WordPress Plugin SSL Insecure Content Fixer Full Path Disclosure Scanner

The WordPress Plugin SSL Insecure Content Fixer is used widely by administrators of WordPress sites to address issues with mixed content, which can occur when a site that is supposed to serve content securely inadvertently includes non-secure content. This plugin is essential for ensuring that all elements of a site are served over HTTPS, thus maintaining user trust and improving search engine rankings. It is typically utilized by developers and site owners who want to quickly fix SSL-related issues without delving into the code themselves. Many websites with SSL certificates and security-conscious management rely on this plugin for optimal site performance and security. The plugin's straightforward interface makes it accessible even for users who are not technically inclined, increasing its utility across a broad range of WordPress sites.

Full Path Disclosure (FPD) is a vulnerability that allows an attacker to see the full path of the webroot directory of a server. While seemingly minor, this information can be leveraged by attackers to launch further attacks by understanding the server's directory structure. In the context of web applications like WordPress, this can expose sensitive information that might aid in further exploits. The WordPress Plugin SSL Insecure Content Fixer exposes such vulnerabilities when its files are accessed directly, lacking proper ABSPATH protection. Exploiting this vulnerability, harmful agents can potentially create strategies for attacks based on the disclosed paths. Hence, it is critical for this plugin to enforce access restrictions robustly.

The directories within the WordPress Plugin SSL Insecure Content Fixer, specifically '/wp-content/plugins/ssl-insecure-content-fixer/includes/nonces.php' and '/wp-content/plugins/ssl-insecure-content-fixer/nowp/ajax.php', can be directly accessed. Access to these files without ABSPATH protection results in PHP error messages disclosing sensitive server path details. Conditions such as the presence of error messages like "Fatal error" or "Uncaught Error," confirm the vulnerability. Furthermore, the exposure can be verified when the server returns statuses such as 200 or 500 in response to requests. Such negligence in managing access controls compromises the plugin's security posture, inviting potential misuse of the disclosed information.

When exploited, this vulnerability could result in a leaked directory structure, providing attackers with knowledge necessary to craft more sophisticated cyber-attacks. Knowing the precise location of specific files can aid attackers in locating additional vulnerabilities, launching targeted exploits, or creating strategies for malware deployment. Additionally, it can lead to unauthorized access or manipulation of plugin files, leading to data loss or corruption. Ultimately, this undermines the security of the entire WordPress site where the plugin is installed, negatively affecting both site integrity and user trust.
