Detection Guidance

This vulnerability can be detected by checking for the presence of malicious JavaScript payloads injected into the 'icon title' field of the AccessPress Social Icons plugin interface. Since the vulnerability is a stored cross-site scripting (XSS), detection involves inspecting the plugin's stored data for suspicious script tags or event handlers such as 'onerror' in image tags.

Commands or methods to detect this vulnerability include:

• Using web application scanning tools to crawl the plugin pages and look for reflected or stored XSS payloads.
• Manually inspecting the database entries related to the plugin's 'icon title' field for suspicious JavaScript code.

• Restrict access to the plugin interface to trusted authenticated users only, minimizing the risk of attackers injecting malicious scripts.
• Remove or sanitize any suspicious or malicious entries in the 'icon title' field within the plugin settings or database.
• Disable or uninstall the AccessPress Social Icons plugin, especially since it was removed from the WordPress Plugin Directory and is no longer maintained.
