🚨 Upozorňujeme na kritickou zranitelnost "OVERPASS" v SAP Extended Passport (EPP) Processing, CVE-2026-44756. Jedná se o zranitelnost typu poškození paměti s hodnocením CVSS 10, která se nachází v systémovém jádře SAP při zpracování Extended Passport (EPP) dat. Příčinou je chybějící validace hranic během deserializace EPP dat, což vede k narušení bezpečnosti paměti při zpracování externě dodaných délkových polí. Neautentizovaný vzdálený útočník může zaslat speciálně vytvořený požadavek s malformovanou EPP hlavičkou a vyvolat neočekávané chování, pád procesu a následně vzdálené spuštění libovolných příkazů operačního systému s administrátorskými oprávněními SAP. Zranitelnost je zneužitelná bez přihlášení a je dosažitelná přes internetově dostupnou webovou vrstvu, SAP GUI i RFC komunikaci. Úspěšné zneužití může vést k úplnému kompromitování systému, získání přihlašovacích údajů k databázi, hashů hesel, přístupu k obchodním datům, relacím přihlášených uživatelů, laterálnímu pohybu do dalších SAP systémů a modifikaci aplikačních dat, konfigurace i binárních souborů SAP. 📌Doporučujeme aktualizovat na nejnovější verzi.
