Severity ?
6.1 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Summary
Default development error handler in Ratpack is vulnerable to HTML content injection (XSS)
Details

Versions of Ratpack from 0.9.10 through 1.7.5 are vulnerable to CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (aka. XSS) in the development error handler. An attacker can utilize this to perform XSS when an exception message contains untrusted data.

As a simplistic example: java RatpackServer startedServer = RatpackServer.start(server -> { server.handlers(chain -> chain.all(ctx -> { // User supplied query parameter String message = ctx.getRequest().getQueryParams().get("message"); // User supplied data appended to the message in an exception throw new RuntimeException("An error occurred: " + message); })); });

Impact

  • Cross-Site Scripting

Patches

This vulnerability has been patched in Ratpack version 1.7.6.

Workarounds

If you are unable to update your version of Ratpack, we recommend the following workarounds and mitigations.

  • Ensure that development mode is disabled in production.
  • Don't use real customer data (ie. untrusted user input) in development.
