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

high Nessus Plugin ID 117393


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
