At a glance

CVE-2015-4616 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Easy2Map WordPress plugin, affecting versions < 1.2.5. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity impact). The issue is fixed in version 1.2.5; sites on affected versions should update now. Disclosed June 2015, reported by Larry W. Cashdollar.

Vulnerability Overview

Directory traversal vulnerability in includes/MapPinImageSave.php in the Easy2Map plugin before 1.2.5 for WordPress allows remote attackers to create arbitrary files via a .. (dot dot) in the map_id 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 interaction from a victim user. A successful exploit has high impact on integrity.

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

Reaching this weakness in Easy2Map < 1.2.5 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 Easy2Map the fix is 1.2.5: builds < 1.2.5 are affected, anything from 1.2.5 onward is not.

Remediation

Update to version 1.2.5, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Easy2Map: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Easy2Map 1.2.5 closes this, and updating the plugin is the step that ends it.
