I've tried killing all of the instances, reboot and run Chrome with the flag first of all, tried different machines as well. In the beta I can see the warning popup ("You are using unsupported flag.."), but CORS is still being enforced. Public version seems to ignore the flag completely.

As of Chrome 95, on MacOS and Windows, --disable-site-isolation-trials remains a required flag in order to disable web security, so the command-line arguments to Chrome seen below are still valid. (Some of the arguments are not formally supported by Chrome, as it will warn you.)

(Speculation) It is likely that Chrome requires a non-empty profile path to mitigate the high security risk of launching the browser with web security disabled on the default profile. See --user-data-dir= vs --user-data-dir=/some/path for more details below.

It is unclear when the Chromium codebase regressed, but downloading an older build of Chromium (following "Not-so-easy steps" on the Chromium download page) is the only workaround I found. I ended up using Version 77.0.3865.0, which properly disables web security with these flags.

Though passing in an empty path via --user-data-dir= works with --disable-web-security, it is not recommended for security purposes as it uses your default Chrome profile, which has active login sessions to email, etc. With Chrome security disabled, your active sessions are thus vulnerable to additional in-browser exploits.

On OS X, to open a new Chrome window - without having to close the already open windows first - pass in the additional -n flag. Make sure to specify empty string for data-dir (necessary for newer versions of Chrome, like v50 something+).

For Mac, using Safari is a good alternate option for local development purpose and the feature is built into the browser (so no need to add browser extension or launch Chrome using bash command like [open -a Google\ Chrome --args --disable-web-security --user-data-dir=""].

I need to launch chrome with 'Cookies without SameSite must be secure' turned off for our automated test suite. We're already using the --disable-web-security flag but that does not work. I also tried different permutations of --disable-features=same-site-by-default-cookies but I don't seem to have the feature name correct. What flag to I need to add to chrome launcher to ensure this is disabled?

This security vulnerability exists even if your web server forces a301 redirect back to the HTTPS site. The original HTTP request was still madeonce, exposing insecure session information.

Sometimes, when using cy.origin and especially with websites that are notunder your immediate test control, cross-origin errors may still tend to creepup. We don't recommend visiting or interacting with sites youdo not control.However, if this is necessary, most of these issues can usually be remedied byapplying` themodify obstructive third-party codeexperimental flag or bydisabling web security.

Cypress today has the concept ofmodifying obstructive code,which is code that may interfere with Cypress being able to run your webapplication. The experimentalModifyObstructiveThirdPartyCode flag provides thesame benefits of themodifyObstructiveCodeflag, but additionally applies it to third-party .js and .html that is beingeither loaded or navigated to inside your application. In addition to this, thisflag also does the following:

If you want to try this out, you can start Brave with brave-browser --js-flags=--jitless and that will disable the JIT entirely. One problem I ran into is that this disables support for WASM, which some sites and extensions use.

This means that if we want to be able to take a screenshot, we need to disable this feature. In this blogpost I'll demonstrate a few Frida hooking techniques and patterns along the way to achieve this goal.

The Transport Layer Security (TLS) protocol is an industry standard designed to help protect the privacy of information communicated over the Internet. TLS 1.2 is a standard that provides security improvements over previous versions. TLS 1.2 will eventually be replaced by the newest released standard TLS 1.3 which is faster and has improved security. This article presents recommendations to secure .NET Framework applications that use the TLS protocol.

To ensure .NET Framework applications remain secure, the TLS version should not be hardcoded. .NET Framework applications should use the TLS version the operating system (OS) supports.

Set the SchUseStrongCrypto and SystemDefaultTlsVersions registry keys to 1. See Configuring security via the Windows Registry. .NET Framework 3.5 supports the SchUseStrongCrypto flag only when an explicit TLS value is passed.

A value of false for Switch.System.Net.DontEnableSchUseStrongCrypto causes your app to use strong cryptography. A value of false for DontEnableSchUseStrongCrypto uses more secure network protocols (TLS 1.2 and TLS 1.1) and blocks protocols that are not secure. For more info, see The SCH_USE_STRONG_CRYPTO flag. A value of true disables strong cryptography for your app. This switch affects only client (outgoing) connections in your application.

If your app targets .NET Framework 4.6 or later versions, this switch defaults to false. That's a secure default, which we recommend. If your app runs on .NET Framework 4.6, but targets an earlier version, the switch defaults to true. In that case, you should explicitly set it to false.

If your app targets .NET Framework 4.7 or later versions, this switch defaults to false. That's a secure default that we recommend. If your app runs on .NET Framework 4.7 or later versions, but targets an earlier version, the switch defaults to true. In that case, you should explicitly set it to false.

The HKEY_LOCAL_MACHINE\SOFTWARE\[Wow6432Node\]Microsoft\.NETFramework\: SchUseStrongCrypto registry key has a value of type DWORD. A value of 1 causes your app to use strong cryptography. The strong cryptography uses more secure network protocols (TLS 1.2 and TLS 1.1) and blocks protocols that aren't secure. A value of 0 disables strong cryptography. For more information, see The SCH_USE_STRONG_CRYPTO flag. This registry setting affects only client (outgoing) connections in your application.

If your app targets .NET Framework 4.6 or later versions, this key defaults to a value of 1. That's a secure default that we recommend. If your app targets .NET Framework 4.5.2 or earlier versions, the key defaults to 0. In that case, you should explicitly set its value to 1.

If your app targets .NET Framework 4.7 or later versions, this key defaults to a value of 1. That's a secure default that we recommend. If your app targets .NET Framework 4.6.1 or earlier versions, the key defaults to 0. In that case, you should explicitly set its value to 1.

When it's enabled (by default, by an AppContext switch, or by the Windows Registry), .NET Framework uses the SCH_USE_STRONG_CRYPTO flag when your app initiates a TLS connection to a server. .NET Framework passes the flag to Schannel to instruct it to disable known weak cryptographic algorithms, cipher suites, and TLS/SSL protocol versions that may be otherwise enabled for better interoperability. For more information, see:

The SCH_USE_STRONG_CRYPTO flag is also passed to Schannel for client (outgoing) connections when you explicitly use the Tls11 or Tls12 enumerated values of SecurityProtocolType or SslProtocols. The SCH_USE_STRONG_CRYPTO flag is used only for connections where your application acts the role of the client. You can disable weak protocols and algorithms when your applications acts the role of the server by configuring the machine-wide Schannel registry settings.

There are two types of configuration: options (properties that requieres some value) andflags (that just enables or disables something). All flags are set in a singlePENPOT_FLAGS environment variable will have an ordered list of strings using thisformat: -.

The web administrators may force Secure and/or HttpOnly flags on the Session ID and the authentication cookies that are generated by the web applications. Modifying Set-Cookie headers to include these two options can be done using an http Load Balancing Virtual Server and Rewrite Policies on a Netscaler appliance.

Important! You cannot use the HttpOnly option when a web application requires access to Cookie contents by using a client-side script such as JavaScript or a client-side Java Applet. From the method mentioned in this article, only server-generated cookies can be rewritten, not the cookies generated by NetScaler Appliance (for ex: AppFirewall, persistence, VPN session cookies, and so on)

HttpOnly flag on NSC_AAAC and NSC_TMAS cookies is available in the 13.0-79.x and later releases (disabled and hidden by default).
Use the following commands to enable/disable the feature.

According to the Microsoft DeveloperNetwork,HttpOnly is an additional flag included in a Set-Cookie HTTP responseheader. Using the HttpOnly flag when generating a cookie helps mitigatethe risk of client side script accessing the protected cookie (if thebrowser supports it).

If the HttpOnly flag (optional) is included in the HTTP response header,the cookie cannot be accessed through client side script (again if thebrowser supports this flag). As a result, even if a cross-site scripting(XSS) flaw exists, and a user accidentally accesses a link thatexploits this flaw, the browser (primarily Internet Explorer) will notreveal the cookie to a third party.

If a browser does not support HttpOnly and a website attempts to set anHttpOnly cookie, the HttpOnly flag will be ignored by the browser, thuscreating a traditional, script accessible cookie. As a result, thecookie (typically your session cookie) becomes vulnerable to theft ormodification by malicious script.Mitigating.

According to Michael Howard, SeniorSecurity Program Manager in the Secure Windows Initiative group atMicrosoft, the majority of XSS attacks target theft of session cookies.A server could help mitigate this issue by setting the HttpOnly flag ona cookie it creates, indicating the cookie should not be accessible onthe client.
