Vulnerabilities

phpList before 3.6.15 is vulnerable to Cross-Site Scripting (XSS) due to improper input sanitization in lt.php. The vulnerability is exploitable when the application dynamically references internal paths and processes untrusted input without escaping, allowing an attacker to inject malicious JavaScript.

An issue was discovered in phpList before 3.6.14. Due to an access error, it was possible to manipulate and edit data of the system's super admin, allowing one to perform an account takeover of the user with super-admin permission. Specifically, for a request with updatepassword=1, a modified request (manipulating both the ID parameter and the associated username) can bypass the intended email confirmation requirement. For example, the attacker can start from an updatepassword=1 request with their own ID number, and change the ID number to 1 (representing the super admin account) and change the username to admin2. In the first step, the attacker changes the super admin's email address to one under the attacker's control. In the second step, the attacker performs a password reset for the super admin account. The new password allows login as the super admin, i.e., a successful account takeover.

A vulnerability was found in PHPList 3.2.6 and classified as critical. This issue affects some unknown processing of the file /lists/index.php of the component Edit Subscription. The manipulation leads to sql injection. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 3.3.1 is able to address this issue. It is recommended to upgrade the affected component.

Remote Code Execution vulnerability in phplist 3.5.1. The application does not check any file extensions stored in the plugin zip file, Uploading a malicious plugin which contains the php files with extensions like PHP,phtml,php7 will be copied to the plugins directory which would lead to the remote code execution

A stored cross site scripting (XSS) vulnerability in phplist 3.5.4 and below allows authenticated attackers to execute arbitrary web scripts or HTML via a crafted payload in the "admin" parameter under the "Manage administrators" module.

A stored cross site scripting (XSS) vulnerability in phplist 3.5.3 allows attackers to execute arbitrary web scripts or HTML via a crafted payload entered into the "Add a list" field under the "Import Emails" module.

phpList 3.5.3 allows type juggling for login bypass because == is used instead of === for password hashes, which mishandles hashes that begin with 0e followed by exclusively numerical characters.

phpList 3.6.0 allows CSV injection, related to the email parameter, and /lists/admin/ exports.

phpList 3.5.9 allows SQL injection by admins who provide a crafted fourth line of a file to the "Config - Import Administrators" page.

An issue was discovered in phpList through 3.5.4. An error-based SQL Injection vulnerability exists via the Import Administrators section.

phpList before 3.5.4 allows XSS via /lists/admin/user.php and /lists/admin/users.php.

phpList before 3.5.3 allows XSS, with resultant privilege elevation, via lists/admin/template.php.

phpList 3.5.0 allows type juggling for admin login bypass because == is used instead of === for password hashes, which mishandles hashes that begin with 0e followed by exclusively numerical characters.
