UltimatememberCVEs & Vulnerabilities

An issue was discovered in the Ultimate Member plugin before 2.1.12 for WordPress, aka Unauthenticated Privilege Escalation via User Meta. An attacker could supply an array parameter for sensitive metadata, such as the wp_capabilities user meta that defines a user's role. During the registration process, submitted registration details were passed to the update_profile function, and any metadata was accepted, e.g., wp_capabilities[administrator] for Administrator access.

The Ultimate Member WordPress plugin before 2.6.7 does not prevent visitors from creating user accounts with arbitrary capabilities, effectively allowing attackers to create administrator accounts at will. This is actively being exploited in the wild.

The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to SQL Injection via the 'sorting' parameter in versions 2.1.3 to 2.8.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the several parameters in all versions up to, and including, 2.8.3 due to insufficient input sanitization and output escaping.

The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to second-order SQL Injection via filenames in all versions up to, and including, 2.9.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with access to upload files and manage filenames through a third-party plugin like a File Manager, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The risk of this vulnerability is very minimal as it requires a user to be able to manipulate filenames in order to successfully exploit.

The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 2.9.1 through different error messages in the responses.

Cross-Site Request Forgery (CSRF) vulnerability in Ultimate Member plugin <= 2.6.0 versions.

The JobBoardWP WordPress plugin before 1.2.2 does not properly validate file names and types in its file upload functionalities, allowing unauthenticated users to upload arbitrary files such as PHP.

The Ultimate Member plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 2.5.0 via the populate_dropdown_options function that accepts user supplied input and passes it through call_user_func(). This is restricted to non-parameter PHP functions like phpinfo(); since user supplied parameters are not passed through the function. This makes it possible for authenticated attackers, with administrative privileges, to execute code on the server.

The Ultimate Member plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 2.5.0 via the get_option_value_from_callback function that accepts user supplied input and passes it through call_user_func(). This makes it possible for authenticated attackers, with administrative capabilities, to execute code on the server.

The Ultimate Member plugin for WordPress is vulnerable to directory traversal in versions up to, and including 2.5.0 due to insufficient input validation on the 'template' attribute used in shortcodes. This makes it possible for attackers with administrative privileges to supply arbitrary paths using traversal (../../) to access and include files outside of the intended directory. If an attacker can successfully upload a php file then remote code execution via inclusion may also be possible. Note: for users with less than administrative capabilities, /wp-admin access needs to be enabled for that user in order for this to be exploitable by those users.

A vulnerability, which was classified as critical, has been found in Ultimate Member Plugin up to 2.5.0. This issue affects the function load_template of the file includes/core/class-shortcodes.php of the component Template Handler. The manipulation of the argument tpl leads to pathname traversal. The attack may be initiated remotely. Upgrading to version 2.5.1 is able to address this issue. The name of the patch is e1bc94c1100f02a129721ba4be5fbc44c3d78ec4. It is recommended to upgrade the affected component. The identifier VDB-213545 was assigned to this vulnerability.

The Ultimate Member plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Biography field featured on individual user profile pages due to insufficient input sanitization and output escaping that allows users to encode malicious web scripts with HTML encoding that is reflected back on the page. This affects versions up to, and including, 2.3.2. Please note this issue was only partially fixed in version 2.3.2.

The Ultimate Member plugin for WordPress is vulnerable to arbitrary redirects due to insufficient validation on supplied URLs in the social fields of the Profile Page, which makes it possible for attackers to redirect unsuspecting victims in versions up to, and including, 2.3.1.

The JobBoardWP WordPress plugin is vulnerable to Stored Cross-Site Scripting due to insufficient input validation and sanitization via several parameters found in the ~/includes/admin/class-metabox.php file which allowed attackers with administrative user access to inject arbitrary web scripts, in versions up to and including 1.0.7. This affects multi-site installations where unfiltered_html is disabled for administrators, and sites where unfiltered_html is disabled.

The Ultimate Member – User Profile, User Registration, Login & Membership Plugin WordPress plugin before 2.1.20 did not properly sanitise, validate or encode the query string when generating a link to edit user's own profile, leading to an authenticated reflected Cross-Site Scripting issue. Knowledge of the targeted username is required to exploit this, and attackers would then need to make the related logged in user open a malicious link.

The Ultimate Member plugin before 2.1.13 for WordPress mishandles hidden name="timestamp" fields in forms.

An issue was discovered in the Ultimate Member plugin before 2.1.12 for WordPress, aka Unauthenticated Privilege Escalation via User Roles. Due to the lack of filtering on the role parameter that could be supplied during the registration process, an attacker could supply the role parameter with a WordPress capability (or any custom Ultimate Member role) and effectively be granted those privileges.

An issue was discovered in the Ultimate Member plugin before 2.1.12 for WordPress, aka Authenticated Privilege Escalation via Profile Update. Any user with wp-admin access to the profile.php page could supply the parameter um-role with a value set to any role (e.g., Administrator) during a profile update, and effectively escalate their privileges.

Multiple Insecure Direct Object Reference vulnerabilities in includes/core/class-files.php in the Ultimate Member plugin through 2.1.2 for WordPress allow remote attackers to change other users' profiles and cover photos via a modified user_id parameter. This is related to ajax_image_upload and ajax_resize_image.

An issue was discovered in the Ultimate Member plugin 2.39 for WordPress. It allows unauthorized profile and cover picture modification. It is possible to modify the profile and cover picture of any user once one is connected. One can also modify the profiles and cover pictures of privileged users. To perform such a modification, one first needs to (for example) intercept an upload-picture request and modify the user_id parameter.

An arbitrary password reset issue was discovered in the Ultimate Member plugin 2.39 for WordPress. It is possible (due to lack of verification and correlation between the reset password key sent by mail and the user_id parameter) to reset the password of another user. One only needs to know the user_id, which is publicly available. One just has to intercept the password modification request and modify user_id. It is possible to modify the passwords for any users or admin WordPress Ultimate Members. This could lead to account compromise and privilege escalation.

A CSRF vulnerability in a logged-in user's profile edit form in the Ultimate Member plugin before 2.0.40 for WordPress allows attackers to become admin and subsequently extract sensitive information and execute arbitrary code. This occurs because the attacker can change the e-mail address in the administrator profile, and then the attacker is able to reset the administrator password using the WordPress "password forget" form.

Multiple cross-site scripting (XSS) vulnerabilities in includes/core/um-actions-login.php in the "Ultimate Member - User Profile & Membership" plugin before 2.0.28 for WordPress allow remote attackers to inject arbitrary web script or HTML via the "Primary button Text" or "Second button text" field.
