What it is about
Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Red Hat Enterprise Linux ausnutzen, um beliebigen Programmcode auszuführen, Informationen offenzulegen, einen Denial of Service Zustand herbeizuführen, Dateien zu manipulieren oder Sicherheitsvorkehrungen zu umgehen.
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
- beliebigen Programmcode auszuführen
- Informationen offenzulegen
- einen Denial of Service Zustand herbeizuführen
- Dateien zu manipulieren oder Sicherheitsvorkehrungen zu umgehen
Am I affected?
Affected according to the BSI:
- Red Hat Enterprise Linux
- Oracle Linux
- Red Hat Enterprise Linux 8
- HCL BigFix
- JFrog Artifactory <7.46.3
- HCL AppScan Enterprise <10.9.0
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- JFrog Artifactory 7.46.3
- HCL AppScan Enterprise 10.9.0
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.
