Summary

Security vulnerabilities have been discovered in Apache’s Struts library

Vulnerability Details

**CVE-ID:**CVE-2014-0112, CVE-2014-0094, & CVE-2014-0050

**DESCRIPTION:**FlashSystem V840 model number -AC0, and –AC1 nodes use the Apache Struts library. Struts is used only by the Service Assist GUI.

CVE-2014-0112 (Apache Struts ParametersInterceptor code execution)

Apache Struts could allow a remote attacker to execute arbitrary code on the system, caused by an incomplete fix related to ParametersInterceptor and the failure to restrict access to the class parameter. An attacker could exploit this vulnerability using the class parameter to manipulate the ClassLoader used by the application server to execute arbitrary code on the system.

CVSS v2 Base Score: 7.5
