{"id":"CVE-2023-49275","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.","aliases":["GHSA-4mq7-w9r6-9975"],"modified":"2026-04-10T05:05:01.589233Z","published":"2024-04-19T14:24:25.343Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-476"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/49xxx/CVE-2023-49275.json"},"references":[{"type":"WEB","url":"https://github.com/wazuh/wazuh/blob/e1d5231b31b68a75f3b8b33f833155b362411078/src/analysisd/decoders/syscollector.c#L1573"},{"type":"WEB","url":"https://github.com/wazuh/wazuh/blob/e1d5231b31b68a75f3b8b33f833155b362411078/src/analysisd/decoders/syscollector.c#L1578"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/49xxx/CVE-2023-49275.json"},{"type":"ADVISORY","url":"https://github.com/wazuh/wazuh/security/advisories/GHSA-4mq7-w9r6-9975"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-49275"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wazuh/wazuh","events":[{"introduced":"1dfef3696c85a19283be96b2c60218888a130a1c"},{"fixed":"5a0abd9df1faa5f4b93848cebed90c39f76d6c64"}]}],"versions":["v3.12.0","v3.13.0","v3.13.1","v3.2.0","v3.5.0","v3.6.0","v3.6.1","v3.7.0","v3.8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-49275.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
