CVE-2024-57537Public exploit

Memory corruption via unchecked page field copy

Published Jan 21, 2025 · Updated Jan 22, 2025

Stack buffer overflow in Linksys E8450 1.2.00.360516 allows remote attackers on an adjacent network to corrupt memory via portal.cgi. The sub_422eb8 JSON parser passes the attacker-controlled page field to strncpy without verifying that it fits in the destination stack buffer. No authentication is required, and the published proof of concept establishes memory corruption but does not demonstrate code execution or a specific service interruption.
