Bolt

Bolt CMS versions 3.7.0 and earlier contain a chain of vulnerabilities that together allow an authenticated user to achieve remote code execution. A user with valid credentials can inject arbitrary PHP code into the displayname field of the user profile, which is rendered unsanitized in backend templates. The attacker can then list and rename cached session files via the /async/browse/cache/.sessions and /async/folder/rename endpoints. By renaming a .session file to a path under the publicly accessible /files/ directory with a .php extension, the attacker can turn the injected code into an executable web shell. Finally, the attacker triggers the payload via a crafted HTTP GET request to the rogue file. NOTE: The vendor announced that Bolt 3 reached end-of-life after 31 December 2021.Show less

A vulnerability classified as problematic has been found in Bolt CMS 3.7.1. Affected is an unknown function of the file /bolt/editcontent/showcases of the component Showcase Creation Handler. The manipulation of the argument title/textarea leads to cross site scripting. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed that the affected release tree is end-of-life.Show less

** UNSUPPORTED WHEN ASSIGNED ** A vulnerability was found in Bolt CMS 3.7.1. It has been rated as problematic. This issue affects some unknown processing of the file /preview/page of the component Entry Preview Handler. The manipulation of the argument body leads to cross site scripting. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-273167. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed that the affected release tree is end-of-life.Show less

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.Show less

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 3.7.1Show less

Bolt 3.7.0, if Symfony Web Profiler is used, allows XSS because unsanitized search?search= input is shown on the _profiler page. NOTE: this is disputed because profiling was never intended for use in production. This is related to CVE-2018-12040Show less

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.Show less
