Unpatched Microsoft Exchange Servers Vulnerable to CVE-2020-0688

Microsoft Exchange Servers affected by a remote code execution vulnerability, known as CVE-2020-0688, continue to be an attractive target for malicious cyber actors. A remote attacker can exploit this vulnerability to take control of an affected system that is unpatched.

Although Microsoft disclosed the vulnerability and provided software patches for the various affected products in February 2020, advanced persistent threat actors are targeting unpatched servers, according to recent open-source reports. The Cybersecurity and Infrastructure Security Agency (CISA) urges users and administrators review Microsoft’s Advisory and the National Security Agency’s tweet on CVE-2020-0688 for more information and apply the necessary patches as soon as possible.
