- Missing Authentication for Critical Function
Omschrijving
cPanel heeft een kwetsbaarheid verholpen in cPanel en WHM producten, inclusief versies na 11.40 en vóór de specifieke gepatchte releases.
De kwetsbaarheid betreft een authenticatieomzeiling die ontstaat door CRLF-injectie in sessiebestanden, waardoor aanvallers sessies kunnen vervalsen. Daarnaast is de loginflow zelf kwetsbaar, waardoor niet-geauthenticeerde externe aanvallers de authenticatiemechanismen kunnen omzeilen. Hierdoor kan ongeautoriseerde toegang tot het WHM control panel met rootrechten worden verkregen.
Oplossingen
cPanel heeft updates uitgebracht om de kwetsbaarheid te verhelpen. Zie bijgevoegde referenties voor meer informatie.
