Microsoft warns: Hackers are actively exploiting a zero day vulnerability in Internet Explorer, prompting a warning from the Department of Homeland Security (DHS) Cybersecurity & Infrastructure Security Agency (CISA).
“Microsoft is aware of limited targeted attacks” in a remote code execution (RCE) vulnerability [CVE-2020-0674] in the scripting engine of Internet Explorer across all versions of Windows that would let a hacker obtain the same rights as a current user, Microsoft warned Friday.
“If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system,” the company said.
Attackers could then do things like install programs, manipulate data or even create new accounts to which they’d have full user rights. “In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website, for example, by sending an email,” Microsoft explained.

CISA’s warning came on the heels of Microsoft’s advisory. The agency recommended “users and administrators to review Microsoft’s Advisory ADV20001 and CERT/CC’s Vulnerability Note VU#338824 for more information, implement workarounds, and apply updates when available” and urged them to “consider using Microsoft Edge or an alternate browser until patches are made available.”
