Detection Guidance

This vulnerability involves stored cross-site scripting (XSS) through the title parameter in the Slider by Soliloquy WordPress plugin version 2.6.2 or earlier. Detection involves checking for malicious JavaScript payloads injected into slider titles.

To detect this on your system, you can review the slider titles in the WordPress admin interface for suspicious JavaScript code or unusual script tags.

Additionally, you can search the WordPress database directly for suspicious content in the slider titles. For example, using a MySQL command to find script tags in the slider titles:

• SELECT * FROM wp_soliloquy_sliders WHERE title LIKE '%<script>%';

You may also monitor HTTP traffic for suspicious script execution or injection attempts when authenticated users create or edit sliders.

Mitigation Strategies

The immediate mitigation step is to update the Slider by Soliloquy plugin to a version later than 2.6.2 where this stored XSS vulnerability is fixed.

If an update is not immediately possible, restrict slider creation and editing permissions to trusted users only, as the vulnerability requires authenticated access.

Additionally, review and sanitize existing slider titles to remove any injected malicious scripts.

Implement web application firewall (WAF) rules to detect and block suspicious script injection attempts targeting the title parameter.
