Perl: Mehrere Schwachstellen
WID-SEC-2026-2309 · first 14.07.2026 · updated 14.10.2026 · CVSS 7,5
What it is about
Perl ist eine freie, plattformunabhängige und interpretierte Programmiersprache (Skriptsprache). Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Perl ausnutzen, um einen Denial of Service Angriff durchzuführen oder vertrauliche Informationen offenzulegen.
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 oder vertrauliche Informationen offenzulegen
Am I affected?
Affected according to the BSI:
- IBM AIX 7.3
- IBM VIOS 4.1
- Debian Linux
- Amazon Linux 2
- IBM AIX 7.2
- Red Hat Enterprise Linux
- IBM QRadar SIEM
- Red Hat OpenShift Container Platform
- RESF Rocky Linux
- SUSE Linux
- SUSE openSUSE
- Ubuntu Linux
and 4 more
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source Perl 5.43.10
- Open Source Perl 5.43.11
- 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.
