Unsafe CSP policy is hampering security of Verizon's onesearch..

persistent tracking going on there.
P3P is a mostly abandoned standard for website privacy policy declaration that has little use today.
Please consider switching to DoNotTrack standard.
On CSP miconfiguration:

Content Security Policy
frame-ancestors 'none'; default-src 'self' -https://*.onesearch.com; script-src 'self' 'unsafe-inline' 'nonce-DUH8wO761xGKs9Odg+OtUg==' 'unsafe-eval'-https://*.onesearch.com; style-src 'self' 'unsafe-inline' -https://*.onesearch.com; img-src 'self' data: -https://*.onesearch.com; frame-src 'self'; media-src *; object-src *; connect-src -https://*.onesearch.com; font-src * data:; report-uri -https://www.onesearch.com/notracking/beacon/csp?src=privatesearch;
Policy delivery method: Content-Security-Policy
Enforcement: True
No base-uri allows attackers to inject base tags which override the base URI to an attacker-controlled origin. Set to 'none' unless you need to handle tricky relative URLs scheme

Consider adding block-all-mixed-content directive if your website is only accessible over TLS and you are certain it doesn not have any legacy plaintext resources. Otherwise you may add adding upgrade-insecure-requests directive if your website may still have some legacy plaintext HTTP resources and you want them to be still available rather than blocked

You should definitely try using 'strict-dynamic' to eliminate those long lists of trusted third-party scripts

Consider using script-src 'report-sample' as it significantly helps debugging CSP reports. See specification

Origin script-src 'unsafe-inline' allows bypassing of CSP and execution of inlined untrusted scripts. Use 'nonce-' or 'sha256-' instead

Origin script-src 'unsafe-eval' allows bypassing of CSP and execution of inlined untrusted scripts. Use 'nonce-' or 'sha256-' instead

Origin style-src 'unsafe-inline' allows bypassing of CSP and execution of inlined untrusted scripts. Use 'nonce-' or 'sha256-' instead

The img-src data: origin allows bypassing CSP and execution of inlined untrusted scripts

The font-src data: origin allows bypassing CSP and execution of inlined untrusted scripts


Content Security Policy (CSP) implemented unsafely.

This includes 'unsafe-inline' or data: inside script-src, overly broad sources such as https: inside object-src or script-src, or not restricting the sources for object-src or script-src.

L.S.

Lately I experience that loads of CSP policies for websites are not being set according to best policies.
Often CSP settings are conflicting with used technologies for a specific website.

In our case at hand there seems only JavaScript being involved.
So that will deminish the relative severity of what is being alerted.

With CSP Evaluator extension in the browser one can establish less optimal settings at a glance.
For the website mentioned -

Medium severity finding:
script-src

help_outline'self'
'self' can be problematic if you host JSONP, Angular or user uploaded files.
remove'unsafe-inline'
unsafe-inline is ignored if a nonce or a hash is present. (CSP2 and above)
check'nonce-7VEBQ7JXVhm9oEPE84mErA=='
help_outline'unsafe-eval'
'unsafe-eval' allows the execution of code injected into DOM APIs such as eval().
help_outlinehttps://*.onesearch.com
No bypass found; make sure that this URL doesn't serve JSONP replies or Angular libraries.

High severity finding:
Object-src
expand_more
error*
object-src should not allow '*' as source
Can you restrict object-src to 'none' only?

High severity finding:
base-uri [missing]
Missing base-uri allows the injection of base tags. They can be used to set the base URL for all relative (script) URLs to an attacker controlled domain. Can you set it to 'none' or 'self'?

Technology used JavaScript: JavaScript Global Variables
These are the non-standard "global" variables defined on the window object. These can be helpful in identifying possible client-side frameworks and code.

object| onformdata object| onpointerrawupdate function| _scrollIntoView object| lst object| w object| d function| _initCrypto object| YUI object| Y object| YAHOO object| items object| elems object| sbInput object| saTray boolean| ieVer boolean| stopPropertychange function| resetHighlight function| highlight number| atfCount

First we have to establish whether there are real compatibility problems (for instance with JSON or angular.js etc.
Then we have various checks for versions of CSP 1, 2, 3 and a nonce-based backwards compatibility for version 3
