Apache Struts 2.5.x < 2.5.14.1 Json-lib JSON Parsing Unspecified DoS (S2-054) (S2-055)

critical Nessus Plugin ID 105005
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.

Synopsis

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

Description

The version of Apache Struts running on the remote host is 2.5.x prior to 2.5.14.1. It is, therefore, affected by an unspecified flaw that is triggered when parsing JSON. This allows a remote attacker to cause a denial of service.

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 2.5.14.1 or later or apply the workaround as referenced in the vendor's security bulletin.
