An attacker with local access and low privileges can <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-6939-critical-buffer-overflow-vulnerability-in-totolink-a3002ru\/\"  data-wpil-monitor-id=\"92395\">overflow the stack buffer<\/a> by sending specially crafted input that exceeds the buffer&#8217;s boundary. This condition allows the attacker to overwrite the intended data structure, potentially leading to arbitrary <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-2945-critical-remote-code-execution-vulnerability-in-pgadmin-4\/\"  data-wpil-monitor-id=\"92525\">code execution<\/a> with the same privileges as the user running the affected software.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2383979254\" 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 using a shell command:<\/p>\n<pre><code class=\"\" data-line=\"\">$ echo -e &#039;GET \/vulnerable\/path HTTP\/1.1\\r\\nHost: www.target.com\\r\\n\\r\\n&#039; | nc target.com 80<\/code><\/pre>\n<p>In this example, the command sends a GET request with an excessively long string to the <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-52811-path-traversal-vulnerability-in-davenport-wordpress-theme\/\"  data-wpil-monitor-id=\"92379\">vulnerable path<\/a> on the target host. If the string is processed by the vulnerable software and exceeds the stack buffer&#8217;s boundary, it could lead to a <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-6940-critical-buffer-overflow-vulnerability-in-totolink-a702r\/\"  data-wpil-monitor-id=\"92398\">buffer overflow<\/a>, resulting in arbitrary code execution.<\/p>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>To protect against this vulnerability, it&#8217;s recommended to apply the latest vendor-provided patch for Windows NTFS. If a patch is not immediately available or applicable, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by identifying and blocking attempts to exploit this vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview CVE-2025-54916 is a high-risk vulnerability that affects Windows NTFS.
