An exploit of that vulnerability (CVE-2018-11776) could make the system susceptible to attacks which could allow an attacker to execute arbitrary code on the system. Vulnerability Details CVEID: CVE-2018-11776 DESCRIPTION: Apache Struts could allow a remote attacker to execute arbitrary code on the system, caused by an error when using results with no namespace and its upper action configurations have no wildcard namespace. An attacker could exploit this vulnerability to execute arbitrary code on the system.
