CVE-2024-44390

Memory corruption via formWrlsafeset stack overflow

Published Aug 23, 2024 · Updated Aug 23, 2024

Stack-based buffer overflow in Tenda FH1206 1.2.0.8(8155)_EN allows attackers to corrupt memory through formWrlsafeset. The public record identifies formWrlsafeset as the faulty locus but does not disclose the request parameter, copy operation, or missing bounds check. Reachability is limited to the adjacent network, and public evidence does not establish whether exploitation ends in a crash or code execution.
