Vulnerability Details : CVE-2023-27361
NETGEAR RAX30 rex_cgi JSON Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR RAX30 routers. Authentication is required to exploit this vulnerability.
The specific flaw exists within the handling of JSON data. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer.
