Name of the Vulnerable Software and Affected Versions Eclipse Vert.x versions 3.0 through 3.5.1

Description The issue allows unfiltered values to inject a new header in the client request or server response, as the HttpServer response headers and HttpClient request headers do not filter carriage return and line feed characters from the header value.

Recommendations For Eclipse Vert.x versions 3.0 through 3.5.1, consider filtering carriage return and line feed characters from the header value to prevent injection of new headers in client requests or server responses. As a temporary workaround, restrict the use of sensitive headers until a patch is available.
