At a glance
This record tracks a high-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the multi-plugin-installer WordPress plugin, affecting versions < 1.2.0. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 1.2.0; sites on affected versions should update now. Disclosed August 2015, reported by Marcin Probola.
Vulnerability Overview
The Multi Plugin Installer plugin for WordPress is vulnerable to Arbitrary File Read in versions before 1.2.0. This is due to vulnerable parameters 'filepath' and 'filename' in the mpi_download_file function. This makes it possible for unauthenticated attackers to read arbitrary files.
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.
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
multi-plugin-installer < 1.2.0 carries this weakness at filepath, and reaching it 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 multi-plugin-installer the fix is 1.2.0: builds < 1.2.0 are affected, anything from 1.2.0 onward is not.
Remediation
Update to version 1.2.0, or a newer patched version
How does WordSec protect against this?
The fix is the thing that ends this: multi-plugin-installer 1.2.0 closes this, and updating the plugin is the step that ends it.
