What it is about
ILIAS ist eine Open Source e-Learning Lösung. Ein Angreifer kann mehrere Schwachstellen in ILIAS ausnutzen, um Dateien zu manipulieren, um Sicherheitsvorkehrungen zu umgehen, und um einen nicht näher spezifizierten Angriff durchzuführen.
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
- Dateien zu manipulieren
- Sicherheitsvorkehrungen zu umgehen
- einen nicht näher spezifizierten Angriff durchzuführen
Am I affected?
Affected according to the BSI:
- Open Source ILIAS <9.20
- Open Source ILIAS <10.8
- Open Source ILIAS <11.1
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source ILIAS 9.20
- Open Source ILIAS 10.8
- Open Source ILIAS 11.1
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.
