After Zero-Day Attacks, MOVEit Turns to Security Service Packs

Facing ransomware zero-days, Progress Software will release regular service packs to help customers mitigate critical security flaws.

MOVEit hack impact

Faced with a barrage of ransomware attacks hitting zero-days in its MOVEit product line, Progress Software late Thursday announced plans to release regular service packs promising a “predictable, simple and transparent process for product and security fixes.”

Less than a month after the notorious Cl0p ransomware gang started naming organizations hit by MOVEit zero-day exploits, Progress Software rolled out its first service pack with patches for at least three critical security defects that expose customer database content to malicious attackers.

“We have heard from you that a regular cadence and predictable timeline will enable you to better plan your resources and make it easier to adopt new product updates and fixes. As a part of these Service Packs, we will also be optimizing the installation process to make the upgrade process simpler,” Progress said in a note posted with the first service pack.

Software vendors typically use a service pack to deliver a collection of updates, fixes, features or enhancements to an application.  Service packs are delivered in the form of a single installable package.

Progress Software said the service packs would apply to its MOVEit products, including MOVEit Transfer and MOVEit Automation.

The initial service pack provides cover for CVE-2023-36934, a critical-severity bug in the Progress MOVEit Transfer tool.  The company described it as a SQL injection vulnerability that allows an unauthenticated attacker to gain unauthorized access to the MOVEit Transfer database. 

“An attacker could submit a crafted payload to a MOVEit Transfer application endpoint which could result in modification and disclosure of MOVEit database content,” the company said of the most serious bug.

The service pack also includes patches for CVE-2023-36932, which covers multiple high-severity Progress MOVEit Transfer vulnerabilities that allow authenticated attackers to gain unauthorized access to the MOVEit Transfer database. “An attacker could submit a crafted payload to a MOVEit Transfer application endpoint which could result in modification and disclosure of MOVEit database content,” Progress said.

Progress Software also included a fix for CVE-2023-36933, a high-severity bug that allows an attacker to invoke a method which results in an unhandled exception.  “Triggering this workflow can cause the MOVEit Transfer application to terminate unexpectedly.”
