What it is about
Google Cloud Platform (GCP) ist eine Sammlung von Cloud-Computing-Diensten von Google, die Infrastruktur, Datenanalyse, maschinelles Lernen und Entwicklungstools bietet. Unternehmen können dadurch Anwendungen in der Cloud zu aufbauen und skalierbar bereitzustellen. Ein entfernter, anonymer oder authentisierter Angreifer kann mehrere Schwachstellen in Google Cloud Platform ausnutzen, um einen Denial of Service Angriff durchzuführen.
Under what conditions?
Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.
What can happen in the worst case
An attacker could use the vulnerability to
- einen Denial of Service Angriff durchzuführen
Am I affected?
Affected according to the BSI:
- Amazon Linux 2
- Google Cloud Platform Service Mesh <1.27.2-asm.1
- Google Cloud Platform Service Mesh <1.26.5-asm.1
- Google Cloud Platform Service Mesh <1.25.5-asm.9
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Google Cloud Platform Service Mesh 1.27.2-asm.1
- Google Cloud Platform Service Mesh 1.26.5-asm.1
- Google Cloud Platform Service Mesh 1.25.5-asm.9
Is the vulnerability already being exploited?
None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
