An attacker can craft a malicious PUT request that can overwrite files in the system. This can potentially lead to system compromise if critical system files are overwritten, or to data leakage if data files are overwritten with attacker-controlled data.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-3564041744\" 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>Below is a conceptual example of how the vulnerability might be exploited. This example demonstrates a malicious HTTP PUT request sent to the vulnerable endpoint.<\/p>\n<pre><code class=\"\" data-line=\"\">PUT \/vulnerable\/endpoint HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ &quot;file_path&quot;: &quot;\/critical\/system\/file&quot;, &quot;content&quot;: &quot;malicious_content&quot; }<\/code><\/pre>\n<p>In this example, the PUT request targets a critical system file for overwrite, replacing its content with malicious data.<\/p>\n<p><strong>Mitigation<\/strong><\/p>\n<p>Users are advised to apply the latest patch from the vendor as soon as possible. As a temporary mitigation, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to block or alert on malicious PUT requests. However, these measures do not remove the vulnerability but merely reduce the risk of exploitation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview This report presents a detailed analysis of the CVE-2025-45586 vulnerability, a critical flaw in Audi&#8217;s UTR 2.0 Universal Traffic Recorder.
