CVE-2021-38159
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 certain Progress MOVEit Transfer versions before 2021.0.4 (aka 13.0.4), SQL injection in the MOVEit Transfer web application could allow an unauthenticated remote attacker to gain access to the database. Depending on the database engine being used (MySQL, Microsoft SQL Server, or Azure SQL), an attacker may be able to infer information about the structure and contents of the database, or execute SQL statements that alter or delete database elements, via crafted strings sent to unique MOVEit Transfer transaction types. The fixed versions are 2019.0.8 (11.0.8), 2019.1.7 (11.1.7), 2019.2.4 (11.2.4), 2020.0.7 (12.0.7), 2020.1.6 (12.1.6), and 2021.0.4 (13.0.4).
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSQL injection vulnerability in MOVEit Transfer web application allows unauthenticated remote attackers to gain database access via crafted strings sent to unique transaction types. Attackers can infer database structure/contents and execute/modify/delete SQL statements depending on the database engine (MySQL, MSSQL, or Azure SQL).

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.
-
Identify MOVEit Transfer versionLog into the MOVEit Transfer admin interface and navigate to Help > About, or check the version displayed on the login page. On Windows, you can also check the registry key HKLM\SOFTWARE\MOVEit Transfer\CurrentVersion or inspect the installed program's properties.Affected if The installed version falls within any of these ranges: < 2019.0.8; >= 2019.1 and < 2019.1.7; >= 2019.2 and < 2019.2.4; >= 2020.0 and < 2020.0.7; >= 2020.1 and < 2020.1.6; >= 2021.0 and < 2021.0.4
-
Confirm web application is accessibleVerify that the MOVEit Transfer web interface (typically ports 80/443 or configured IIS bindings) is reachable from the network. Check IIS site bindings or firewall rules to determine external exposure.Affected if The web application is exposed to network access (especially untrusted networks) and the version is within the affected ranges listed above
-
Verify database engine configurationCheck the MOVEit Transfer configuration files or admin settings to identify which database engine is in use (MySQL, MSSQL, or Azure SQL). This information is typically found in the installation documentation or web.config file in the installation directory.Affected if The application uses MySQL, MSSQL, or Azure SQL as its database backend and the version is vulnerable
You are affected if MOVEit Transfer is exposed as a web application and its installed version is lower than 2019.0.8, 2019.1.7, 2019.2.4, 2020.0.7, 2020.1.6, or 2021.0.4 (or falls within the specific affected ranges between these versions).

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Upgrade to fixed versions (2019.0.8, 2019.1.7, 2019.2.4, 2020.0.7, 2020.1.6, or 2021.0.4 and later) or apply vendor patches to remediate this critical vulnerability.
Upgrade to one of the fixed versions: 2019.0.8, 2019.1.7, 2019.2.4, 2020.0.7, 2020.1.6, or 2021.0.4 (recommended: latest stable 2021.0.4)
- Identify the currently installed MOVEit Transfer version by checking the application or system documentation
- Determine which upgrade path applies based on current version (2019.0.x, 2019.1.x, 2019.2.x, or 2020.0.x)
- Review the fixed versions list: 2019.0.8, 2019.1.7, 2019.2.4, 2020.0.7, 2020.1.6, or 2021.0.4
- Create a complete backup of the MOVEit Transfer database and configuration files
- Test the upgrade in a non-production environment to verify compatibility
- Apply the upgrade to the production MOVEit Transfer installation
- Verify the upgrade was successful by checking the application version
- Confirm the SQL injection vulnerability is resolved by reviewing release notes or running vulnerability scans
