This occurs when an application exposes a reference to an internal implementation object, such as a file or database key. In the case of CVE-2025-51628, the &#8216;DocumentoId&#8217; parameter in the PdfHandler component is improperly validated, allowing attackers to manipulate references and gain unauthorized access to confidential documents.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-1097729103\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Here&#8217;s a hypothetical example of how an attacker might exploit this vulnerability. The attacker sends a malicious HTTP request, manipulating the &#8216;DocumentoId&#8217; parameter to access confidential documents:<\/p>\n<pre><code class=\"\" data-line=\"\">GET \/PdfHandler?DocumentoId=123456 HTTP\/1.1\nHost: target.example.com<\/code><\/pre>\n<p>In this example, &#8216;123456&#8217; represents the ID of the document the attacker wants to access. The server would then send the requested document without validating the user&#8217;s access rights, leading to a confidentiality breach.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview A critical vulnerability designated as CVE-2025-51628 has been identified in Agenzia Impresa Eccobook v2.81.1 and below.
