CVE-2025-9384Public exploit

Local tcprewrite crash via malformed port mapping

Published Aug 24, 2025 · Updated Aug 25, 2025

Null pointer dereference in AppNeta Tcpreplay 4.5.0 through 4.5.1 allows local users to crash tcprewrite via a malformed port map. In ports2PORT, malformed --portmap input leaves a pointer null and passes it to strtol during tcpedit_post_args processing. The user must execute tcprewrite locally with the crafted argument and a packet-capture input; exploitation terminates that process without reported data disclosure or modification.
