Description
PDF Export Module used in DHTMLX's products Gantt and Scheduler is vulnerable to Remote Code Execution due to lack of "data" parameter sanitization. An unauthenticated attacker can inject the malicious JavaScript code to the parameter whose value is processed by Node.js and subsequently executed. This can lead to server compromise. This issue was fixed in PDF Export Module version 0.7.6.
Problem types
CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
