VAR-202506-1063

Vulnerability from variot - Updated: 2025-07-04 23:50

A vulnerability was found in TOTOLINK N300RH 6.1c.1390_B20191101 and classified as critical. Affected by this issue is some unknown functionality of the file /boafrm/formPortFw of the component HTTP POST Message Handler. The manipulation of the argument service_type leads to buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. TOTOLINK of N300RH The firmware contains a buffer error vulnerability and 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 N300RH is a long-distance wireless router from China's TOTOLINK Electronics.

TOTOLINK N300RH has a buffer overflow vulnerability, which is caused by the parameter service_type in the file /boafrm/formPortFw failing to correctly verify the length of the input data. Attackers can exploit this vulnerability to execute arbitrary code on the system or cause a denial of service
