At a glance
CVE-2017-17753 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the CSV Import Export WordPress plugin, affecting versions <= 1.1. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). No fixed release has been reported yet; treat installations running this software as exposed. Disclosed December 2017, reported by Nicolas Buzy-Debat.
Vulnerability Overview
Multiple cross-site scripting (XSS) vulnerabilities in the esb-csv-import-export plugin through 1.1 for WordPress allow remote attackers to inject arbitrary web script or HTML via the (1) cie_type, (2) cie_import, (3) cie_update, or (4) cie_ignore parameter to includes/admin/views/esb-cie-import-export-page.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.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in CSV Import Export <= 1.1 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 CSV Import Export yet, so installs running <= 1.1 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 CSV Import Export: 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.
