At a glance

CVE-2014-5460 is a high-severity Unrestricted Upload of File with Dangerous Type vulnerability in the Slideshow Gallery LITE WordPress plugin, affecting versions < 1.4.7. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 1.4.7; sites on affected versions should update now. Disclosed August 2014, reported by Jesús Ramírez Pichardo.

Vulnerability Overview

Unrestricted file upload vulnerability in the Tribulant Slideshow Gallery plugin before 1.4.7 for WordPress allows remote authenticated users to execute arbitrary code by uploading a PHP file, then accessing it via a direct request to the file in wp-content/uploads/slideshow-gallery/.

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-434: Unrestricted Upload of File with Dangerous Type

Reaching this weakness in Slideshow Gallery LITE < 1.4.7 takes a caller who can reach the endpoint. An unrestricted file upload lets a caller store a file whose type or destination the application does not properly constrain.

If an uploaded file lands anywhere the server will execute, the flaw becomes remote code execution and the site should be treated as fully compromised. For Slideshow Gallery LITE the fix is 1.4.7: builds < 1.4.7 are affected, anything from 1.4.7 onward is not.

Remediation

Update to version 1.4.7, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Slideshow Gallery LITE: 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: Slideshow Gallery LITE 1.4.7 closes this, and updating the plugin is the step that ends it.
