At a glance
CVE-2020-9514 is a high-severity Missing Authorization vulnerability in the IMPress for IDX Broker WordPress plugin, affecting versions < 2.6.2. It carries a CVSS score of 8.1 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires an authenticated account. The issue is fixed in version 2.6.2; sites on affected versions should update now. Disclosed March 2020, reported by Ram.
Vulnerability Overview
An issue was discovered in the IMPress for IDX Broker plugin before 2.6.2 for WordPress. wrappers.php allows a logged-in user (with the Subscriber role) to permanently delete arbitrary posts and pages, create new posts with arbitrary subjects, and modify the subjects of existing posts and pages (via create_dynamic_page and delete_dynamic_page). This is due to missing capability and nonce checks on two of its Ajax actions.
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 interaction from a victim user. A successful exploit has high impact on integrity, availability.
CWE-862: Missing Authorization
Reaching this weakness in IMPress for IDX Broker < 2.6.2 takes any authenticated account. 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 IMPress for IDX Broker the fix is 2.6.2: builds < 2.6.2 are affected, anything from 2.6.2 onward is not.
Remediation
Update to version 2.6.2, 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: IMPress for IDX Broker 2.6.2 closes this, and updating the plugin is the step that ends it.
