A buffer overflow vulnerability exists in the setParentalRules interface of TOTOLINK A950RG V4.1.2cu.5204_B20210112. The urlKeyword parameter is not properly validated, and the function concatenates multiple user-controlled fields into a fixed-size stack buffer without performing boundary checks. A remote attacker can exploit this flaw to cause denial of service or potentially achieve arbitrary code execution.

Totolink AC1200 Wireless Dual Band Gigabit Router A3002RU_V3 Firmware V3.0.0-B20230809.1615 is vulnerable to Buffer Overflow. The "boa" program allows attackers to modify the value of the "vwlan_idx" field via "formMultiAP". This can lead to a stack overflow through the "formWlEncrypt" CGI function by constructing malicious HTTP requests and passing a WLAN SSID value exceeding the expected length, potentially resulting in command execution or denial of service attacks.
