Title: ====== GateProtect CC v3.0.1 - Memory Corruption Vulnerability Date: ===== 2011-10-27 References: =========== http://www.vulnerability-lab.com/get_content.php?id=53 VL-ID: ===== 53 Introduction: ============= Das Command Center® ermöglicht die zentrale Verwaltung, Konfiguration und Überwachung von bis zu 500 gateProtect xUTM Appliances bzw. Firewall-Systemen. Alle gateProtect Appliances, von der GPO 75 bis zur GPZ 2500, können zentral über das Command Center® verwaltet und konfiguriert werden. Dies ist besonders für Unternehmen wichtig, die mehrere Firewall-Systeme im Einsatz haben oder größere Rollouts planen.

Local attackers can implement large requests to block the configuration load. The bug results in a stable crash & the software needs to be repaired/restored after. Vulnerable Module(s): [+] New User & Firewall Admin Configuration Input Fields Picture(s): ../mem1.png ../mem2.png ../mem3.png ../mem4.png ../mem5.png Proof of Concept: ================= The vulnerability can be exploited by local low privileged attackers.
