CVE-2020-36692
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 · uneditedA reflected XSS via POST vulnerability in report scheduler of Sophos Web Appliance versions older than 4.3.10.4 allows execution of JavaScript code in the victim browser via a malicious form that must be manually submitted by the victim while logged in to SWA.
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 confidenceA reflected XSS vulnerability exists in the report scheduler of Sophos Web Appliance versions prior to 4.3.10.4. Attackers can inject malicious JavaScript into a form that gets reflected back and executed in the victim's browser when the authenticated user manually submits the crafted form.

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 Sophos Web Appliance installationCheck if Sophos Web Appliance is present on the system by looking for typical installation directories such as /opt/sophos-avi/ or /opt/sophos-alert/ or by running 'ls /opt/' to list Sophos-related directories.Affected if The product is not found on the system.
-
Identify installed versionLocate the version file or check the admin interface for the Sophos Web Appliance version. This is typically accessible via the web admin portal or by examining version files within the Sophos installation directory.Affected if The installed version cannot be determined or is not Sophos Web Appliance.
-
Compare version to vulnerable rangeCompare your installed version number to the affected range: versions prior to 4.3.10.4. If the version starts with 4.3.10.x, verify the specific patch level (4.3.10.4 and later are fixed).Affected if The installed version is 4.3.10.3 or earlier, or any version starting with 4.3.9, 4.3.8, or lower.
-
Verify report scheduler accessLog into the Sophos Web Appliance admin interface and navigate to the report scheduler functionality. This feature is typically found under Reporting or Scheduler sections of the web admin panel.Affected if The report scheduler module is accessible and the user can create or submit scheduled reports.
You are affected if Sophos Web Appliance is installed with a version lower than 4.3.10.4 and the report scheduler module is accessible in your environment.
