At a glance
CVE-2014-9735 is a critical-severity Missing Authorization vulnerability in the Showbiz Pro Responsive Teaser WordPress Plugin WordPress plugin, affecting versions < 1.7.1. 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 1.7.1; sites on affected versions should update now. Disclosed November 2014, reported by Simo Ben youssef.
Vulnerability Overview
The ThemePunch Slider Revolution (revslider) plugin before 3.0.96 for WordPress and Showbiz Pro plugin 1.7.1 and earlier for Wordpress does not properly restrict access to administrator AJAX functionality, which allows remote attackers to (1) upload and execute arbitrary files via an update_plugin action; (2) delete arbitrary sliders via a delete_slider action; and (3) create, (4) update, (5) import, or (6) export arbitrary sliders via unspecified vectors. Several WordPress themes utilize revslider which makes them vulnerable as well.
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 Showbiz Pro Responsive Teaser WordPress Plugin < 1.7.1 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 Showbiz Pro Responsive Teaser WordPress Plugin the fix is 1.7.1: builds < 1.7.1 are affected, anything from 1.7.1 onward is not.
Remediation
Update to version 1.7.1, 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: Showbiz Pro Responsive Teaser WordPress Plugin 1.7.1 closes this, and updating the plugin is the step that ends it.
