CVE-2019-13270 : What You Need to Know
Learn about CVE-2019-13270 affecting Edimax BR-6208AC V1 devices, allowing data leakage between primary and secondary networks. Find mitigation steps and prevention measures.
Edimax BR-6208AC V1 devices have a vulnerability that allows data leakage between a primary and secondary network due to insufficient segregation. When data is transferred from the primary to the secondary network, an IGMP Membership Query packet is generated and sent to both networks.
Understanding CVE-2019-13270
This CVE involves a lack of proper network segregation in Edimax BR-6208AC V1 devices, leading to potential data leakage between the primary and secondary networks.
What is CVE-2019-13270?
The vulnerability in Edimax BR-6208AC V1 devices allows an attacker to transfer data between the primary and secondary networks by manipulating IGMP group membership.
The Impact of CVE-2019-13270
This vulnerability could result in unauthorized access to sensitive data, compromising the security and privacy of both networks.
Technical Details of CVE-2019-13270
Edimax BR-6208AC V1 devices are affected by a flaw that enables data transfer between the primary and secondary networks.
Vulnerability Description
