CVE-2018-17218
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 · uneditedAn issue was discovered in PTC ThingWorx Platform 6.5 through 8.2. There is reflected XSS in the SQUEAL search function.
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 confidenceReflected XSS vulnerability in the SQUEAL search function of PTC ThingWorx Platform versions 6.5 through 8.2. User-supplied input in the search parameter is reflected back without proper sanitization, allowing execution of arbitrary JavaScript in the context of the user's browser.

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 PTC ThingWorx Platform is installedIdentify the ThingWorx installation directory and locate the version information file or check the platform status via the ThingWorx Composer or administrative console.Affected if ThingWorx Platform is present in the environment
-
Determine the installed versionExtract the version number from the platform installation - typically found in version files, the composer interface, or platform startup logs.Affected if The installed version falls within the range 6.5.0 to 8.2.0 inclusive
-
Verify the SQUEAL search function is accessibleCheck whether the SQUEAL search feature is enabled and accessible via the ThingWorx web interface or API endpoints.Affected if The SQUEAL search function is enabled and reachable
-
Test for reflected input in the search parameterSubmit a benign test payload (such as a non-malicious string) in the search parameter of the SQUEAL search function and observe whether the input is reflected back in the response without encoding or sanitization.Affected if User-supplied input in the search parameter is reflected directly in the response without proper output encoding
The environment is affected if PTC ThingWorx Platform version 6.5.0 through 8.2.0 is running with the SQUEAL search function enabled and user input is reflected without sanitization.

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 dataApply vendor security patches for this vulnerability or upgrade to a patched version. Implement input validation and output encoding on the SQUEAL search function to neutralize malicious script injection.
