A malicious actor could exploit this vulnerability by sending a specially crafted request that contains an excessively long &#8216;wanSpeed&#8217; value. This would cause a buffer overflow, allowing an attacker to execute arbitrary code or disrupt system operations.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-3750602228\" 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>The following is a hypothetical example of how the vulnerability might be exploited.

All users are strongly advised to update their Tenda AC18 firmware to the latest version as soon as possible. In the meantime, users might consider deploying a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure to detect and block attempted exploits of this vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The CVE-2025-60662 pertains to a critical security vulnerability identified in the Tenda AC18 V15.03.05.19.
