Vulnerabilities

Bludit is vulnerable to Stored Cross-Site Scripting (XSS) in its page creating functionality. An authenticated attacker with page creation privileges (such as Author, Editor, or Administrator) can embed a malicious JavaScript payload in the tags field of a newly created article. This payload will be executed when a victim visits the URL of the uploaded resource. The uploaded resource itself is accessible without authentication. Critically, this vulnerability could be used to automatically create a new site administrator if the victim has enough privileges. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only versions 3.17.2 and 3.18.0 were tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

Bludit’s API plugin allows an authenticated attacker with a valid API token to upload files of any type and extension without restriction, which can then be executed, leading to Remote Code Execution. This issue was fixed in 3.18.4.

Bludit version 3.16.1 contains a cross-site request forgery (CSRF) vulnerability in the /admin/uninstall-plugin/ and /admin/install-theme/ endpoints. The application does not implement anti-CSRF tokens or other request origin validation mechanisms for these administrative actions. An attacker can induce an authenticated administrator to visit a malicious page that silently submits crafted requests, resulting in unauthorized plugin uninstallation or theme installation. This may lead to loss of functionality, execution of untrusted code via malicious themes, and compromise of system integrity.

Bludit versions before 3.13.1 contain an authenticated file download vulnerability in the Backup Plugin that allows logged-in users to access arbitrary files. Attackers can exploit the plugin's download functionality by manipulating file path parameters to read sensitive system files through directory traversal.

A security vulnerability has been identified in Bludit, allowing authenticated attackers to execute arbitrary code through the Image API. This vulnerability arises from improper handling of file uploads, enabling malicious actors to upload and execute PHP files.

Cross Site Scripting (XSS) vulnerability in Bludit CMS version 3.15, allows remote attackers to execute arbitrary code and obtain sensitive information via edit-content.php.

Permissions vulnerability found in Bludit CMS v.4.0.0 allows local attackers to escalate privileges via the role:admin parameter.

Bludit 3.9.2 is vulnerable to Remote Code Execution (RCE) via /admin/ajax/upload-images.

Bludit v3.14.1 was discovered to contain an arbitrary file upload vulnerability in the component /admin/new-content. This vulnerability allows attackers to execute arbitrary web scripts or HTML via uploading a crafted SVG file. NOTE: the product's security model is that users are trusted by the administrator to insert arbitrary content (users cannot create their own accounts through self-registration).

Bludit v3.14.1 is vulnerable to Stored Cross Site Scripting (XSS) via SVG file on site logo. NOTE: the product's security model is that users are trusted by the administrator to insert arbitrary content (users cannot create their own accounts through self-registration).

An issue in Bludit 4.0.0-rc-2 allows authenticated attackers to change the Administrator password and escalate privileges via a crafted request.

An issue was found in bludit v3.13.0, unsafe implementation of the backup plugin allows attackers to upload arbitrary files.

A vulnerability was found in Bludit 3.13.1. It has been declared as problematic. This vulnerability affects the endpoint /admin/new-content of the New Content module. The manipulation of the argument content with the input leads to cross site scripting. The attack can be initiated remotely but requires an authentication. The exploit has been disclosed to the public and may be used.

A Stored Cross Site Scripting (XSS) vulnerability exists in Bludit 3.13.1 via the About Plugin in login panel.

Cross Site Scripting (XSS) vulnerability exists in bludit 3-13-1 via the username in admin/login.

bludit v3.13.0 contains an arbitrary file deletion vulnerability in the backup plugin via the `deleteBackup' parameter.

Unrestricted File Upload in Bludit v3.8.1 allows remote attackers to execute arbitrary code by uploading malicious files via the component 'bl-kereln/ajax/upload-logo.php'.

A code injection vulnerability in backup/plugin.php of Bludit 3.13.1 allows attackers to execute arbitrary code via a crafted ZIP file.

A file upload vulnerability was discovered in the file path /bl-plugins/backup/plugin.php on Bludit version 3.12.0. If an attacker is able to gain Administrator rights they will be able to use unsafe plugins to upload a backup file and control the server.

Bludit v3.8.1 is affected by directory traversal. Remote attackers are able to delete arbitrary files via /admin/ajax/upload-profile-picture.

Bludit 3.12.0 allows stored XSS via JavaScript code in an SVG document to bl-kernel/ajax/logo-upload.php.

showAlert() in the administration panel in Bludit 3.12.0 allows XSS.

Bludit 3.10.0 allows Editor or Author roles to insert malicious JavaScript on the WYSIWYG editor. NOTE: the vendor's perspective is that this is "not a bug.

bl-kernel/security.class.php in Bludit 3.9.2 allows attackers to bypass a brute-force protection mechanism by using many different forged X-Forwarded-For or Client-IP HTTP headers.

In Bludit v3.9.2, there is a persistent XSS vulnerability in the Categories -> Add New Category -> Name field. NOTE: this may overlap CVE-2017-16636.

Bludit 3.9.2 allows remote code execution via bl-kernel/ajax/upload-images.php because PHP code can be entered with a .jpg file name, and then this PHP code can write other PHP code to a ../ pathname.

Bludit prior to 3.9.1 allows a non-privileged user to change the password of any account, including admin. This occurs because of bl-kernel/admin/controllers/user-password.php Insecure Direct Object Reference (a modified username POST parameter).

Bludit before 3.9.0 allows remote code execution for an authenticated user by uploading a php file while changing the logo through /admin/ajax/upload-logo.

bludit version 3.0.0 contains a Unrestricted Upload of File with Dangerous Type vulnerability in Content Upload in Pages Editor that can result in Remote Command Execution. This attack appear to be exploitable via malicious user have to upload a crafted payload containing PHP code.

Bludit 2.3.4 allows XSS via a user name.

In Bludit v1.5.2 and v2.0.1, an XSS vulnerability is located in the new page, new category, and edit post function body message context. Remote attackers are able to bypass the basic editor validation to trigger cross site scripting. The XSS is persistent and the request method to inject via editor is GET. To save the editor context, the followup POST method request must be processed to perform the attack via the application side. The basic validation of the editor does not allow injecting script codes and blocks the context. Attackers can inject the code by using an editor tag that is not recognized by the basic validation. Thus allows a restricted user account to inject malicious script code to perform a persistent attack against higher privilege web-application user accounts.
