CISA Warns of Hackers Exploiting Zerologon Vulnerability

Security Week

Dubbed Zerologon, the security flaw is tracked as CVE-2020-1472 and was patched in August 2020. Earlier this month, CISA issued an Emergency Directive that required all federal agencies to install the patches within three days.

The vulnerability allows an unauthenticated attacker connected to a domain controller using Netlogon to gain domain administrator access. The attacker would need to leverage a specially crafted application running on a device on the network to successfully exploit the bug.

Samba issued patches for the bug too, and last week Microsoft revealed that it was seeing the first attempts to target the Zerologon flaw, and CISA was quick to issue an alert on such attacks as well.
