CVE-2023-42656
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn Progress MOVEit Transfer versions released before 2021.1.8 (13.1.8), 2022.0.8 (14.0.8), 2022.1.9 (14.1.9), 2023.0.6 (15.0.6), a reflected cross-site scripting (XSS) vulnerability has been identified in MOVEit Transfer's web interface. An attacker could craft a malicious payload targeting MOVEit Transfer users during the package composition procedure. If a MOVEit user interacts with the crafted payload, the attacker would be able to execute malicious JavaScript within the context of the victims browser.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate MOVEit Transfer version numberAccess the MOVEit Transfer Admin interface, then navigate to Help > About, or check the Windows registry under HKLM\SOFTWARE\MOVEit Transfer for the installed version valueAffected if The displayed version falls within any of these ranges: < 2021.1.8, >= 2022.0.0 and < 2022.0.8, >= 2022.1.0 and < 2022.1.9, or >= 2023.0.0 and < 2023.0.6
-
Verify web interface accessibilityConfirm that the MOVEit Transfer web interface (typically on ports 80/443 or custom ports) is exposed and reachable from user networksAffected if The web interface is exposed and the version is in the affected ranges listed above
-
Confirm package composition feature exposureCheck if users have access to the package composition/procedure features in the web interface, where the XSS payload would be deliveredAffected if Users can access the package composition workflow and the installed version is vulnerable
-
Compare version against safe releasesMatch your installed version against the fixed releases: 2021.1.8 (13.1.8), 2022.0.8 (14.0.8), 2022.1.9 (14.1.9), or 2023.0.6 (15.0.6)Affected if Your version is lower than any of these fixed version numbers in your respective branch
You are affected if the MOVEit Transfer version is lower than 2021.1.8, 2022.0.8, 2022.1.9, or 2023.0.6 depending on your version branch and the web interface is accessible.
