If manipulated, an attacker can induce a buffer overflow via cloneType2, which could allow arbitrary code execution or cause the system to crash. The attack can be initiated remotely over a network, without any user interaction, and requires only low-level privileges to execute.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-3206540965\" 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:<\/p>\n<pre><code class=\"\" data-line=\"\">POST \/AdvSetMacMtuWan HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\ncloneType2={ &quot;malicious_payload&quot;: &quot;AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA...&quot;}<\/code><\/pre>\n<p>In the above example, the attacker sends an excessively long string in the &#8220;malicious_payload&#8221;, causing a buffer overflow in the AdvSetMacMtuWan function.<br \/>\nIt&#8217;s recommended that all users apply the patch provided by the vendor as soon as possible or use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure until the patch can be applied.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview This report covers the details of CVE-2025-25457, a severe buffer overflow vulnerability found in Tenda AC10 V4.0si_V16.03.10.20.
