Senserva AI Opinion for CVE-2023-34362

The MOVEit Transfer SQL injection produced one of the largest mass data theft campaigns on record: an unauthenticated attacker gains access to the product's database across MySQL, Microsoft SQL Server, or Azure SQL backends, and extortion crews used it to steal data from hundreds of organizations at once. It is rated Critical (CVSS 9.8), scores 100% EPSS, has confirmed ransomware use, and has been on the KEV list since June 2023. Managed file transfer servers remain the single most profitable target class for extortion groups.

Do this: Patch MOVEit Transfer, review database and transfer logs back to May 2023, and assume exfiltration if the system was exposed unpatched.
