WordPress All Export Cross-Site Scripting Scanner

WordPress All Export is a widely used plugin for exporting data from WordPress sites. It is popular among site administrators and developers for its flexibility in exporting posts, pages, custom post types, and more. This plugin simplifies data transfer processes, enabling easier migration and data handling between different WordPress sites. Due to its extensive capabilities, it is used in many industries where data portability is crucial. The All Export plugin allows for custom export rules and seamless file format handling, meeting the varied needs of its users. WordPress All Export supports export to multiple file formats, making it highly versatile and adaptable.

The Cross-Site Scripting (XSS) vulnerability occurs when the application does not properly sanitize user inputs or output. In the case of WordPress All Export, some URLs were not escaped properly before being output in attributes, leading to this vulnerability. XSS vulnerabilities can allow attackers to inject malicious scripts into webpages viewed by other users. When exploited, these malicious scripts can execute arbitrary code in the context of the user's session. This type of vulnerability is commonly exploited in phishing attacks or to spread malware. The vulnerability affected plugin versions before 1.3.6.

Technical details of this vulnerability involve improper escaping of URLs within the plugin's interface. The vulnerable parameter resides in the admin panel, particularly in URLs output in page attributes. Attackers can craft URLs with embedded scripts that execute when accessed by unsuspecting users. The vulnerable endpoint typically involves the administration panel where encoded scripts can be inputted. It requires authentication, as seen in the HTTP requests with login attempts. Successful exploitation results in reflected XSS vulnerabilities manifesting in the browser of authenticated users.

When exploited, the vulnerability can lead to potential account compromise or unauthorized actions within the WordPress instance. Attackers can execute arbitrary scripts in the victim's browser context, leading to stolen cookies or session identifiers. This can allow the attacker to impersonate legitimate users, potentially accessing their sensitive data. Phishing attacks become more plausible due to injected scripts redirecting or mimicking legitimate interfaces. Malware could be distributed through these means, further compromising system integrity. The XSS vulnerability can undermine user trust and affect the site's credibility significantly.
