At a glance
CVE-2015-1614 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Image Metadata Cruncher WordPress plugin, affecting versions <= 1.8. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed February 2015, reported by Kaustubh G. Padwad.
Vulnerability Overview
Multiple cross-site request forgery (CSRF) vulnerabilities in the Image Metadata Cruncher plugin for WordPress allow remote attackers to hijack the authentication of administrators for requests that conduct cross-site scripting (XSS) attacks via the (1) image_metadata_cruncher[alt] or (2) image_metadata_cruncher[caption] parameter in an update action in the image_metadata_cruncher_title page to wp-admin/options.php or (3) custom image meta tag to the image metadata cruncher page.
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.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Image Metadata Cruncher <= 1.8 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. No fixed build of this plugin is recorded for Image Metadata Cruncher yet, so installs running <= 1.8 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 Image Metadata Cruncher: 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.
