HTTP status: 5 Sub-resource URL
Access-Control-Allow-Origin: *
Controls origins (websites) that are allowed to load data from this web service over JavaScript-based APIs as part of Cross-Origin Resource Sharing (CORS) standard. By default, a web browser will refuse to load data over XmlHttpRequest
from a website that is not in the same origin, which is a precaution against various types of data stealing attacks. The target server has to explicitly allow the origin domain using the Access-Control-Allow-Origin
(ACAO) header, or it may allow all origins to access it using a wildcard *
. The latter however creates a potential security issue if the website in question is transactional and processing sensitive data, so the wildcard should be only used on websites consciously offering public APIs.
The header sets permissive AJAX access by using wildcard origin *
. It may be OK if the website is a publicly accessible REST API but otherwise it should be not present at all
NEL: {"report_to":"network-errors","max_age":604800,"success_fraction":0.001,"failure_fraction":1.0}
Network Error Logging (NEL) defines a mechanism enabling web applications to declare a reporting policy that can be used by an user agent to report network errors for a given origin.

The header defines a generic reporting framework which allows web developers to associate a set of named reporting endpoints with an origin. Various platform features (like Content Security Policy, Network Error Reporting, and others) may use these endpoints to deliver feature-specific reports in a consistent manner.

A non-standard but widely accepted header introduced originally by Microsoft to disable "content sniffing" or heuristic content type discovery in absence or mismatch of a proper HTTP Content-Type
declaration, which led to a number of web attacks. In general, presence of the header with its only defined value of nosniff
is considered as part of a properly secured HTTP response.
Fuzzy content type guessing is disabled
+1X-Frame-Options: SAMEORIGIN
Instructs the browser if the current website can be embedded in HTML frame by another website. Since this allows the parent website to control the framed page, this creates a potential for data theft attacks ("clickjacking") and most sensitive websites won't allow them to be framed at all (deny
) or just allow parts of them to be embedded in frames created by themselves only (samesite
).
Clickjacking protection is enabled
+2X-Powered-By: ASP.NET
A non-standard and purely informational, but still very widespread header, whose only purpose is to advertise the name and optionally version of the software used to run the web server.
Read more...X-XSS-Protection: 1
Controls an Cross-Site Scripting (XSS) filters built into the majority of web browsers. The filter is usually turned on by default anyway, but requirement to set the header to 1
became part of canonical set of "secure" HTTP headers. Over time, vulnerabilities in the "sanitizing" mode filter were found, so 1; mode=block
became the recommended value. Some companies decided that they don't really need a browser-side XSS filter to mess with their web services which are XSS-free anyway and they became consciously disabling the XSS filter by setting the header to 0
.
XSS auditor is enabled in sanitization mode
