Apache Struts Commons FileUpload Library Remote Code Execution Vulnerability Affecting Cisco Products: November 2018

On November 5, 2018, the Apache Struts Team released a security announcement urging an upgrade of the Commons FileUpload library to version 1.3.3 on systems using Struts 2.3.36 or earlier releases. Systems using earlier versions of this library may be exposed to attacks that could allow execution of arbitrary code or modifications of files on the system. The issue is caused by a previously reported vulnerability of the Apache Commons FileUpload library, assigned to CVE-2016-1000031. The vulnerability is due to insufficient validation of user-supplied input by the affected software. An attacker could exploit this vulnerability by submitting crafted data to an affected system. A successful exploit could allow the attacker to execute arbitrary code or manipulate files on the targeted system.
