WID-SEC-2022-1492 · first 21.09.2022 · updated 07.01.2026 · CVSS 8,6
What it is about
BIND (Berkeley Internet Name Domain) ist ein Open-Source-Softwarepaket, das einen Domain-Name-System-Server implementiert. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Internet Systems Consortium BIND ausnutzen, um einen Denial of Service Angriff durchzuführen.
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
- einen Denial of Service Angriff durchzuführen
Am I affected?
Affected according to the BSI:
- IBM VIOS 3.1
- IBM AIX 7.1
- Broadcom Brocade SANnav <2.4.0
- Broadcom Brocade SANnav <2.3.1b
- Open Source CentOS
- Debian Linux
- Amazon Linux 2
- IBM AIX 7.2
- Red Hat Enterprise Linux
- Ubuntu Linux
- F5 BIG-IP
- SUSE Linux
and 18 more
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Broadcom Brocade SANnav 2.4.0
- Broadcom Brocade SANnav 2.3.1b
- Internet Systems Consortium BIND 9.16.33
- Internet Systems Consortium BIND 9.18.7
- Internet Systems Consortium BIND 9.19.1
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.
