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

This report covers the details of CVE-2025-25457, a severe buffer overflow vulnerability found in Tenda AC10 V4.0si_V16.03.10.20. The vulnerability affects users of this product and could potentially lead to system compromise or data leakage if exploited. The severity of the vulnerability and its wide potential impact make it a critical issue that requires immediate attention.<\/p>\n

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

CVE ID: CVE-2025-25457
\nSeverity: High (7.5 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: None
\nImpact: System compromise and potential data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Tenda AC10 | V4.0si_V16.03.10.20<\/p>\n

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

The vulnerability resides in the AdvSetMacMtuWan function of the Tenda AC10 firmware. 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

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

Below is a conceptual example of how the vulnerability might be exploited:<\/p>\n

POST \/AdvSetMacMtuWan HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\ncloneType2={ \"malicious_payload\": \"AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA...\"}<\/code><\/pre>\n
In the above example, the attacker sends an excessively long string in the “malicious_payload”, causing a buffer overflow in the AdvSetMacMtuWan function.
\nIt’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":"
