CVE-2018-1000841
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 · uneditedZend.To version Prior to 5.15-1 contains a Cross Site Scripting (XSS) vulnerability in The verify.php page that can result in An attacker could execute arbitrary Javascript code in the context of the victim's browser.. This attack appear to be exploitable via HTTP POST request. This vulnerability appears to have been fixed in 5.16-1 Beta.
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 confidenceZend.To versions prior to 5.15-1 contain a stored Cross Site Scripting (XSS) vulnerability in the verify.php page. Attackers can inject malicious JavaScript via HTTP POST requests that executes in victims' browsers when the crafted payload is rendered.

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 ZendTo installation directorySearch the web server document root for the ZendTo installation, typically found in directories named 'zendto', 'ZendTo', or at the server root. Common paths include /var/www/html/zendto or C:\inetpub\wwwroot\zendto.Affected if The ZendTo software is not installed on this system.
-
Identify installed ZendTo versionCheck for a version file or changelog within the ZendTo directory. Look for files such as VERSION, version.php, changelog.txt, or README that contain the version string. Alternatively, examine the main index.php or bootstrap files for version constants.Affected if Unable to locate version information or version is 5.15-1 or higher.
-
Confirm verify.php page existsLocate verify.php in the web-accessible directory of the ZendTo installation. This file should be present in the root folder of the application.Affected if verify.php file does not exist in the ZendTo web directory.
-
Determine version vulnerability statusCompare the identified installed version against the affected range: versions prior to 5.15-1 are vulnerable. If the exact version cannot be determined, check the installation date or version control history if available.Affected if Installed version is below 5.15-1 and verify.php is present and accessible via HTTP.
A system is affected if ZendTo is installed with a version lower than 5.15-1 and the verify.php page exists and is accessible on the web server.

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 data5.15-1
Upgrade to version 5.16-1 Beta or later to obtain the vendor fix. If immediate upgrade is not feasible, implement robust input validation and output encoding on the verify.php page to neutralize malicious script injection.
