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 βProblem Reportβ 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 userβs browser session.
(CVE-2015-5169)
Note that Nessus has not tested for these issues but has instead relied only on the applicationβs self-reported version number.
