Vulnerability from variot - Updated: 2025-06-15 23:48An issue in TOTOLINK A3100R V4.1.2cu.5247_B20211129 allows a remote attacker to execute arbitrary code via the setWebWlanIdx of the file /lib/cste_modules/wireless.so. TOTOLINK of A3100R The firmware has OS A command injection vulnerability exists.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. TOTOLINK A3100R is a series of wireless routers from China's TOTOLINK Electronics.
TOTOLINK A3100R has a code execution vulnerability, which is caused by setWebWlanIdx failing to properly filter special characters and commands in constructing commands

VAR-202505-1004
Vulnerability from variot - Updated: 2025-06-01 23:18TOTOLINK A3100R V5.9c.1527 is vulnerable to Buffer Overflow via the priority parameter in the setMacQos interface of /lib/cste_modules/firewall.so. TOTOLINK of A3100R An out-of-bounds write vulnerability exists in firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. TOTOLINK A3100R is a series of wireless routers produced by China's TOTOLINK Electronics. The vulnerability is caused by the failure of the priority parameter of the setMacQos interface in /lib/cste_modules/firewall.so to correctly verify the length of the input data.

VAR-202407-2402
Vulnerability from variot - Updated: 2025-04-22 23:28A vulnerability was found in TOTOLINK A3100R 4.1.2cu.5050_B20200504. It has been classified as critical. This affects the function getSaveConfig of the file /cgi-bin/cstecgi.cgi?action=save&setting. The manipulation of the argument http_host leads to buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-272571. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. TOTOLINK of A3100R 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 A3100R is a series of wireless routers from China's TOTOLINK Electronics. The vulnerability is caused by the http_host of the getSaveConfig function of /cgi-bin/cstecgi.cgi?action=save&setting failing to correctly verify the length of the input data. A remote attacker can exploit this vulnerability to execute arbitrary code on the system or cause a denial of service attack
