CVE-2024-6482: login with phone number vulnerability

What is known

The Login with phone number plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.7.49. This is due to a lack of validation and missing capability check on user-supplied data in the 'lwp_update_password_action' function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update their role to any other role, including Administrator. The vulnerability was partially patched in version 1.7.40. The login with phone number pro plugin was required to exploit the vulnerability in versions 1.7.40 - 1.7.49.

Business impact

Successful exploitation of CVE-2024-6482, a high vulnerability (CVSS 8.8) affecting login with phone number, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether login with phone number is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
