Fortinet heeft kwetsbaarheden verholpen in FortiWeb. De eerste kwetsbaarheid betreft een Improper Authentication in meerdere versies van FortiWeb, waardoor een externe, niet-geauthenticeerde aanvaller toegang kan krijgen tot de GUI- en CLI-interfaces door het indienen van willekeurige inloggegevens. Deze kwetsbaarheid treedt ook op bij FortiWeb-systemen die zijn geconfigureerd met Remote Radius Type Admin Authentication onder bepaalde niet-standaard instellingen. Hierdoor kan een aanvaller de…
Fortinet heeft een kwetsbaarheid verholpen in FortiManager en FortiManager Cloud versies 7.2.5 tot en met 7.6.1. De kwetsbaarheid betreft een authenticatiebypass via een alternatieve route of kanaal. Een externe, niet-geauthenticeerde aanvaller die beschikt over een geldig certificaat kan zich voordoen als een FortiGate-apparaat dat wordt beheerd door FortiManager door speciaal opgemaakte FGFM-verzoeken te versturen. De oorzaak ligt in onjuiste toegangscontrolemechanismen binnen de getroffen…
Fortinet heeft een kwetsbaarheid verholpen in FortiClient voor Windows. De kwetsbaarheid betreft een klassieke buffer overflow in de verwerking van DNS response packets. Deze ontstaat door een buffer copy operatie zonder controle op de grootte van de input. Hierdoor kan een niet-geauthenticeerde aanvaller kwaadaardige DNS responses opstellen en versturen. Bij succesvolle exploitatie kan de aanvaller willekeurige code uitvoeren binnen de context van de FortiClient applicatie.
De multiples vulnérabilités ont été découvertes dans les produits Fortinet. Certaines d'entre elles permettent à un attaquant de provoquer une exécution de code arbitraire à distance, une élévation de privilèges et un déni de service à distance.
