CVE-2023-31994 : Exploit Details and Defense Strategies
Learn about CVE-2023-31994 impacting Hanwha IP Cameras, allowing DoS attacks via empty UDP packets. Find mitigation steps and preventive measures for enhanced security.
Certain Hanwha products are vulnerable to Denial of Service (DoS) attacks due to a specific vector. When an empty UDP packet is sent to the listening service, it causes the service thread to render the service non-functional, resulting in a DoS attack. This vulnerability impacts IP Camera models ANE-L7012R 1.41.01 and XNV-9082R 2.10.02.
