At a glance
CVE-2019-17661 is a medium-severity Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') vulnerability in the Admin Columns Pro WordPress plugin, affecting versions <= 6.4.9. It carries a CVSS score of 4.4 (reachable over the network). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 6.4.10; sites on affected versions should update now. Disclosed October 2019, reported by Evgeni Sabev.
Vulnerability Overview
The Admin Columns Pro plugin for WordPress is vulnerable to CSV Injection via the export functionality in all versions up to, and including 6.4.9. This makes it possible for authenticated attackers, with subscriber-level access and above, to embed untrusted input into their profile that may appear in an exported CSV files. This can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration. While the CVE references the free version of the plugin, we did not find any export functionality in the free version which leads us to believe this is only present in the premium version.
Technical Analysis
The vector marks this flaw as remotely reachable over the network.
CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
Remediation
Update to version 6.4.10, or a newer patched version
How does WordSec protect against this?
An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Admin Columns Pro 6.4.10 closes this, and updating the plugin is the step that ends it.
