Feiten
Arcserve heeft kwetsbaarheden verholpen in Arcserve Unified Data Protection (UDP) voor alle versies vóór 10.2.
Interpretaties
De kwetsbaarheden omvatten een authenticatie-bypass die ongeauthenticeerde kwaadwillenden toegang geeft tot beschermde functies, een reflected cross-site scripting (XSS) kwetsbaarheid die het mogelijk maakt voor kwaadwillenden om willekeurige JavaScript-code uit te voeren in de browsers van gebruikers, en heap-based buffer overflow kwetsbaarheden die ernstige gevolgen kunnen hebben, zoals applicatiecrashes en remote code-executie.
Oplossingen
Arcserve heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
