At a glance
CVE-2017-18548 is a critical-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the Note Press WordPress plugin, affecting versions < 0.1.2. 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 0.1.2; sites on affected versions should update now. Disclosed February 2017.
Vulnerability Overview
The Note Press plugin for WordPress before 0.1.2 has a SQL injection vulnerability via the s parameter. This can be exploited by unauthenticated users.
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-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Reaching this weakness in Note Press < 0.1.2 takes a caller who can reach the endpoint. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.
A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For Note Press the fix is 0.1.2: builds < 0.1.2 are affected, anything from 0.1.2 onward is not.
Remediation
Update to version 0.1.2, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Note Press: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Note Press 0.1.2 closes this, and updating the plugin is the step that ends it.
