Vulnerability from cvelistv5 – Published: 2018-10-27 22:00 – Updated: 2024-08-05 11:16

Summary

An issue was discovered on Tenda AC7 V15.03.06.44_CN, AC9 V15.03.05.19(6318)_CN, AC10 V15.03.06.23_CN, AC15 V15.03.05.19_CN, and AC18 V15.03.05.19(6318)_CN devices. It is a buffer overflow vulnerability in the router's web server -- httpd.
