At a glance
CVE-2022-2628 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the DSGVO All in one for WP WordPress plugin, affecting versions <= 4.2. It carries a CVSS score of 5.5 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 4.3; sites on affected versions should update now. Disclosed September 2022, reported by Asif Nawaz Minhas.
Vulnerability Overview
The DSGVO All in one for WP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘dsdvo_customimprinttext’ parameter in versions up to, and including, 4.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. 4.2. was intended to provide a fix, but does not sufficiently address this issue.
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')
DSGVO All in one for WP <= 4.2 carries this weakness at dsdvo_customimprinttext, and reaching it takes an account at Administrator level or above. 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 DSGVO All in one for WP the fix is 4.3: builds <= 4.2 are affected, anything from 4.3 onward is not.
Remediation
Update to version 4.3, or a newer patched version
How does WordSec protect against this?
An attacker needs Administrator 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: DSGVO All in one for WP 4.3 closes this, and updating the plugin is the step that ends it.
