CVE-2022-40047 Scanner

Flatpress is a lightweight, easy-to-use blogging platform that does not require a database. It's designed for simplicity and ease of use, making it an ideal choice for individuals and small organizations looking to publish content online without the complexity of database management. Flatpress supports a wide range of plugins and themes, allowing users to customize their blogs according to their preferences. However, versions prior to v1.2.1 have been found to be vulnerable to cross-site scripting attacks, posing a security risk to users and visitors.

The vulnerability in question is a reflected Cross-Site Scripting (XSS) issue that exists due to improper sanitization of user-supplied data in the 'page' parameter on the 'admin.php' page. This flaw allows attackers to execute arbitrary HTML and script code in a user's browser session in the context of the affected site. Such vulnerabilities are exploited by crafting malicious URLs that, when visited by an unsuspecting user, can lead to unauthorized actions being performed, data theft, and potentially gaining control over the user's session.

Specifically, the XSS vulnerability in Flatpress before v1.2.1 allows attackers to inject malicious JavaScript code through the 'page' parameter in the 'admin.php' file. This can be exploited by an attacker by sending a specially crafted link to the admin of the site or embedding the link in another webpage. If the admin clicks on the link or interacts with the malicious page, the injected script is executed, potentially compromising the admin's session or performing unauthorized actions on the admin's behalf.

Exploitation of this XSS vulnerability can lead to several adverse effects, including session hijacking, redirection to malicious sites, unauthorized actions on behalf of the admin, and theft of sensitive information. Since the attack is executed in the context of the user's session, it can bypass some security measures and give attackers access to restricted areas of the site or sensitive data.
