The software does not correctly handle memory allocation for certain user-supplied input. An attacker who successfully exploits this <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-2945-critical-remote-code-execution-vulnerability-in-pgadmin-4\/\"  data-wpil-monitor-id=\"92496\">vulnerability could execute arbitrary code<\/a> in the context of the current user, leading to unauthorized system access, data manipulation, or even system compromise. Exploitation requires user interaction, specifically the opening of a malicious file.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2890729826\" 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>While the exact code to exploit this vulnerability would depend on many factors, a conceptual example might look like this:<\/p>\n<pre><code class=\"\" data-line=\"\"># pseudo code for the exploit\nclass MaliciousFile:\ndef __init__(self, payload):\nself.payload = payload\ndef open_file(self, application):\napplication.memory_free(self)\napplication.execute_code(self.payload)\n# attacker creates a malicious file\nmalicious_file = MaliciousFile(&quot;arbitrary code&quot;)\n# victim opens the malicious file using Substance3D Modeler\nmalicious_file.open_file(Substance3D_Modeler)<\/code><\/pre>\n<p>In this pseudo code, the `MaliciousFile` class represents the malicious file created by the attacker. The `open_file` method mimics the process of opening the file with Substance3D &#8211; Modeler. The use-after-free vulnerability is exploited when the application frees up the memory associated with the malicious file and then executes the arbitrary code contained in the payload.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview This report provides a detailed analysis of the CVE-2025-54258 vulnerability that affects Substance3D &#8211; Modeler versions 1.22.2 and earlier.
