Apache HTTP Server: Mehrere Schwachstellen
WID-SEC-2026-1824 · first 09.06.2026 · updated 23.10.2026 · CVSS 9,8
What it is about
Apache ist ein Webserver für verschiedene Plattformen. Ein Angreifer kann mehrere Schwachstellen in Apache HTTP Server ausnutzen, um beliebigen Programmcode auszuführen, Sicherheitsmaßnahmen zu umgehen, Cross-Site-Scripting-Angriffe durchzuführen, Daten zu verändern und offenzulegen, einen Denial-of-Service-Zustand zu verursachen oder andere nicht näher definierte Angriffe 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
- beliebigen Programmcode auszuführen
- Sicherheitsmaßnahmen zu umgehen
- Cross-Site-Scripting-Angriffe durchzuführen
- Daten zu verändern
- offenzulegen
- einen Denial-of-Service-Zustand zu verursachen oder andere nicht näher definierte Angriffe durchzuführen
Am I affected?
Affected according to the BSI:
- F5 F5OS
- Debian Linux
- Amazon Linux 2
- IBM Power Hardware Management Console
- Red Hat Enterprise Linux
- Ubuntu Linux
- SUSE Linux
- Oracle Linux
- IBM Tivoli Monitoring
- Red Hat JBoss Core Services
- IBM Business Automation Workflow
- IBM Rational ClearCase 9.1
and 16 more
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- IBM HTTP Server 8.5.5.30
- IBM HTTP Server 9.0.5.29
- Apache HTTP Server 2.4.68
- Fortinet FortiProxy 7.6.7
- Fortinet FortiProxy 7.4.15
- Dell Secure Connect Gateway 5.36.00.16
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.
