CVE-2019-19393
CWE-79Published: October 1, 2020· Updated: Jun 17, 2026
Official Description
The Web application on Rittal CMC PU III 7030.000 V3.00 V3.11.00_2 to V3.15.70_4 devices fails to sanitize user input on the system configurations page. This allows an attacker to backdoor the device with HTML and browser-interpreted content (such as JavaScript or other client-side scripts) as the content is always displayed after and before login. Persistent XSS allows an attacker to modify displayed content or to change the victim's information. Successful exploitation requires access to the web management interface, either with valid credentials or a hijacked session.
Technical Analysis
CVE-2019-19393 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
