A security flaw has been discovered in Ruijie EG105G-P 2.340. The impacted element is the function nslookup of the file /cgi-bin/luci/api/diagnose of the component JSON-RPC Diagnose Endpoint. Performing a manipulation of the argument params.target results in command injection. It is possible to initiate the attack remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
Weakness
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
