The vulnerability arises when the function attempts to access memory that has not been properly initialized or that has been deleted. This causes the program to behave unpredictably, leading to segmentation faults and causing the program to crash.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2017527405\" 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>A potential example of how this vulnerability might be exploited could be an attacker sending an improperly formatted data packet to the c-ray software. This could be illustrated as follows:<\/p>\n<pre><code class=\"\" data-line=\"\">POST \/c-ray\/process_data HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ &quot;malformed_data&quot;: &quot;...&quot; }<\/code><\/pre>\n<p>Where &#8220;malformed_data&#8221; contains the payload that causes the Null Pointer Dereference, triggering the vulnerability. The exact nature of the payload would depend on the specific implementation of the parse_mtllib function within the c-ray 1.1 software.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The CVE-2025-45332 vulnerability pertains to a Null Pointer Dereference (NPD) in vkoskiv c-ray 1.1.
