Feiten
GitLab heeft kwetsbaarheden verholpen in GitLab CE/EE.
Interpretaties
De kwetsbaarheden omvatten verschillende problemen, waaronder de mogelijkheid voor geauthenticeerde gebruikers om externe API-aanroepen te misbruiken, wat kan leiden tot een Denial-of-Service. Daarnaast konden geauthenticeerde gebruikers via GraphQL ongeautoriseerde wijzigingen aanbrengen in projectconfiguraties en AI-instellingen van ongeautoriseerde namespaces. Een andere kwetsbaarheid stelde ongeauthenticeerde gebruikers in staat om willekeurige code uit te voeren in de browser van een geauthenticeerde gebruiker via een kwaadaardige webpagina. Bovendien konden geauthenticeerde gebruikers gevoelige informatie lekken door speciaal vervaardigde afbeeldingen te gebruiken die de bescherming van de asset proxy omzeilden. Ten slotte was er een kwetsbaarheid die het mogelijk maakte om opgeslagen cross-site scripting (XSS) uit te voeren via GitLab Flavored Markdown, wat de beveiliging van de applicatie in gevaar kon brengen.
Oplossingen
GitLab heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
