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

CVE-2025-45429 is a severe and potentially damaging vulnerability found in the Tenda ac9 v1.0 router, specifically in the firmware version V15.03.05.14_multi. This particular vulnerability exposes a stack overflow situation in \/goform\/WifiWpsStart, which could potentially lead to remote arbitrary code execution by malicious actors.
\nThis vulnerability is notable as the Tenda ac9 v1.0<\/a> router is a widely-used piece of hardware in both personal and professional environments. The consequences of a successful exploit could be severe, ranging from system compromise to data<\/a> leakage, which could have a significant impact on both individuals and businesses alike.<\/p>\n

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

CVE ID: CVE-2025-45429
\nSeverity: Critical (9.8 CVSS Severity Score)
\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> router | 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 \/goform\/WifiWpsStart endpoint of the router’s firmware. A malicious actor could potentially send a specially crafted request to this endpoint, overflowing the stack and allowing them to execute arbitrary code<\/a> remotely. This could lead to a complete system compromise, giving the attacker unrestricted access to the system and potentially leading to data<\/a> leakage.<\/p>\n

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

The following is a conceptual example of how the vulnerability might be exploited. This is a sample HTTP request that could be used to overflow the stack and execute arbitrary code<\/a>:<\/p>\n

POST \/goform\/WifiWpsStart HTTP\/1.1\nHost: target_router_ip\nContent-Type: application\/json\n{ \"malicious_payload\": \"A\"*1024 }  \/\/ Stack overflow with 1024 'A' characters<\/code><\/pre>\n
Please note that this is only a conceptual example and actual payloads may vary. Nonetheless, the result of such an attack could be significant, leading to a system compromise or potential<\/a> data leakage. It is therefore highly recommended that users of the affected product apply the vendor patch immediately or use a Web<\/a> Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation.<\/p>\n","protected":false},"excerpt":{"rendered":"
