At a glance
CVE-2022-2100 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Bulk Page Generator and Mass Page Builder WordPress plugin, affecting versions <= 1.6.4. It carries a CVSS score of 5.5 (reachable over the network; low attack complexity). The issue is fixed in version 1.6.6; sites on affected versions should update now. Disclosed June 2022, reported by Sachin Bahl.
Vulnerability Overview
The Page Generator plugin is vulnerable to Cross-Site Scripting in versions up to, and including, 1.6.4. This allows authenticated users with high privileges to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected 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 interaction from a victim user.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Bulk Page Generator and Mass Page Builder <= 1.6.4 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. For Bulk Page Generator and Mass Page Builder the fix is 1.6.6: builds <= 1.6.4 are affected, anything from 1.6.6 onward is not.
Remediation
Update to version 1.6.6, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Bulk Page Generator and Mass Page Builder: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Bulk Page Generator and Mass Page Builder 1.6.6 closes this, and updating the plugin is the step that ends it.
