In Bitbucket Server, einem Paket zur Bereitstellung einer Weboberfl\u00e4che f\u00fcr die Arbeit mit Git-Repositorys, wurde eine kritische Sicherheitsanf\u00e4lligkeit (CVE-2022-36804) entdeckt. Diese erm\u00f6glicht es einem entfernten Angreifer mit Leserechten auf private oder \u00f6ffentliche Repositories, durch das Senden einer speziell gestalteten HTTP-Anfrage willk\u00fcrlichen Code auf dem Server auszuf\u00fchren. Das Problem tritt ab der Version 6.10.17 auf und wurde in den Versionen Bitbucket Server und Bitbucket Data Center 7.6.17, 7.17.10, 7.21.4, 8.0.3, 8.2.2 und 8.3.1 behoben. Die Sicherheitsanf\u00e4lligkeit tritt nicht im Cloud-Dienst bitbucket.org auf, sondern betrifft ausschlie\u00dflich lokal installierte Produkte. <\/p>\n

Eine Sicherheitsanf\u00e4lligkeit wurde von einem Sicherheitsforscher im Rahmen der Bugcrowd Bug Bounty Initiative entdeckt, die Belohnungen f\u00fcr die Auffindung bisher unbekannter Schwachstellen vorsieht. Die ausgezahlte Belohnung betrug 6.000 Dollar. Details zur Angriffsmethode und ein Exploit-Prototyp sollen 30 Tage nach der Ver\u00f6ffentlichung des Patches offengelegt werden. Als Ma\u00dfnahme zur Risikominderung bei Angriffen auf die Systeme wird empfohlen, den \u00f6ffentlichen Zugriff auf die Repositories durch Setzen der Einstellung 'feature.public.access=false' einzuschr\u00e4nken.
