What it is about
OpenSSH ist eine Open Source Implementierung des Secure Shell Protokolls. Ein Angreifer kann mehrere Schwachstellen in OpenSSH ausnutzen, um einen nicht näher spezifizierten Angriff durchzuführen, um einen Denial of Service Angriff durchzuführen, um Informationen offenzulegen, um Dateien zu manipulieren, und um Sicherheitsvorkehrungen zu umgehen.
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
- einen nicht näher spezifizierten Angriff durchzuführen
- einen Denial of Service Angriff durchzuführen
- Informationen offenzulegen
- Dateien zu manipulieren
- Sicherheitsvorkehrungen zu umgehen
Am I affected?
Affected according to the BSI:
- Red Hat Enterprise Linux
- Fedora Linux
- IBM i
- IGEL OS
- Red Hat OpenShift Container Platform
- Microsoft Azure Linux azl3
- Dell PowerScale OneFS
- Arista EOS
- NetApp ActiveIQ Unified Manager
- RESF Rocky Linux
- SUSE Linux
- SUSE openSUSE
and 9 more
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source OpenSSH 10.4
- SEPPmail Secure E-Mail Gateway 15.0.6
- Dell Secure Connect Gateway 5.36.00.16
- Dell integrated Dell Remote Access Controller 7.00.00.185
- Dell integrated Dell Remote Access Controller 7.30.30.54
- Dell integrated Dell Remote Access Controller 1.30.40.51
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.
