The remote web server hosts a web application that uses a Java
framework that is affected by multiple vulnerabilities.
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.
Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.
