WID-SEC-W-2022-0144
Vulnerability from csaf_certbund - Published: 2021-09-07 22:00 - Updated: 2024-12-01 23:00Es existiert eine Schwachstelle in Python. Der Fehler besteht, weil der von der AbstractBasicAuthHandler-Klasse des urllib-Moduls verwendete reguläre Ausdruck ineffizient ist. Ein entfernter anonymer Angreifer mit einem bösartigen HTTP-Server kann diese Schwachstelle ausnutzen, um einen Denial-of-Service-Zustand auszulösen. Zur erfolgreichen Ausnutzung ist eine Benutzeraktion erforderlich.
