Title: == GTA UTM Firewall GB 6.0.3 - Multiple Web Vulnerabilities Date: = 2012-09-30 References: === http://www.vulnerability-lab.com/get_content.php?id=579 VL-ID: = 579 Common Vulnerability Scoring System: 4 Introduction: = The GTA family of Internet security firewall UTM systems has been expanded to include three new gigabit appliances. The GB-2500 Firewall UTM Appliance is one of GTA s most capable firewalls, designed for businesses with extensive network demands. Featuring a powerful Intel Dual-Core processor, two gigabits of RAM and four gigabits of static memory, the GB-2500 easily handles intensive, resource-demanding network configurations. The GB-2100 Firewall UTM Appliance provides robust protection and network reliability for SME organizations. Featuring flexible configuration options, straightforward implementation and uncomplicated maintenance and monitoring, the GB-2100 presents comprehensive protection that is adaptable to any network environment. The GB-820 Firewall UTM Appliance is designed for smaller offices, providing gigabit performance with all the features and tools available in larger appliances, but in a space-saving desktop unit. Built-in VPN acceleration provides the GB-820 with increased throughput, allowing organizations to easily handle periods of increased VPN activity. All GTA Firewall UTM Appliances include our advanced firewall features - policy based NAT, virtual hosting via IP Aliasing, advanced routing such as BGP and Single-Sign on authentication - at no extra charge. Threat management features include DoS and an Intrusion Prevention System (IPS), basic content filtering and advanced email gateway features.

The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent). The first vulnerability is located in the user remote password and pre-shared secret input fields user account output listing. The secound vulnerability is located in the VPN Certificate emailAddress subject with affect on the VPN Details Listing section. Successful exploitation of the vulnerability can lead to session hijacking (manager/admin), persistent phishing stable (persistent) context manipulation in vulnerable modules or bound application sections. Exploitation requires low user inter action a privileged application account.
