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.

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.

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 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 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.

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.

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.

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

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

Bludit 3.12.0 allows admins to use a /plugin-backup-download?file=../ directory traversal approach for arbitrary file download via backup/plugin.php.

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

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'.

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

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

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

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.

ajax/profile-picture-upload.php in Bludit 3.10.0 allows authenticated users to change other users' profile pictures.

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.

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

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

A Stored Cross Site Scripting (XSS) vulnerability exists in bludit 3.13.1 via the TAGS section in login panel.

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

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 <script>alert(1)</script> 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.

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

Cross Site Scripting Vulnerability in BluditCMS v.3.14.1 allows attackers to execute arbitrary code via the Categories Friendly URL.

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

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).

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 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 attackers with knowledge of the API token to upload arbitrary files through the File API which leads to arbitrary code execution on the server. This vulnerability arises from improper handling of file uploads, enabling malicious actors to upload and execute PHP files.

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.

A session fixation vulnerability in Bludit allows an attacker to bypass the server's authentication if they can trick an administrator or any other user into authorizing a session ID of their choosing.

Bludit uses the SHA-1 hashing algorithm to compute password hashes. Thus, attackers could determine cleartext passwords with brute-force attacks due to the inherent speed of SHA-1. In addition, the salt that is computed by Bludit is generated with a non-cryptographically secure function.

Bludit uses predictable methods in combination with the MD5 hashing algorithm to generate sensitive tokens such as the API token and the user token. This allows attackers to authenticate against the Bludit API.

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.

Bludit allows user's session identifier to be set before authentication. The value of this session ID stays the same after authentication. This behavior enables an attacker to fix a session ID for a victim and later hijack the authenticated session. This issue was fixed in version 3.17.2.

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 version 3.16.2 contains a stored cross-site scripting (XSS) vulnerability in the post content functionality. The application performs client-side sanitation of content input but does not enforce equivalent sanitation on the server side. An authenticated user can inject arbitrary JavaScript into the content field of a post, which is stored and later rendered to other users without proper output encoding. When viewed, the injected script executes in the context of the victim’s browser, allowing session hijacking, credential theft, content manipulation, or other actions within the user’s privileges.
