# CVE-2020-37245

> 8.7 HIGH · 🧪 PoC

## Beschreibung

Supsystic Digital Publications 1.6.9 contains a path traversal vulnerability in the Folder input field that allows attackers to access files outside the web root by injecting directory traversal sequences. Additionally, the plugin fails to sanitize input fields in publication settings, allowing stored cross-site scripting attacks through script injection in parameters like Area Width and Publication Width that execute when publications are viewed or edited.
