Feiten: Ivanti heeft een kwetsbaarheid verholpen in Connect Secure.
Interpretaties: Een kwaadwillende kan de kwetsbaarheid misbruiken om zonder voorafgaande authenticatie willekeurige commando's uit te voeren op het kwetsbare systeem. Ivanti meldt op de hoogte te zijn van rapporten dat de kwetsbaarheid als ZeroDay kwetsbaarheid is misbruikt. Er is (nog) geen publieke Proof-of-Concept (PoC) beschikbaar, maar het NCSC verwacht dat publieke PoC of exploitcode op korte termijn beschikbaar komt, wat de kans op grootschalig misbruik vergroot.
Oplossingen: Ivanti heeft updates uitgebracht om de kwetsbaarheid te verhelpen. Zie bijgevoegde referenties voor meer informatie.
Kans: high
Schade: high
CWE-290: Authentication Bypass by Spoofing

An authentication bypass vulnerability in ICS versions before 25.1.3.0 allows remote unauthenticated attackers to execute arbitrary commands, while versions 22.7R2.14 and earlier remain unaffected.
