At a glance

CVE-2014-2579 is a critical-severity Cross-Site Request Forgery (CSRF) vulnerability in the Backup, Restore and Migrate your sites with XCloner WordPress plugin, affecting versions < 3.1.1. It carries a CVSS score of 9.6 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 3.1.1; sites on affected versions should update now. Disclosed April 2014, reported by High-Tech Bridge Security Research Lab.

Vulnerability Overview

Multiple cross-site request forgery (CSRF) vulnerabilities in XCloner Standalone 3.1.0 and earlier allow remote attackers to hijack the authentication of administrators for requests that (1) change the administrator password via the config task to index2.php or (2) when the enable_db_backup and sql_mem options are enabled, access the database backup functionality via the dbbackup_comp parameter in the generate action to index2.php. NOTE: vector 2 might be a duplicate of CVE-2014-2340, which is for the XCloner Wordpress plugin. NOTE: remote attackers can leverage CVE-2014-2996 with vector 2 to execute arbitrary commands.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in Backup, Restore and Migrate your sites with XCloner < 3.1.1 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Backup, Restore and Migrate your sites with XCloner the fix is 3.1.1: builds < 3.1.1 are affected, anything from 3.1.1 onward is not.

Remediation

Update to version 3.1.1, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Backup, Restore and Migrate your sites with XCloner: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Backup, Restore and Migrate your sites with XCloner 3.1.1 closes this, and updating the plugin is the step that ends it.
