Summary
Wazuh vulnerable to NULL Pointer Dereference in wazuh-analysisd
Details

Wazuh is a free and open source platform used for threat prevention, detection, and response. A NULL pointer dereference was detected during fuzzing of the analysis engine, allowing malicious clients to DoS the analysis engine. The bug occurs when analysisd receives a syscollector message with the hotfix msg_type but lacking a timestamp. It uses cJSON_GetObjectItem() to get the timestamp object item and dereferences it without checking for a NULL value. A malicious client can DoS the analysis engine. This vulnerability is fixed in 4.7.1.
