Apache Struts 2.3.5 - 2.3.31 / 2.5.x < 2.5.10.1 Jakarta Multipart Parser RCE (S2-045) (S2-046)

critical Nessus Plugin ID 97576

Language:

Synopsis

The remote host contains a web application that uses a Java framework that is affected by a remote code execution vulnerability.

Description

The version of Apache Struts running on the remote host is 2.3.5 through 2.3.31 or else 2.5.x prior to 2.5.10.1. It is, therefore, affected by a remote code execution vulnerability in the Jakarta Multipart parser due to improper handling of the Content-Type, Content-Disposition, and Content-Length headers. An unauthenticated, remote attacker can exploit this, via a specially crafted header value in the HTTP request, to potentially execute arbitrary code.

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

Solution

Upgrade to Apache Struts version 2.3.32 / 2.5.10.1 or later.
Alternatively, apply the workaround referenced in the vendor advisory.
