CVE-2021-29357
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 · uneditedThe ECT Provider component in OutSystems Platform Server 10 before 10.0.1104.0 and 11 before 11.9.0 (and LifeTime management console before 11.7.0) allows SSRF for arbitrary outbound HTTP requests.
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.

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.
-
Check OutSystems Platform Server 10 versionLocate the installed version of OutSystems Platform Server 10 (x) through the Service Center admin interface, installation logs, or system information. Look for a version number in the format 10.0.xxxx.Affected if The version is lower than 10.0.1104.0 (for example, 10.0.828.0 or any 10.0.x version below 10.0.1104.0).
-
Check OutSystems Platform Server 11 versionLocate the installed version of OutSystems Platform Server 11 through the Service Center admin interface, installation logs, or system information. Look for a version number in the format 11.x.xxx.Affected if The version is lower than 11.9.0 (for example, 11.6.0 or any 11.x version below 11.9.0).
-
Check LifeTime management console versionLocate the installed version of the LifeTime management console through the LifeTime console interface, installation logs, or system information. This is typically deployed separately from the Platform Server.Affected if The LifeTime version is lower than 11.7.0 (for example, 11.5.0 or any 11.x version below 11.7.0).
-
Verify ECT Provider component statusCheck whether the ECT (Enterprise Component Toolkit) Provider component is enabled or configured in the OutSystems environment. This can be verified through the Service Center administration console under the relevant module or component settings.Affected if The ECT Provider component is present and enabled in the OutSystems environment (the vulnerability only affects systems where this component is configured).
You are affected if any OutSystems Platform Server 10 instance is below 10.0.1104.0, any Platform Server 11 instance is below 11.9.0, or any LifeTime console is below 11.7.0, and the ECT Provider component is enabled.

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.
From vendor data10.0.1104.011.7.011.9.0
Upgrade OutSystems Platform Server to version 10.0.1104.0 or later (10.x) and 11.9.0 or later (11.x), and LifeTime to 11.7.0 or later. Additionally, restrict outbound network access from server-tier systems to minimize impact if exploitation occurs.
