At a glance
CVE-2015-10144 is a high-severity Unrestricted Upload of File with Dangerous Type vulnerability in the Responsive Thumbnail Slider WordPress plugin, affecting versions < 1.0.1. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 1.0.1; sites on affected versions should update now. Disclosed August 2015, reported by Arash Khazaei.
Vulnerability Overview
The Responsive Thumbnail Slider plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type sanitization in the via the image uploader in versions up to 1.0.1. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload arbitrary files on the affected sites server using a double extension which may make remote code execution possible.
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 Responsive Thumbnail Slider < 1.0.1 takes an account at Subscriber level or above. 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 Responsive Thumbnail Slider the fix is 1.0.1: builds < 1.0.1 are affected, anything from 1.0.1 onward is not.
Remediation
Update to version 1.0.1, or a newer patched version
How does WordSec protect against this?
An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: 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: Responsive Thumbnail Slider 1.0.1 closes this, and updating the plugin is the step that ends it.
