Feiten
Cisco heeft kwetsbaarheden verholpen in verschillende Cisco Unified Communications producten.
Interpretaties
De kwetsbaarheden omvatten een kritieke kwetsbaarheid die ongeauthenticeerde externe aanvallers in staat stelt om willekeurige commando's op het besturingssysteem van het apparaat uit te voeren. Dit is te wijten aan onjuiste validatie van gebruikersinvoer in HTTP-verzoeken, wat aanvallers in staat kan stellen om gebruikersniveau toegang te krijgen en mogelijk hun privileges naar root te verhogen. Daarnaast zijn er meerdere kwetsbaarheden in de webgebaseerde beheersinterfaces van Cisco Packaged Contact Center Enterprise en Cisco Unified Contact Center Enterprise, die kunnen worden misbruikt door geauthenticeerde externe aanvallers voor cross-site scripting (XSS) aanvallen. Ook bevat de Cisco Intersight Virtual Appliance een kwetsbaarheid in de read-only onderhoudshell die geauthenticeerde lokale aanvallers met administratieve privileges in staat stelt om hun privileges naar root te verhogen. Tot slot is er een kwetsbaarheid in de SSH-service van Cisco IEC6400 Wireless Backhaul Edge Compute Software die ongeauthenticeerde externe aanvallers in staat stelt om een denial of service (DoS) aanval te initiëren, waardoor de SSH-service onresponsief wordt.
Oplossingen
Cisco heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
