At a glance

CVE-2012-1785 is a high-severity Improper Control of Generation of Code ('Code Injection') vulnerability in the Videopack WordPress plugin, affecting versions < 2.0. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 2.0; sites on affected versions should update now. Disclosed February 2012.

Vulnerability Overview

The Videopack (formerly Video Embed & Thumbnail Generator) plugin for WordPress is vulnerable to remote code execution in versions up to 2.0 due to insufficient input validation on data supplied to the runCom() function that executes code. This makes it possible for attackers to run arbitrary code on the system.

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, integrity, availability — full site compromise territory.

CWE-94: Improper Control of Generation of Code ('Code Injection')

Videopack < 2.0 carries this weakness at runCom(), and reaching it takes a caller who can reach the endpoint. Code injection means input from a request reaches a language construct that evaluates code, so the attacker's text is executed rather than treated as data.

The injected code runs with the web server's privileges, giving the attacker the same access to the database and filesystem as WordPress itself. For Videopack the fix is 2.0: builds < 2.0 are affected, anything from 2.0 onward is not.

Remediation

Update to version 2.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Videopack: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Videopack 2.0 closes this, and updating the plugin is the step that ends it.
