high Nessus Plugin ID 73763
New! Plugin Severity Now Using CVSS v3

The remote web server contains a web application that uses a Java framework that is affected by a security bypass vulnerability.


The remote web application appears to use Struts 2, a web framework that utilizes OGNL (Object-Graph Navigation Language) as an expression language. The version of Struts 2 in use is affected by a security bypass vulnerability, possibly due to an incomplete fix for ClassLoader manipulation implemented in version

Note that this plugin will only report the first vulnerable instance of a Struts 2 application.


Upgrade to version or later.
