Threat actors are exploiting yet-to-be-disclosed Microsoft Exchange zero-day bugs allowing for remote code execution, according to claims made by security researchers at Vietnamese cybersecurity outfit GTSC, who first spotted and reported the attacks.
The researchers reported the security vulnerabilities to Microsoft privately three weeks ago through the Zero Day Initiative, which tracks them as ZDI-CAN-18333 and ZDI-CAN-18802 after its analysts validated the issues.
"GTSC submitted the vulnerability to the Zero Day Initiative right away to work with Microsoft so that a patch could be prepared as soon as possible," they added.
Trend Micro released a security advisory Thursday evening confirming that they submitted the two new Microsoft Exchange zero-day vulnerabilities discovered by GTSC to Microsoft.
There's reports emerging that a new zero day exists in Microsoft Exchange, and is being actively exploited in the wild.
"We recommend all organizations/enterprises around the world that are using Microsoft Exchange Server to check, review, and apply the above temporary remedy as soon as possible to avoid potential serious damages," GTSC added.
