ClassLoader manipulation in Apache Struts

ALTO 7.5CVE-2014-0112 · GHSA-prjv-jj26-wf8h · Published 29/04/2014 · updated 17/06/2026

Package	Affected versions	Patched versions
org.apache.struts:struts2-core Maven	`< 2.3.20`	`2.3.20`
struts apache	`≥ 2.0.0, < 2.3.16.2`	`2.3.16.2`

Description

ParametersInterceptor in Apache Struts before 2.3.20 does not properly restrict access to the getClass method, which allows remote attackers to "manipulate" the ClassLoader and execute arbitrary code via a crafted request. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-0094.
