A stack-based buffer overflow in the httpd server on Tenda AC9 V15.03.06.60_EN allows remote attackers to execute arbitrary code or cause a denial of service (DoS) via a crafted POST request to /goform/SetStaticRouteCfg. Un desbordamiento de búfer en la región stack de la memoria en el servidor httpd en Tenda AC9 versión V15.03.06.60_ES, permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (DoS) por medio de una petición POST diseñada a /goform/SetStaticRouteCfg • https://cwe.mitre.org/data/definitions/121.html https://github.com/grapefruitvul/vulinfo/blob/master/tenda/vul1.md • CWE-787: Out-of-bounds Write •

An issue was discovered on Tenda AC6 V1.0 V15.03.05.19_multi_TD01, AC9 V1.0 V15.03.05.19(6318)_CN, AC9 V3.0 V15.03.06.42_multi, AC15 V1.0 V15.03.05.19_multi_TD01, and AC18 V15.03.05.19(6318_)_CN devices. There is a buffer overflow vulnerability in the router's web server -- httpd. While processing the /goform/openSchedWifi schedStartTime and schedEndTime parameters for a POST request, a value is directly used in a strcpy to a local variable placed on the stack, which overwrites the return address of a function. An attacker can construct a payload to carry out arbitrary code execution attacks.
