**Name of the Vulnerable Software and Affected Versions**
Naviwebs Navigate CMS version 2.8
**Description**
The issue concerns an "Unrestricted Upload of File with Dangerous Type" with directory traversal in navigate upload.php, allowing authenticated attackers to achieve remote code execution. This is done via a POST request with `engine` set to 'picnik' and `id` set to '../../../navigate info.php', which enables directory traversal.
**Recommendations**
For Naviwebs Navigate CMS version 2.8, consider restricting access to the navigate upload.php file to prevent unauthorized uploads and directory traversal attacks. As a temporary workaround, restrict the `engine` parameter to prevent it from being set to 'picnik' and limit the `id` parameter to prevent directory traversal.
