| Title | Shenzhen Tenda Technology Co.,Ltd. AC21 <= V16.03.08.16 Buffer Overflow |
|---|
| Description | A buffer overflow vulnerability was discovered on the latest version of the Tengda AC21 router, V16.03.08.16, where an attacker sent a well-crafted http post packet to the request path /goform/SetStaticRouteCfg, triggering a denial of service attack or even RCE, specifically via the function sscanf(s_5, "%[^,],%[^,],%[^,],%s", v15, v16, v17, v18) because there is no bounds check on s_5, causing a stack overflow |
