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

A serious vulnerability, CVE-2025-57528, has been discovered in Tenda AC6 US_AC6V1.0BR_V15.03.05.16_multi_TD01. This vulnerability can allow attackers to cause a denial of service to the system, potentially leading to system compromise or data leakage. This issue poses a significant threat to the integrity and availability of systems running the affected software.<\/p>\n

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

CVE ID: CVE-2025-57528
\nSeverity: High (CVSS: 7.7)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise, data leakage, and denial of service<\/p>\n

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

Product | Affected Versions<\/p>\n

Tenda AC6 | US_AC6V1.0BR_V15.03.05.16_multi_TD01<\/p>\n

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

The vulnerability lies in the formSetCfm function of the Tenda AC6 router software. The function improperly handles input given via the funcname, funcpara1, and funcpara2 parameters. If an attacker can manipulate these parameters with malicious input, they can cause a denial of service to the system.<\/p>\n

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

The conceptual example below demonstrates how an attacker might exploit this vulnerability using an HTTP request:<\/p>\n

POST \/SetCfm HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\nfuncname=&funcpara1=&funcpara2=<\/code><\/pre>\n
In this example, `` would be replaced with the attacker’s crafted data designed to exploit the vulnerability and cause a denial of service.<\/p>\n
Mitigation<\/strong><\/p>\n
Users are urged to apply the vendor patch as soon as possible to mitigate this vulnerability. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary protection.<\/p>\n","protected":false},"excerpt":{"rendered":"
