Progress MOVEit Transfer: Improper handling of Unicode encoding
Summary
Improper handling of Unicode encoding in Progress MOVEit Transfer affects versions before 2025.1.6 and 2026.0.0 before 2026.0.4. The NVD record gives CVSS 8.8 with low privileges required, while the vendor bulletin lists 7.5, so the score is disputed. The specific impact and exploit conditions are not described in the sources, but the CVE is network-reachable and requires a low-privilege account.
Affected
- MOVEit Transfer before 2025.1.6
- MOVEit Transfer 2026.0.0 to before 2026.0.4
- Versions 2025.0.8 and earlier: the vendor bulletin says to upgrade to an active, supported version; no specific patch is given for this branch.
Fixed in
- Upgrade 2025.1.x to 2025.1.6 or later
- Upgrade 2026.0.x to 2026.0.4 or later
Workaround
Unknown. No vendor workaround found; the vendor bulletin recommends upgrading.
Exploitation
- Not known to be exploited in the wild.
- CISA SSVC data lists exploitation as none and automatable as no.
- Not listed as KEV according to Strix.
- No public proof of concept found; absence in search is not proof of absence.
Our recommendation
- Identify all MOVEit Transfer instances and their versions, including internet-facing ones.
- Patch to 2025.1.6 or 2026.0.4 as part of the full bulletin batch, not this CVE alone.
- Until patched, restrict access to the web and admin interface by IP or VPN where possible.
- Review login and MFA logs for anomalies.
- Re-check exploitation status before finalising risk decisions.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
