Dans Bitbucket Server, le package pour le d\u00e9ploiement d'une interface web pour travailler avec des d\u00e9p\u00f4ts git, une vuln\u00e9rabilit\u00e9 critique (CVE-2022-43781) a \u00e9t\u00e9 identifi\u00e9e, permettant \u00e0 un attaquant distant d'ex\u00e9cuter du code sur le serveur. Cette vuln\u00e9rabilit\u00e9 peut \u00eatre exploit\u00e9e par un utilisateur non authentifi\u00e9 si l'inscription autonome est autoris\u00e9e sur le serveur (param\u00e8tre \u00ab Allow public signup \u00bb activ\u00e9). L'exploitation est \u00e9galement possible par un utilisateur authentifi\u00e9 qui dispose des droits pour modifier le nom d'utilisateur (c'est-\u00e0-dire qui a des privil\u00e8ges ADMIN ou SYS_ADMIN). Les d\u00e9tails ne sont pas encore fournis, il est seulement connu que le probl\u00e8me est caus\u00e9 par la possibilit\u00e9 de substitution de commandes via des variables d'environnement. <\/p>\n

Le probl\u00e8me appara\u00eet dans les versions 7.x et 8.x, et a \u00e9t\u00e9 corrig\u00e9 dans les versions Bitbucket Server et Bitbucket Data Center 8.5.0, 8.4.2, 7.17.12, 7.21.6, 8.0.5, 8.1.5, 8.3.3, 8.2.4, 7.6.19. La vuln\u00e9rabilit\u00e9 ne se manifeste pas dans le service cloud bitbucket.org, mais concerne uniquement les produits install\u00e9s sur site. Ce probl\u00e8me ne se pr\u00e9sente \u00e9galement pas sur serveurs<\/a> Bitbucket Server et Data Center, qui utilisent une base de donn\u00e9es PostgreSQL pour le stockage des donn\u00e9es.
