De tweede kwetsbaarheid betreft command injection en treft naast ESG ook de Load Balancer Application Delivery Controller (ADC), Message Archiver (BMA), WAF Control Center (WCC), Web Application Firewall (WAF) en Web Security Gateway (WSG).\n\nVolgens Barracuda is voor succesvolle exploitatie toegang tot de administratieve interface van een kwetsbaar product vereist. Wanneer beide kwetsbaarheden in combinatie worden misbruikt, kan een aanvaller autorisatiecontroles omzeilen en roottoegang tot het apparaat verkrijgen.\n\n", "title": "Interpretaties" }, { "category": "description", "text": "Barracuda heeft beveiligingspatches beschikbaar gesteld en adviseert klanten hun systemen bij te werken naar de nieuwste firmwareversie en alle beschikbare beveiligingsupdates te installeren.
