CVE-2015-7527 is a high-severity Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') vulnerability in the Cool Video Gallery WordPress plugin, affecting versions < 2.0. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.0; sites on affected versions should update now. Disclosed December 2015, reported by Larry W. Cashdollar.

Vulnerability Overview

lib/core.php in the Cool Video Gallery plugin 1.9 for WordPress allows remote attackers to execute arbitrary code via shell metacharacters in the "Width of preview image" and possibly other input fields in the "Video Gallery Settings" page.

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-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

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 Cool Video Gallery: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Cool Video Gallery 2.0 closes this, and updating the plugin is the step that ends it.
