Title

Cisco Packaged Contact Center Enterprise & Cisco Unified Contact Center Enterprise Cross-Site Scripting Vulnerability

Summary

Multiple vulnerabilities in the web-based management interface of Cisco Packaged Contact Center Enterprise (Packaged CCE) and Cisco Unified Contact Center Enterprise (Unified CCE) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device.  These vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. An attacker could exploit these vulnerabilities by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit these vulnerabilities, the attacker must have valid administrative credentials.

Severity ?

4.8 (Medium)

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.
