Summary
GitLab Inc. heeft meerdere kwetsbaarheden verholpen in GitLab Community Edition en Enterprise Edition, specifiek in versies variërend van 9.2 tot voor 18.11.1, inclusief diverse 18.x releases.
Details
Interpretaties
De kwetsbaarheden betreffen verschillende componenten van GitLab, waaronder de discussions endpoint, GraphQL API, note retrieval, issue import, Mermaid sandbox, Storybook development environment, issue rendering, web interface en Virtual Registries. Geauthenticeerde gebruikers kunnen door onvoldoende resource limits of onjuiste inputvalidatie resource-exhaustie veroorzaken, wat leidt tot Denial-of-Service. Daarnaast zijn er problemen met onjuiste autorisatiecontroles waardoor project owners group fork preventie kunnen omzeilen, en met onvoldoende CSRF-bescherming waardoor ongeauthenticeerde gebruikers GraphQL mutaties kunnen uitvoeren. Verder is er een cross-site scripting (XSS) kwetsbaarheid die ongeauthenticeerde gebruikers toestaat om JavaScript code in de browser van een gebruiker uit te voeren. Ook kunnen gebruikers door onjuiste toegangscontrole de titels van vertrouwelijke issues in publieke projecten inzien en toegang krijgen tot Virtual Registries via onjuist gescopeerde credentials. Sommige kwetsbaarheden maken het mogelijk om ongeautoriseerde content te injecteren in browser sessies van andere gebruikers. De kwetsbaarheden zijn aanwezig in meerdere opeenvolgende versies en betreffen zowel Community als Enterprise edities van GitLab.
Oplossingen
GitLab Inc. heeft updates en patches uitgebracht in versies vanaf 18.9.6, 18.10.4 en 18.11.1 om deze kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
