At a glance
This record tracks a high-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the CP Image Store with Slideshow WordPress plugin, affecting versions < 1.0.7. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 1.0.7; sites on affected versions should update now. Disclosed July 2015, reported by Joaquin Ramirez Martinez.
Vulnerability Overview
The CP Image Store with Slideshow plugin for WordPress is vulnerable to an Arbitrary File Download in versions up to, and including, 1.0.6. This is due to insufficient path validation on the 'f' parameter. This makes it possible for unauthenticated attackers to obtain Purchase IDs, and potentially use the IDs to exploit an arbitrary file download vulnerability found in the plugin before 1.0.6.
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 CP Image Store with Slideshow < 1.0.7 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 CP Image Store with Slideshow the fix is 1.0.7: builds < 1.0.7 are affected, anything from 1.0.7 onward is not.
Remediation
Update to version 1.0.7, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to CP Image Store with Slideshow: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: CP Image Store with Slideshow 1.0.7 closes this, and updating the plugin is the step that ends it.
