## What is CVE-2018-9078?

CVE-2018-9078 is a high-severity cross-site scripting vulnerability in Lenovo Group LTD EZ Media and Backup Center, published on 28 Sep 2018. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

For some Iomega, Lenovo, LenovoEMC NAS devices versions 4.1.402.34662 and earlier, the Content Explorer application grants users the ability to upload files to shares and this image was rendered in the browser in the device's origin instead of prompting to download the asset. The application does not prevent the user from uploading SVG images and returns these images within their origin. As a result, malicious users can upload SVG images that contain arbitrary JavaScript that is evaluated when the victim issues a request to download the file.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)
