Critical Vulnerability in NestJS Devtools: Localhost RCE via Sandbox Escape
A flawed sandbox in @nestjs/devtools-integration lets attackers run code on your machine via CSRF, leading to full Remote Code Execution (RCE).
A simple UDP server library using working queue.
> gem install udpbucket
>
UDPBucket returns to a block each packet it receives to the listening UDP port formatted in a standard hash.
{ :client_sock => <socket_object>,
:client_ip => 'x.x.x.x',
:client_port => xxxxx,
:payload => '\x00\xFF\xFF' }
require 'udpbucket'
begin
cfg = { :localhost => '0.0.0.0', :localport => 1024, :debug => 0 }
udpbucket = UDPBucket::Core.new cfg
udpbucket.listen do |req|
if req[:payload] == '\x00\xFF\xFF'
req[:client_sock].send '<..some payload..>', 0, req[:client_ip], req[:client_port]
udpbucket.debug "reply sent to client: #{req[:client_ip]}:#{req[:client_port]}" if cfg[:debug] == 1
end
end
end
The configuration is loaded at the start via Asetus. If the configuration is not passed to the 'Core' class, Asetus will load the default set (localhost:'0.0.0.0',localport:'16265',debug:'0')
