attack, reported by Shailesh Suthar.

CVE-2016-2221 Wordpress could be vulnerable for an open redirection
attack which was fixed by better validation of the URL used in HTTP
redirects.

CVE-2016-2222 It was discovered that Wordpress was susceptible for a
possible Side Request Forgery Vulnerability because it considered for
instance 0.1.2.3 as a valid IP.

For Debian 6 'Squeeze', these problems have been fixed in version
3.6.1+dfsg-1~deb6u9.

We recommend that you upgrade your wordpress packages.

block directly from the DLA security advisory. Tenable has attempted

  - A cross-site redirection vulnerability exists due to a
    failure by the application to validate certain input.
    An unauthenticated, remote attacker can exploit this,
    via a specially crafted link, to redirect a victim from
    a legitimate web site to an arbitrary web site of the
    attacker's choosing, thus allowing further attacks on
    client-side software, such as web browsers or document
    rendering software. (CVE-2016-2221)

  - A server-side request forgery vulnerability exists in
    which the server can be induced into performing
    unintended actions when handling certain requests. An
    unauthenticated, remote attacker can exploit this, via
    crafted requests to certain local URIs, to conduct
    further host-based attacks, such as bypassing access
    restrictions, conducting port scanning, enumerating
    internal networks and hosts, or invoking additional
    protocols. (CVE-2016-2222)

relied only on the application's self-reported version number.");
