Detailsinfo

A vulnerability has been found in Eclipse Jetty up to 9.2.x/9.3.x/9.4.x and classified as critical. Affected by this vulnerability is an unknown function of the component Content-Length Header Handler. The manipulation with an unknown input leads to a data processing vulnerability. The CWE definition for the vulnerability is CWE-19. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

In Eclipse Jetty Server, versions 9.2.x and older, 9.3.x (all non HTTP/1.x configurations), and 9.4.x (all HTTP/1.x configurations), when presented with two content-lengths headers, Jetty ignored the second. When presented with a content-length and a chunked encoding header, the content-length was ignored (as per RFC 2616). If an intermediary decided on the shorter length, but still passed on the longer body, then body content could be interpreted by Jetty as a pipelined request. If the intermediary was imposing authorization, the fake pipelined request would bypass that authorization.

The bug was discovered 06/25/2018. The weakness was published 06/26/2018 with Oracle (Website). It is possible to read the advisory at bugs.eclipse.org. This vulnerability is known as CVE-2017-7658 since 04/11/2017. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. The technical details are unknown and an exploit is not publicly available.
