Memory corruption via unchecked traceroute command formatting
Published Aug 22, 2024 · Updated Aug 23, 2024
Buffer overflow in TOTOLINK T8 firmware 4.1.5cu.862_B20230228 allows remote authenticated users to corrupt memory through traceroute settings. The setTracerouteCfg handler uses sprintf to place an attacker-influenced traceroute command into a 128-byte array without checking its length. Access to the management request is required, and public material does not demonstrate whether corruption ends in a crash or attacker-controlled execution.
