Overview<\/strong><\/p>\n

The CVE-2025-60662 pertains to a critical security vulnerability identified in the Tenda AC18 V15.03.05.19. This vulnerability, specifically a stack overflow, is potentially exploitable by malicious actors to compromise the system or leak sensitive data. Being a prevalent device in many network infrastructures, this vulnerability could have widespread implications if left unpatched.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-60662
\nSeverity: High (7.5 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: The successful exploit could lead to system compromise and data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Tenda AC18 | V15.03.05.19<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability arises from a stack overflow in the ‘fromAdvSetMacMtuWan’ function, where the ‘wanSpeed’ parameter is mishandled. A malicious actor could exploit this vulnerability by sending a specially crafted request that contains an excessively long ‘wanSpeed’ value. This would cause a buffer overflow, allowing an attacker to execute arbitrary code or disrupt system operations.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

The following is a hypothetical example of how the vulnerability might be exploited. This is a sample HTTP request that sends a malicious payload to trigger the stack overflow.<\/p>\n

POST \/fromAdvSetMacMtuWan HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\nwanSpeed=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA... [continue until buffer overflow]<\/code><\/pre>\n
Please note that this is a conceptual example and does not represent actual exploit code.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
Tenda has released a patch to fix this vulnerability. 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":"
