CVE-2024-7465Network attack vector

Memory corruption via oversized http_host value

Published Aug 5, 2024 · Updated Aug 5, 2024

Buffer overflow in TOTOLINK CP450 4.1.0cu.747_B20191224 allows remote authenticated users to corrupt memory via a crafted HTTP request. The loginauth function in /cgi-bin/cstecgi.cgi processes an oversized http_host request-body value without a sufficient bounds check, overflowing its destination buffer. Low privileges and network access to the management interface are required; the published record does not specify whether exploitation causes a crash or code execution.
