I WordPress-till\u00e4gget Ninja Forms, som har \u00f6ver en miljon aktiva installationer, har en kritisk s\u00e5rbarhet uppt\u00e4ckts (CVE har \u00e4nnu inte tilldelats), vilket g\u00f6r det m\u00f6jligt f\u00f6r obeh\u00f6riga bes\u00f6kare att f\u00e5 fullst\u00e4ndig kontroll \u00f6ver webbplatsen. Problemet har \u00e5tg\u00e4rdats i versionerna 3.0.34.2, 3.1.10, 3.2.28, 3.3.21.4, 3.4.34.2, 3.5.8.4 och 3.6.11. Det noteras att s\u00e5rbarheten redan utnyttjas f\u00f6r attacker, och f\u00f6r att akut l\u00e5sa problemet har utvecklarna av WordPress-plattformen initierat en tvingande automatisk installation av uppdateringen p\u00e5 anv\u00e4ndarnas webbplatser. <\/p>\n

S\u00e5rbarheten orsakas av ett fel i genomf\u00f6randet av Merge Tags-funktionaliteten, vilket g\u00f6r det m\u00f6jligt f\u00f6r icke-autentiserade anv\u00e4ndare att anropa vissa statiska metoder fr\u00e5n olika klasser i Ninja Forms (f\u00f6r att kontrollera referenserna till metoderna i de data som \u00f6verf\u00f6rs via Merge Tags kallades funktionen is_callable()). Bland annat var det m\u00f6jligt att anropa en metod som utf\u00f6r deserialisering av inneh\u00e5ll som skickas av anv\u00e4ndaren. Genom att \u00f6verf\u00f6ra s\u00e4rskilt formaterade serialiserade data kunde angriparen infoga sina egna objekt och f\u00e5 PHP-kod att k\u00f6ras p\u00e5 servern<\/a> eller ta bort godtyckliga filer fr\u00e5n webbplatsens datakatalog.
