CVE-2023-29178Network attack vector

Authenticated httpsd crash via uninitialized pointer

Published Jun 13, 2023 · Updated Oct 22, 2024

Access of an uninitialized pointer in Fortinet FortiOS and FortiProxy allows remote authenticated users to crash httpsd with crafted requests. The httpsd request handler accesses an uninitialized pointer while processing a crafted vdom parameter. Valid credentials and network access to the HTTP or HTTPS management service are required, and repeated requests interrupt only that service.
