MOVEit Vulnerabilities Alert | June 2023

There are several recent security issues in MOVEit file transfer software. Here's what you need to know.

Last updated:  June 16, 2023

Update: As of July 5th, 2023 several new vulnerabilities were announced. Organizations using MOVEit should immediately follow current remediation steps.


On July 5th, 2023 several new vulnerabilities were discovered in MOVEit file transfer software. Progress, the software developer, is recommending users update to the latest fixed version immediately. This is in addition to prior patches that have been applied. Given mass-exploitation currently taking place against MOVEit software, we strongly urge you to take immediate action.

This new vulnerability is in addition to the zero-day vulnerability announced on May 31, 2023 (CVE-2023-34362) that has been under attack by the ransomware group, CLOP. If you followed our prior guidance to update and look for indicators of compromise (thank you), but please note you must now address this new vulnerability.


Attackers can exploit these vulnerabilities to gain unauthorized access to vulnerable systems. There are reports of mass-exploitation including data theft attacks against a large number of vulnerable targets, and at least one threat actor group has begun posting victim data on their leak site. Corvus has observed ransomware groups exploit similar vulnerabilities in file transfer software to steal and encrypt sensitive data. It is crucial that remediation steps are followed.

Next Steps

We encourage your organization to take the following steps recommended by the manufacturer, Progress Software, to mitigate against potential attack:

  1. If you have NOT applied the May 2023 patch: Follow all the remediation steps in the following article: MOVEit Transfer Critical Vulnerability (May 2023) and then proceed to step 2.
