Dolibarr ERP/CRM 9.0.1 was affected by stored XSS within uploaded files. These vulnerabilities allowed the execution of a JavaScript payload each time any regular user or administrative user clicked on the malicious link hosted on the same domain. The vulnerabilities could be exploited by low privileged users to target administrators. The viewimage.php page did not perform any contextual output encoding and would display the content within the uploaded file with a user-requested MIME type.

Dolibarr ERP/CRM 9.0.1 provides a module named website that provides for creation of public websites with a WYSIWYG editor. It was identified that the editor also allowed inclusion of dynamic code, which can lead to code execution on the host machine. An attacker has to check a setting on the same page, which specifies the inclusion of dynamic content. Thus, a lower privileged user of the application can execute code under the context and permissions of the underlying web server.

Dolibarr ERP/CRM 9.0.1 provides a web-based functionality that backs up the database content to a dump file. However, the application performs insufficient checks on the export parameters to mysqldump, which can lead to execution of arbitrary binaries on the server. (Malicious binaries can be uploaded by abusing other functionalities of the application.)
