Apache Struts 2.0.0 through 2.3.x before 2.3.20 uses predictable <s:token/> values, which allows remote attackers to bypass the CSRF protection mechanism.

According to its self-reported version, the MySQL Enterprise Monitor running on the remote host may be affected by a cross-site request forgery vulnerability due to the token generator failing to adequately randomize the token values. A remote attacker can exploit this 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 attacker can then use the predicted token value 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.

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.
