At a glance
This record tracks a high-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the S3 Bubble Amazon S3 HTML5 Video with Adverts WordPress plugin, affecting versions <= 2.0. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed April 2015, reported by CrashBandicot.
Vulnerability Overview
The S3 Bubble Amazon S3 HTML5 Video with Adverts plugin for WordPress is vulnerable to Arbitrary File Download in versions up to, and including, 2.0. This is due to a lack of path restriction on the 'path' parameter in the download.php file. This makes it possible for unauthenticated attackers to download any file, including configuration files, by guessing the file name and path on the WordPress installation.
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')
S3 Bubble Amazon S3 HTML5 Video with Adverts <= 2.0 carries this weakness at path, and reaching it 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. No fixed build of this plugin is recorded for S3 Bubble Amazon S3 HTML5 Video with Adverts yet, so installs running <= 2.0 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
The attempt arrives as an ordinary request to S3 Bubble Amazon S3 HTML5 Video with Adverts: WordSec's web application firewall inspects request payloads before WordPress loads them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
