Omschrijving

Atlassian heeft kwetsbaarheden verholpen in diverse producten zoals Bamboo, Bitbucket, Confluence, Jira, Crowd en Fisheye. De kwetsbaarheden bevinden zich in diverse Third-Party producten waar eerder updates voor zijn verschenen. Atlassian heeft deze updates verwerkt in de eigen producten.

Kwaadwillenden kunnen de kwetsbaarheden misbruiken om een Denial-of-Service te veroorzaken, willekeurige code uit te voeren middels het injecteren van scripts of malafide SQL-quieries en/of gegevens te manipuleren of toegang te krijgen tot gevoelige gegevens.

Enkele kwetsbaarheden hebben van origine een hoge CVSS score van 9 of meer en zijn door de ontwikkelaars van het kwetsbare product aanvankelijk ingeschaald als 'kritiek'. Door de wijze waarop Atlassian gebruik maakt van deze Third-party modules, is direct misbruik van deze kwetsbaarheden onwaarschijnlijker, waardoor Atlassian de risico's van misbruik voor hun producten lager inschaalt. Echter, door de grote hoeveelheid verholpen kwetsbaarheden adviseert het NCSC wel om deze updates met voorrang in te zetten, met name op systemen die toegankelijk zijn vanaf publieke infrastructuur.

Oplossingen

Atlassian heeft updates uitgebracht voor Bamboo, Bitbucket, Confluence, Jira, Crowd en Fisheye. Zie de bijgevoegde referenties voor meer informatie.
