Boltcms Bolt 3.6.6

The foldername parameter in Bolt 5.1.7 was discovered to have incorrect input validation, allowing attackers to perform directory enumeration or cause a Denial of Service (DoS) via a crafted input.

Bolt CMS <= 4.2 is vulnerable to Remote Code Execution. Unsafe theme rendering allows an authenticated attacker to edit theme to inject server-side template injection that leads to remote code execution.

Controller/Backend/FileEditController.php and Controller/Backend/FilemanagerController.php in Bolt before 4.1.13 allow Directory Traversal.

Bolt before 3.7.2 does not restrict filter options in a Request in the Twig context, and is therefore inconsistent with the "How to Harden Your PHP for Better Security" guidance.

In Bolt CMS before version 3.7.1, the filename of uploaded files was vulnerable to stored XSS. It is not possible to inject javascript code in the file name when creating/uploading the file. But, once created/uploaded, it can be renamed to inject the payload in it. Additionally, the measures to prevent renaming the file to disallowed filename extensions could be circumvented. This is fixed in Bolt 3.7.1.

Bolt CMS before version 3.7.1 lacked CSRF protection in the preview generating endpoint. Previews are intended to be generated by the admins, developers, chief-editors, and editors, who are authorized to create content in the application. But due to lack of proper CSRF protection, unauthorized users could generate a preview. This has been fixed in Bolt 3.7.1

Bolt before 3.6.10 has XSS via createFolder or createFile in Controller/Async/FilesystemManager.php.

Bolt before 3.6.10 has XSS via an image's alt or title field.

Bolt before 3.6.10 has XSS via a title that is mishandled in the system log.

Cross Site Request Forgery (CSRF) in the bolt/upload File Upload feature in Bolt CMS 3.6.6 allows remote attackers to execute arbitrary code by uploading a JavaScript file to include executable extensions in the file/edit/config/config.yml configuration file.
