This flaw enables a local attacker to execute arbitrary code with elevated system privileges. The vulnerability is triggered via a crafted payload pasted into the \u0026ldquo;Name\u0026rdquo; and \u0026ldquo;Code\u0026rdquo; fields within the \u0026ldquo;Help \u0026gt; Register\u0026rdquo; dialog. Successful exploitation leads to a reverse shell with system privileges, posing a significant risk to affected systems.
