Summary
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.
