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

The Common Vulnerabilities and Exposures (CVE) system has recently identified a critical vulnerability, CVE-2025-45428, found in Tenda AC9 v1.0 with firmware V15.03.05.14_multi. This vulnerability could potentially allow a remote attacker to execute arbitrary code on the affected system, leading to a full-scale compromise of the system and potential data leakage. As Tenda AC9 routers are widely used, this vulnerability could pose a significant risk to countless networks and systems worldwide, making the understanding and mitigation of this vulnerability crucial for maintaining cybersecurity<\/a> standards.<\/p>\n

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

CVE ID: CVE-2025-45428
\nSeverity: Critical (CVSS score 9.8)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise and potential<\/a> data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Tenda AC9 v1.0<\/a> | Firmware V15.03.05.14_multi<\/p>\n

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

The exploit takes advantage of a stack overflow vulnerability<\/a> in the rebootTime parameter of the \/goform\/SetSysAutoRebbotCfg endpoint in the Tenda AC9 firmware. A remote attacker can send a specially crafted request to this endpoint, causing the stack overflow, which in turn allows the execution of arbitrary code<\/a>. The attacker does not need any special privileges to exploit this vulnerability<\/a>, and no user interaction is required, which makes this vulnerability particularly dangerous.<\/p>\n

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

Here is a conceptual example of how a malicious HTTP request exploiting this vulnerability<\/a> might look:<\/p>\n

POST \/goform\/SetSysAutoRebbotCfg HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"rebootTime\": \"[malicious_payload]\" }<\/code><\/pre>\n
In the above example, “[malicious_payload] represents a string of code designed to cause a stack overflow and execute arbitrary code on the system<\/a>.<\/p>\n
Recommended Mitigation<\/strong><\/p>\n
Users of the affected Tenda AC9<\/a> firmware are strongly advised to apply the vendor patch as soon as it becomes available. In the meantime, utilizing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation for this vulnerability. Regularly updating systems and software, and monitoring network traffic for any suspicious activity are general best practices that can also help protect against such vulnerabilities<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
