🚨 Upozorňujeme na zranitelnost v FortiSandbox, CVE-2026-59835. Zranitelnost s CVSS skóre 7.7 spočívá v neoprávněném zpřístupnění služby Virtual Network Computing (VNC) na všech síťových rozhraních v produktech FortiSandbox verzí 5.0 a 4.4. Neautentizovaný útočník může za předpokladu síťové dostupnosti této služby získat neoprávněný přístup k sandboxovým relacím, což může vést k narušení důvěrnosti a bezpečnosti analyzovaného prostředí. 📌Doporučujeme aktualizovat na verzi 5.0.3 či novější, případně 4.4.9 či novější.
Post summary
FortiSandbox CVE-2026-59835 allows unauthenticated VNC access with CVSS 7.7; the advisory urges users to upgrade to >=5.0.3 or 4.4.9 to mitigate the risk.
