At a glance
CVE-2014-10397 is a high-severity Unrestricted Upload of File with Dangerous Type vulnerability in the Antioch WordPress theme, affecting versions <= 1.3. 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 September 2014, reported by Ashiyane Digital Security Team.
Vulnerability Overview
The Antioch theme through 2014-09-07 for WordPress allows arbitrary file downloads via the file parameter to lib/scripts/download.php.
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-434: Unrestricted Upload of File with Dangerous Type
Reaching this weakness in Antioch <= 1.3 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. No fixed build of this theme is recorded for Antioch yet, so installs running <= 1.3 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 Antioch: 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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
