Description
Description
HCL DFXAnalytics is affected by a Buffer Overflow vulnerability that can lead to a Denial of Service (DoS). The application fails to properly validate input sizes, allowing an attacker to pass an excessive amount of information into a memory container, which can cause the system to crash or become unresponsive. To mitigate this flaw, comprehensive input length checks must be implemented and enforced on both the client and server sides.
