Descriptions

Wazuh is a free and open source platform used for threat prevention, detection, and response. Prior to 4.11.0, DecodeCiscat() implementation does not check the return the value of cJSON_GetObjectItem() for a possible NULL value in case of an error. A compromised agent can cause a crash of analysisd by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can cause analysisd to crash and make it unavailable. This vulnerability is fixed in 4.11.0.
