What it is about
Open Source Argo CD ist ein deklaratives, GitOps-basiertes Continuous-Delivery-Tool für Kubernetes. Ein Angreifer kann mehrere Schwachstellen in Argo CD ausnutzen, um beliebigen Programmcode auszuführen, vertrauliche Informationen und Zugangsdaten auszulesen, Zugriffsbeschränkungen zu umgehen oder einen Denial of Service zu verursachen.
Under what conditions?
The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.
What can happen in the worst case
An attacker could use the vulnerability to
- beliebigen Programmcode auszuführen
- vertrauliche Informationen
- Zugangsdaten auszulesen
- Zugriffsbeschränkungen zu umgehen oder einen Denial of Service zu verursachen
Am I affected?
Affected according to the BSI:
- Open Source Argo CD <3.3.15
- Open Source Argo CD <3.4.10
- Open Source Argo CD <3.5.4
- Open Source Argo CD <3.6.0-rc2
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source Argo CD 3.3.15
- Open Source Argo CD 3.4.10
- Open Source Argo CD 3.5.4
- Open Source Argo CD 3.6.0-rc2
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.
