WID-SEC-2023-3007 · first 27.11.2023 · updated 17.09.2026 · CVSS 8,8
What it is about
Perl ist eine freie, plattformunabhängige und interpretierte Programmiersprache (Skriptsprache). Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Perl ausnutzen, um beliebigen Programmcode auszuführen.
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
- beliebigen Programmcode auszuführen
Am I affected?

- IBM AIX 7.3
- IBM VIOS 4.1
- Red Hat Enterprise Linux
- Fedora Linux
- Ubuntu Linux
- Oracle Linux
- Gentoo Linux
- OpenBSD OpenBSD 7.3
- OpenBSD OpenBSD 7.4
- Open Source Perl <5.34.2
- Open Source Perl <5.36.2
- Open Source Perl <5.38.1
and 3 more
The installed version is usually shown under “Help → About” or in the device’s admin interface.

Update to at least:
- Open Source Perl 5.34.2
- Open Source Perl 5.36.2
- Open Source Perl 5.38.1
