What it is about

Python ist eine universelle, üblicherweise interpretierte, höhere Programmiersprache. Ein lokaler Angreifer kann eine Schwachstelle in Python ausnutzen, um einen Path-Traversal Angriff durchzuführen.

Under what conditions?

Only with access to the device or an account on it. Often the second step after a phishing email.

What can happen in the worst case

An attacker could use the vulnerability to

  • einen Path-Traversal Angriff durchzuführen

Am I affected?

Affected according to the BSI:

  • Dell NetWorker
  • Amazon Linux 2
  • Red Hat Enterprise Linux
  • Fedora Linux
  • SUSE Linux
  • IBM SPSS Modeler
  • SUSE openSUSE
  • Dell Avamar
  • Open Source Python CPython <3.15.0
  • Dell Secure Connect Gateway <5.36.00.16

The installed version is usually shown under “Help → About” or in the device’s admin interface.

What helps?

Update to at least:

  • Open Source Python CPython 3.15.0
  • 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.
