TITLE

TOTOLINK of A3002RU Classic buffer overflow vulnerability in firmware

Trust: 0.8

sources: JVNDB: JVNDB-2024-025694

DESCRIPTION

TOTOLINK AC1200 Wireless Router A3002RU V2.1.1-B20230720.1011 is vulnerable to Buffer Overflow. The formWlEncrypt CGI handler in the boa program fails to limit the length of the wlan_ssid field from user input. This allows attackers to craft malicious HTTP requests by supplying an excessively long value for the wlan_ssid field, leading to a stack overflow. This can be further exploited to execute arbitrary commands or launch denial-of-service attacks. TOTOLINK of A3002RU 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. TOTOLINK AC1200 is a dual-band Wi-Fi router from China's TOTOLINK Electronics
