Overview

org.apache.struts:struts2-core is a popular open-source framework for developing web applications in the Java programming language.

Affected versions of this package are vulnerable to Denial of Service when certain fields exceed the maxStringLength limit during multipart requests. An attacker can exploit this to leave uploaded files in the struts.multipart.saveDir even after the request has been denied resulting in excessive disk usage.
