WID-SEC-2022-0575 · first 02.05.2022 · updated 21.09.2026 · CVSS 8,8
What it is about
Python ist eine universelle, üblicherweise interpretierte höhere Programmiersprache. Ein entfernter, anonymer Angreifer kann eine Schwachstelle in Python 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?
