Vulnerability Overview

The s3bubble-amazon-s3-audio-streaming plugin 2.0 for WordPress has directory traversal via the adverts/assets/plugins/ultimate/content/downloader.php path parameter.

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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Reaching this weakness in S3Bubble Cloud Video with Adverts and Analytics < 4.8 takes a caller who can reach the endpoint. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.

Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For S3Bubble Cloud Video with Adverts and Analytics the fix is 4.8: builds < 4.8 are affected, anything from 4.8 onward is not.

Remediation

Update to version 4.8, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to S3Bubble Cloud Video with Adverts and Analytics: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: S3Bubble Cloud Video with Adverts and Analytics 4.8 closes this, and updating the plugin is the step that ends it.
