At a glance

This record tracks a critical-severity Improper Privilege Management vulnerability in the Ya'aburnee - Magazine & E-Commerce Theme WordPress theme, affecting versions <= 1.0.7. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed March 2015, reported by Evex.

Vulnerability Overview

The Ya'aburnee and Dignitas themes for WordPress are vulnerable to Privilege Escalation in versions up to, and including, 1.0.7 and 1.1.9 via the 'df_save_options' function. This makes it possible for unauthenticated attackers to escalate their privileges on the vulnerable service and gain otherwise restricted access to Admin 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 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-269: Improper Privilege Management

Ya'aburnee - Magazine & E-Commerce Theme <= 1.0.7 carries this weakness at df_save_options, and reaching it takes a caller who can reach the endpoint. Improper privilege management means the code lets an account end up with capabilities its role should not have.

It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. No fixed build of this theme is recorded for Ya'aburnee - Magazine & E-Commerce Theme yet, so installs running <= 1.0.7 stay exposed until the vendor ships one.

Remediation

No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.

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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
