            How to sanitize html/javascript from request.JSON in grails 3.1.10 restful service
            Asked 2019-Mar-11 at 18:00

            We have a grails 3.1.10 restful service that takes in json data on the http post. This data can contain html/javascript which is not desired.

            Using encodeAsHTML and the xss-sanitizer plugin XssSanitizerUtil.stripXSS methods I can see how to sanitize an individual string, but how can I push this to a higher scope through filters or something so that when request.JSON is used in the controller it has already been sanitized?

            Or is there already another easier way to accomplish this?

            I created an interceptor to apply to the appropriate controllers. In it I made a copy of the JSON parse(HttpServletRequest request) method. Near the end of the method where it parses the inputStream I plugged in my Sanitizer class that uses xss-sanitizer:

            I am using grails-xss-sanitizer in my grails application in v3.2.11. When I tried to upgrade my application to the latest 3.3.4. It reported below issue:

            I saw in grails 3.3.x upgrade notes:

            Spring Boot 1.5.x - supported in grails 3.3.x

            Spring Boot 1.5.x removes a number of deprecated classes, notably several of the classes within the org.springframework.boot.context.embedded package.

            If your application is referencing any of the classes within this package you will need to alter your imports to use org.springframework.boot.web.servlet instead.

            All classes in the org.springframework.boot.context.web package have been deprecated and relocated per the Spring Boot 1.4 Release Notes.

            And xss-sanitizer plugin is using the classes defined in package "org.springframework.boot.context.embedded"

            So, Is there any plans on the upgrade of xss-sanitizer plugin for grails 3.3.x or any workaround for this issue?

            There is no reasonable workaround to this other than to upgrade the plugin.

            It appears that the plugin is being upgraded; see source here https://github.com/rpalcolea/grails-xss-sanitizer/blob/master/gradle.properties that references grails version 3.3.0. You may also want to track or comment on this issue: https://github.com/rpalcolea/grails-xss-sanitizer/issues/1 since it describes the problem that you are seeing.

            As a disclaimer, we should not in general be using regex to filter nested HTML content (and really any HTML) content. But since the OP appears to be using a tool which is doing this, there may not be an easy workaround.

            The following pattern appears to work, and fires only on

            Install xss-sanitizer

            You can download it from GitHub.
            PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
