CVE-2019-15819
At a glance
CVE-2019-15819 is a critical-severity Missing Authorization vulnerability in the Restaurant Reservations WordPress plugin, affecting versions <= 1.3. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.5; sites on affected versions should update now. Disclosed August 2019, reported by Jerome Bruandet.
Vulnerability Overview
The ND Restaurant Reservations plugin before 1.5 for WordPress is vulnerable to unauthenticated option changes via the nd_rst_import_settings_php_function. This allows unauthenticated attackers to change arbitrary site options, including options that can allow site takeover, such as setting the default role to administrator.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-862: Missing Authorization
Reaching this weakness in Restaurant Reservations <= 1.3 takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Restaurant Reservations the fix is 1.5: builds <= 1.3 are affected, anything from 1.5 onward is not.
Remediation
Update to version 1.5, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Restaurant Reservations 1.5 closes this, and updating the plugin is the step that ends it.
