{"id":"CVE-2023-49275","state":"PUBLISHED","title":"Wazuh vulnerable to  NULL Pointer Dereference in wazuh-analysisd","description":"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.","publishedAt":"2024-04-19T14:24:25.343Z","updatedAt":"2024-08-02T21:53:45.339Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["wazuh wazuh"],"affected":[{"vendor":"wazuh","product":"wazuh","versions":[{"version":">= 3.2.0, < 4.7.1","status":"affected"}]}],"references":["https://github.com/wazuh/wazuh/security/advisories/GHSA-4mq7-w9r6-9975","https://github.com/wazuh/wazuh/blob/e1d5231b31b68a75f3b8b33f833155b362411078/src/analysisd/decoders/syscollector.c#L1573","https://github.com/wazuh/wazuh/blob/e1d5231b31b68a75f3b8b33f833155b362411078/src/analysisd/decoders/syscollector.c#L1578"],"weaknesses":["CWE-476"],"ingestedAt":"2026-10-29T20:06:24.729Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/49xxx/CVE-2023-49275.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-49275","state":"PUBLISHED","datePublished":"2024-04-19T14:24:25.343Z","dateUpdated":"2024-08-02T21:53:45.339Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-11-24T16:45:24.311Z"},"containers":{"cna":{"title":"Wazuh vulnerable to  NULL Pointer Dereference in wazuh-analysisd","descriptions":[{"lang":"en","value":"Wazuh is a free and open source platform used for threat prevention, detection, and response.
