At a glance

This record tracks a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the IP Blacklist Cloud WordPress plugin, affecting versions < 3.43. It carries a CVSS score of 4.9 (reachable over the network; low attack complexity; high confidentiality impact). The issue is fixed in version 3.43; sites on affected versions should update now. Disclosed March 2015, reported by James Hooker.

Vulnerability Overview

The IP Blacklist Cloud plugin for WordPress is vulnerable to Directory Traversal in versions before 3.43 via the importCSVIPCloud function. This allows authenticated attackers with high-level privileges to read the contents of arbitrary files on the server, which can contain sensitive information.

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 interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in IP Blacklist Cloud < 3.43 takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For IP Blacklist Cloud the fix is 3.43: builds < 3.43 are affected, anything from 3.43 onward is not.

Remediation

Update to version 3.43, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: IP Blacklist Cloud 3.43 closes this, and updating the plugin is the step that ends it.
