A Cross-Site Request Forgery vulnerability exists in Filebrowser < 2.18.0 that allows attackers to create a backdoor user with admin privilege and get access to the filesystem via a malicious HTML webpage that is sent to the victim. An admin can run commands using the FileBrowser and hence it leads to RCE.
Affected configurations
| CPE | Name | Operator | Version |
|---|---|---|---|
| filebrowser:filebrowser | filebrowser | lt | 2.18.0 |
