Joomla: Mehrere Schwachstellen
WID-SEC-2024-1891 · first 21.08.2024 · updated 09.07.2026 · CVSS 6,5
What it is about
Joomla ist ein freies Content-Management-System, basierend auf der Scriptsprache PHP und einer SQL-Datenbank. Über zahlreiche Extensions kann der Funktionsumfang der Core-Installation individuell erweitert werden. Ein entfernter, anonymer oder authentisierter Angreifer kann mehrere Schwachstellen in Joomla ausnutzen, um falsche Informationen darzustellen, einen Cross-Site-Scripting-Angriff zu starten und Daten zu verändern.
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
- falsche Informationen darzustellen
- einen Cross-Site-Scripting-Angriff zu starten
- Daten zu verändern
Am I affected?
Affected according to the BSI:
- Open Source Joomla <3.10.17-elts
- Open Source Joomla <4.4.7
- Open Source Joomla <5.1.3
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source Joomla 3.10.17-elts
- Open Source Joomla 4.4.7
- Open Source Joomla 5.1.3
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.
