Authenticated memory corruption via DNS list rendering
Published Jul 13, 2026 · Updated Jul 13, 2026
Stack-based buffer overflow in Shibby Tomato 1.0 through 1.28.0000 allows remote authenticated users to corrupt httpd memory. In the DNS List Rendering path, sub_407220 in /usr/sbin/httpd writes beyond a stack buffer, although the published report does not identify the triggering field or copy operation. Low-privileged network access is required; successful corruption can compromise the router process, while an unsuccessful attempt can crash it.
