CVE-2022-38186
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 · uneditedThere is a reflected XSS vulnerability in Esri Portal for ArcGIS versions 10.8.1 and below which may allow a remote attacker able to convince a user to click on a crafted link which could potentially execute arbitrary JavaScript code in the victim’s browser.
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 · moderate confidenceA reflected XSS vulnerability exists in Esri Portal for ArcGIS versions 10.8.1 and below. An attacker can craft a malicious URL containing JavaScript payload that executes in the victim's browser when clicked, due to improper input validation and output encoding on the affected endpoint.

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.
-
Confirm Esri Portal for ArcGIS installationIdentify whether Portal for ArcGIS is installed on the system by checking for the Portal service or installation directoryAffected if Portal for ArcGIS software is present on the system
-
Check installed Portal versionAccess the Portal Administrator Directory (typically at /portal/portaladmin) or check system information to retrieve the exact version numberAffected if Installed version is 10.8.1 or below (any version from 10.0 through 10.8.1)
-
Identify the vulnerable endpointLocate the web endpoint affected by improper input validation and output encoding - this is the specific URL parameter that accepts user input without sanitizationAffected if The endpoint with the input validation flaw is accessible and accepts unsanitized parameters
-
Verify the parameter is exploitableInspect whether the affected parameter in the URL reflects user-supplied input back into the response without proper encodingAffected if The endpoint reflects unsanitized input in its response, enabling script injection
If Portal for ArcGIS is installed and the version is 10.8.1 or below, and the vulnerable endpoint with improper input validation is accessible, the environment is affected by this reflected XSS vulnerability.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedApply vendor-supplied patch/upgrade to a fixed version (10.9+) and implement output encoding and input validation on the affected parameter to prevent script execution.
Portal for ArcGIS 10.9 or later
- Identify the current Portal for ArcGIS version in use (check the About page in Portal Admin)
- Review the Esri Product Lifecycle and patches page at https://www.esri.com/en-us/portal/overview for the fixed release
- Upgrade Portal for ArcGIS to version 10.9 or later (the first release after 10.8.1 that addresses this vulnerability)
- After upgrade, verify the XSS vulnerability is patched by testing with the originally vulnerable parameter
- Confirm normal Portal functionality works after the upgrade
