(0Day) (Pwn2Own) Softing edgeAggregator Client Cross-Site Scripting Remote Code Execution Vulnerability
Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Softing edgeAggregator. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of the input parameters provided to the edgeAggregetor client.
