MOVEit Transfer: Improper Authentication
CVE-2024-6576 is a critical-severity improper authentication vulnerability in MOVEit Transfer from Progress Software, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 2023.0.12, 2023.1.7, 2024.0.3 as the first without the flaw, so updating MOVEit Transfer to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.62% chance of exploitation within 30 days, higher than 50% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update MOVEit Transfer to 2023.0.12 or 2023.1.7 or 2024.0.3, whichever matches your release line, or a later version.
- Read the advisory on community.progress.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
