"The remote web server is using a version of Struts 2 that is affected
by multiple vulnerabilities :

  - A cross-site request forgery vulnerability exists due to
    the token generator failing to adequately randomize the
    token values. An attacker can exploit this issue by
    extracting a token from a form and then predicting the
    next token value that will be used to secure form
    submissions. By convincing a victim to visit a specially
    crafted form, the predicted token value can be used to
    force an action for a logged in user. Note that this
    vulnerability can only be exploited when the <s:token/>
    tag is used within a form. (CVE-2014-7809)

  - A cross-site scripting vulnerability exists due to
    improper validation of input passed via the 'Problem
    Report' screen when using debug mode. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted request, to execute arbitrary script
    code in the context of a user's browser session.
    (CVE-2015-5169)

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