This invalid request causes a divide by zero error. As this is an unexpected condition for the server, it can lead to a denial of service, leaving the server unavailable for legitimate users. In the worst-case scenario, this could potentially be used to compromise the system or leak data.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2499376401\" 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 exploit could look like the following HTTP request:<\/p>\n<pre><code class=\"\" data-line=\"\">POST \/vulnerable\/endpoint HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ &quot;invalid_request&quot;: &quot;divide_by_zero&quot; }<\/code><\/pre>\n<p>In this example, the attacker sends a POST request with an invalid request payload that causes a divide by zero error in the server.<\/p>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>Users are strongly recommended to apply the vendor patch as soon as possible. While waiting for the patch to be applied, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. These can help by blocking or alerting on any malicious requests that try to exploit this vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The vulnerability CVE-2025-23321 pertains to both Windows and Linux versions of the NVIDIA Triton Inference Server.
