Apache Struts ActionForm ClassLoader Security Bypass Vulnerability
Publish date: July 21, 2015
Severity: HIGH
CVE Identifier: CVE-2014-0114
Advisory Date: JUL 21, 2015
DESCRIPTION
Apache Commons BeanUtils, as distributed in lib/commons-beanutils-1.8.0.jar in Apache Struts 1.x through 1.3.10 and in other products requiring commons-beanutils through 1.9.2, does not suppress the class property, which allows remote attackers to "manipulate" the ClassLoader and execute arbitrary code via the class parameter, as demonstrated by the passing of this parameter to the getClass method of the ActionForm object in Struts 1.
