing attempts to exploit thousands of SharePoint servers globally before a patch is available," said Pete Renals, a senior manager with Palo Alto Networks' Unit 42. With access to these servers, which often connect to Outlook email, Teams and other core services, a breach can lead to theft of sensitive data as well as password harvesting, Netherlands-based research company Eye Security noted. "So pushing out a patch on Monday or Tuesday doesn't help anybody who's been compromised in the past 72 hours," said one researcher, who spoke on the condition of anonymity because a federal investigation is ongoing.
