Apache Struts 2.x < Multiple Vulnerabilities (S2-020)

high Nessus Plugin ID 117393
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


A web application running on the remote host uses a Java framework that is affected by multiple vulnerabilities.


The version of Apache Struts running on the remote host is 2.x prior to It, therefore, is affected by multiple vulnerabilities:

- A denial of service vulnerability exists in MultipartStrea.java in Apache Commons FileUpload due to failure to handle exceptional conditions. A remote, unauthenticated attacker can exploit this issue to cause the application to enter an infinite loop which may cause a denial of service condition. (CVE-2014-0050)

- A class loader manipulation flaw exists in ParameterInterceptor due to improper validation of input data. An attacker can exploit this issue to bypass certain security restriction and manipulate the ClassLoader. (CVE-2015-0094)

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


Upgrade to Apache Struts version or later
