At a glance

CVE-2014-1907 is a critical-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Broadcast Live Video WordPress plugin, affecting versions < 4.29.5. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 4.29.5; sites on affected versions should update now. Disclosed February 2014, reported by High-Tech Bridge Security Research Lab.

Vulnerability Overview

Multiple directory traversal vulnerabilities in the VideoWhisper Live Streaming Integration plugin before 4.29.5 for WordPress allow remote attackers to (1) read arbitrary files via a .. (dot dot) in the s parameter to ls/rtmp_login.php or (2) delete arbitrary files via a .. (dot dot) in the s parameter to ls/rtmp_logout.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, integrity, availability — full site compromise territory.

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

Reaching this weakness in Broadcast Live Video < 4.29.5 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 Broadcast Live Video the fix is 4.29.5: builds < 4.29.5 are affected, anything from 4.29.5 onward is not.

Remediation

Update to version 4.29.5, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Broadcast Live Video: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Broadcast Live Video 4.29.5 closes this, and updating the plugin is the step that ends it.
