Name of the Vulnerable Software and Affected Versions OpenHarmony versions prior to 3.1.2

Description The issue is caused by an incorrect configuration of the cJSON library, leading to a stack overflow vulnerability during recursive parsing. This allows LAN attackers to launch a Denial of Service (DoS) attack against all network devices.

Recommendations For OpenHarmony versions prior to 3.1.2, update to a version that correctly configures the cJSON library to prevent the stack overflow vulnerability. As a temporary workaround, consider restricting access to the network to minimize the risk of exploitation by LAN attackers.
