Apache Struts 2.5.x < 2.5.12 Multiple DoS (S2-047) (S2-049)

critical Nessus Plugin ID 101548

Language:

Synopsis

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

Description

The version of Apache Struts running on the remote host is 2.5.x prior to 2.5.12. It is, therefore, affected by multiple vulnerabilities :

- A denial of service vulnerability exists when handling a specially crafted URL in a form field when the built-in URL validator is used. An unauthenticated, remote attacker can exploit this to cause the server process to overload. Note that this issue only affects version 2.5.x. (CVE-2017-7672)

- A flaw exists in unspecified Spring AOP functionality that is used to secure Struts actions. An authenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2017-9787)

- A deserialization vulnerability in Apache Commons FileUpload which could be leveraged for remote code execution. (CVE-2016-1000031)

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

Solution

Upgrade to Apache Struts version 2.5.12 or later.
Alternatively, apply the workaround referenced in the vendor advisory.
