Vulnerability from variot - Updated: 2025-07-30 23:13

Tenda FH1203 v2.0.1.6 has a stack overflow vulnerability in the schedStartTime parameter of the setSchedWifi function. Shenzhen Tenda Technology Co.,Ltd. of fh1203 Firmware has a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The Tenda FH1203 is a dual-band wireless router released by China's Tenda, primarily used for home network coverage. This vulnerability stems from the failure of the schedStartTime parameter in the setSchedWifi method to properly validate the length of the input data. An attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service
