HighCVE-2024-13800

Popup Plugin For WordPress - ConvertPlus <= 3.5.30 - Missing Authorization to Authenticated (Subscriber+) Limited Options Update

ConvertPlus: Currently marked unpatched

Affected versions: *-3.5.30

Vulnerability type: CWE-862 Missing Authorization

Affected software, patched versions and attribution

The ConvertPlus plugin for WordPress is vulnerable to unauthorized modification of data that can lead to a denial of service due to a missing capability check on the 'cp_dismiss_notice' AJAX endpoint in all versions up to, and including, 3.5.30. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update option values to '1' on the WordPress site. This can be leveraged to update an option that would create an error on the site and deny service to legitimate users or be used to set some values to true such as registration.

ConvertPlus <= 3.5.26 - Authenticated (Contributor+) PHP Object Injection

ConvertPlus: Currently marked unpatched

Affected versions: *-3.5.26

Vulnerability type: CWE-502 Deserialization of Untrusted Data

Affected software, patched versions and attribution

The ConvertPlus plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.5.26 via deserialization of untrusted input from the 'settings_encoded' attribute of the 'smile_modal' shortcode. This makes it possible for authenticated attackers, with contributor-level access and above, to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
