Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2017-6325 impacting symantec messaging_gateway. Evaluated with CVSS Base Score of 6.6 (MEDIUM).

Original NVD Description

Source: NIST NVD
The Symantec Messaging Gateway can encounter a file inclusion vulnerability, which is a type of vulnerability that is most commonly found to affect web applications that rely on a scripting run time. This issue is caused when an application builds a path to executable code using an attacker-controlled variable in a way that allows the attacker to control which file is executed at run time. This file inclusion vulnerability subverts how an application loads code for execution. Successful exploitation of a file inclusion vulnerability will result in remote code execution on the web server that runs the affected web application.
