I Bitbucket Server, ett paket f\u00f6r distribution av webgr\u00e4nssnitt f\u00f6r att arbeta med git-repositorier, har en kritisk s\u00e5rbarhet (CVE-2022-43781) identifierats som m\u00f6jligg\u00f6r att en avl\u00e4gsen angripare kan f\u00e5 k\u00f6rning av kode p\u00e5 servern. S\u00e5rbarheten kan utnyttjas av en icke-autentiserad anv\u00e4ndare om sj\u00e4lvregistrering \u00e4r aktiverad p\u00e5 servern (inst\u00e4llningen \"Till\u00e5t offentlig registrering\" \u00e4r aktiverad). Utnyttjande \u00e4r ocks\u00e5 m\u00f6jligt f\u00f6r en autentiserad anv\u00e4ndare som har r\u00e4tt att \u00e4ndra anv\u00e4ndarnamn (dvs. har befogenheter som ADMIN eller SYS_ADMIN). Detaljer ges f\u00f6r n\u00e4rvarande inte, endast att problemet beror p\u00e5 m\u00f6jligheten att injicera kommandon via milj\u00f6variabler. <\/p>\n

Problemet f\u00f6rekommer i versionerna 7.x och 8.x, och har \u00e5tg\u00e4rdats i utg\u00e5vorna av Bitbucket Server och 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. S\u00e5rbarheten manifesterar sig inte i den molnbaserade tj\u00e4nsten bitbucket.org, utan p\u00e5verkar endast produkter f\u00f6r installation p\u00e5 egna resurser. Problemet manifesterar sig inte heller i servrar<\/a> Bitbucket Server och Data Center som anv\u00e4nder PostgreSQL som databas f\u00f6r datalagring.
