Authenticated memory corruption via pppoeUser overflow
Published Nov 23, 2022 · Updated Apr 25, 2025
Out-of-bounds write in TOTOLINK LR350 9.3.5u.6369_B20220309 allows remote authenticated users to corrupt memory via pppoeUser. Public records identify setOpModeCfg and pppoeUser but do not disclose the unsafe copy operation or destination buffer size. Access to the authenticated management interface is required; the record does not establish whether the corruption produces a crash or code execution.
