Vulnerability Overview
The Go Pricing - WordPress Responsive Pricing Tables plugin for WordPress is vulnerable to unauthorized arbitrary file uploads due to an improper capability check on the 'validate_upload' function in versions up to, and including, 3.3.19. This makes it possible for authenticated attackers with a role that the administrator previously granted access to the plugin to upload arbitrary files on the affected site's server which may make remote code execution possible.
Technical Analysis
The vector marks this flaw as remotely reachable over the network. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-285: Improper Authorization
Go Pricing - WordPress Responsive Pricing Tables <= 3.3.19 carries this weakness at validate_upload, and reaching it takes a caller who can reach the endpoint. Improper authorization means a permission check exists but does not cover the case being exercised, so a caller who is allowed to do one thing is allowed to do a neighbouring thing as well.
A lower-privileged account performs an action reserved for a higher one, which on a multi-author or membership site means an ordinary user reaching administrative behaviour. For Go Pricing - WordPress Responsive Pricing Tables the fix is 3.4: builds <= 3.3.19 are affected, anything from 3.4 onward is not.
Remediation
Update to version 3.4, 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: Go Pricing - WordPress Responsive Pricing Tables 3.4 closes this, and updating the plugin is the step that ends it.
