Improper Authentication vulnerability in Progress MOVEit Transfer.
This issue affects MOVEit Transfer: before 2025.1.5, from 2026.0.0 before 2026.0.3.
AnalysisAI
Authentication bypass in Progress MOVEit Transfer (versions before 2025.1.5, and 2026.0.0 before 2026.0.3) lets remote unauthenticated attackers defeat identity verification and gain full control over the managed file transfer server. Because MOVEit is a high-value data-exchange gateway, a successful bypass exposes all hosted files and administrative functions. No public exploit identified at time of analysis, and EPSS probability is low (0.18%, 8th percentile) despite the 9.8 CVSS, reflecting no observed exploitation yet.
Technical ContextAI
MOVEit Transfer is Progress Software's enterprise managed file transfer (MFT) platform, exposing HTTPS/SFTP/FTPS interfaces for secure business-to-business file exchange and browser-based transfers. The root cause is CWE-287 (Improper Authentication), meaning the application fails to correctly verify a user's claimed identity - for example by mishandling session tokens, credentials, or authentication state - allowing an actor to be treated as a legitimate (potentially administrative) principal without valid credentials. The single affected component is confirmed by CPE cpe:2.3:a:progress:moveit_transfer, and the CWE class places this alongside the pattern of MFT gateways being targeted precisely because they authenticate external parties over the network.
RemediationAI
Apply the vendor-released patch: upgrade MOVEit Transfer to 2026.0.3 for the 2026 branch, or to 2025.1.5 (or later) for earlier deployments, as described in the Progress fixed-issues advisory (https://docs.progress.com/bundle/moveit-transfer-release-notes-2026/page/Fixed-Issues-in-2026.0.3.html). Upgrading is the only complete fix for an authentication bypass and should be prioritized. Until patched, reduce exposure by restricting network reachability of the MOVEit web/transfer interfaces to known partner IP ranges via firewall or a reverse proxy allowlist (trade-off: may block legitimate external partners and require coordination), enforcing MFA on all accounts where supported, and closely monitoring authentication and administrative-action logs for anomalous logins or new admin accounts (trade-off: detective only, does not prevent the bypass). Do not rely on these controls as a substitute for the upgrade.
