CRLF injection vulnerability in the url_parse function in url.c in Wget through 1.19.1 allows remote attackers to inject arbitrary HTTP headers via CRLF sequences in the host subcomponent of a URL.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - wget: Lack of filename checking allows arbitrary file upload via FTP redirect (CVE-2016-4971)

  - wget: Cookie injection allows malicious website to write arbitrary cookie entries into cookie jar     (CVE-2018-0494)

  - CRLF injection vulnerability in the url_parse function in url.c in Wget through 1.19.1 allows remote     attackers to inject arbitrary HTTP headers via CRLF sequences in the host subcomponent of a URL.
    (CVE-2017-6508)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - wget: FTP symlink arbitrary filesystem access (CVE-2014-4877)

  - wget: Lack of filename checking allows arbitrary file upload via FTP redirect (CVE-2016-4971)

  - GNU Wget 1.12 and earlier uses a server-provided filename instead of the original URL to determine the     destination filename of a download, which allows remote servers to create or overwrite arbitrary files via     a 3xx redirect to a URL with a .wgetrc filename followed by a 3xx redirect to a URL with a crafted     filename, and possibly execute arbitrary code as a consequence of writing to a dotfile in a home     directory. (CVE-2010-2252)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

According to the version of the wget package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

  - A CRLF injection flaw was found in the way wget handled     URLs. A remote attacker could use this flaw to inject     arbitrary HTTP headers in requests, via CRLF sequences     in the host sub-component of a URL, by tricking a user     running wget into processing crafted     URLs.(CVE-2017-6508)

An update of the wget package has been released.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3464-1 advisory.

    Antti Levomki, Christian Jalio, and Joonas Pihlaja discovered that Wget incorrectly handled certain HTTP     responses. A remote attacker could use this issue to cause Wget to crash, resulting in a denial of     service, or possibly execute arbitrary code. (CVE-2017-13089, CVE-2017-13090)

    Dawid Golunski discovered that Wget incorrectly handled recursive or mirroring mode. A remote attacker     could possibly use this issue to bypass intended access list restrictions. (CVE-2016-7098)

    Orange Tsai discovered that Wget incorrectly handled CRLF sequences in HTTP headers. A remote attacker     could possibly use this issue to inject arbitrary HTTP headers. (CVE-2017-6508)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
