CVE-2024-7313 Scanner

The Shield Security Plugin is a popular security add-on used by WordPress administrators to protect their websites from various threats. Developed to enhance the overall security posture of WordPress sites, it offers features such as firewall protections, login security, and activity monitoring. Used widely within the WordPress community, the plugin helps non-technical users maintain robust security. The vulnerability checked software is essential for managing website security settings through a user-friendly interface. It is widely trusted by WordPress users to defend against potential attacks. This plugin’s continuous updates ensure it adapts to the latest security challenges.

The vulnerability in question is a Cross-Site Scripting (XSS) flaw found in the Shield Security Plugin before version 20.0.6. This reflected XSS vulnerability allows attackers to inject malicious scripts into a website, which get executed in the context of other authenticated administrators. Such vulnerabilities typically occur when input is improperly sanitized before being used in web applications. This specific flaw lies within the admin dashboard of the plugin, potentially allowing unauthorized actions by malicious actors. Such vulnerabilities are critical in the context of admin security as they can lead to the execution of unauthorized commands.

Technical details reveal that the XSS vulnerability in Shield Security Plugin involves the 'nav_sub' parameter on the admin dashboard. When the plugin does not properly sanitize and escape this parameter, it allows authenticated users to execute arbitrary JavaScript. The vulnerability is present within fetched URLs containing this parameter, which is then executed in the context of admin users. This could theoretically allow the attacker to hijack session cookies or execute unwanted commands. The crucial part here is that the script is executed after being injected into admin restricted pages, thereby leveraging authenticated user rights. Careful filtering and validation of parameters can mitigate this risk.

If exploited, the Cross-Site Scripting vulnerability could have numerous potential effects. Administrators might face unauthorized changes to their websites due to malicious script injection. Confidential information could be disclosed, leading to data breaches. Attackers might gain control over admin functionalities on the site. There’s also a possibility of redirecting users to malicious sites, thereby affecting the trustworthiness of the site. Additionally, such a breach could result in defamation or brand damage as well as GDPR violations if user data is involved.
