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.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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. (CVE-2017-7658)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2017-7658)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the K10002140 advisory.

  - In Eclipse Jetty, versions 9.2.x and older, 9.3.x (all configurations), and 9.4.x (non-default     configuration with RFC2616 compliance enabled), transfer-encoding chunks are handled poorly. The chunk     length parsing was vulnerable to an integer overflow. Thus a large chunk size could be interpreted as a     smaller chunk size and content sent as chunk body could be interpreted as a pipelined request. If Jetty     was deployed behind an intermediary that imposed some authorization and that intermediary allowed     arbitrarily large chunks to be passed on unchanged, then this flaw could be used to bypass the     authorization imposed by the intermediary as the fake pipelined request would not be interpreted by the     intermediary as a request. (CVE-2017-7657)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
