CVE-2017-7658

Description

From CVE.org

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.

Statement

This issue affects the versions of jetty embedded in the nutch package as shipped with Red Hat Satellite 5. The nutch service is not exposed, as such exploitation is difficult, Red Hat Product Security has rated this issue as having security impact of Low. A future update may address this issue. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/.

Data Grid 7 has deprecated the agent-bond utility that permits this flaw; it is disabled by default and is no longer supported. While the functionality is still available for backward-compatibility usage, customers are strongly recommended to use Prometheus JMX instead. As the functionality is deprecated and no longer supported, the flaw has been scored as Moderate for Data Grid 7.

Data Grid 8 is not affected by this flaw.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)

Integrity,Non-Repudiation,Access Control

Technical Impact: Unexpected State; Hide Activities; Bypass Protection Mechanism

An attacker could create HTTP messages to exploit a number of weaknesses including 1) the message can trick the web server to associate a URL with another URL's webpage and caching the contents of the webpage (web cache poisoning attack), 2) the message can be structured to bypass the firewall protection mechanisms and gain unauthorized access to a web application, and 3) the message can invoke a script or a page that returns client credentials (similar to a Cross Site Scripting attack).
