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."}],"source":{"advisory":"GHSA-4mq7-w9r6-9975","discovery":"UNKNOWN"}},"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2023-49275","role":"CISA Coordinator","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-04-23T00:30:47.195400Z"}}}],"affected":[{"cpes":["cpe:2.3:a:wazuh:wazuh:-:*:*:*:*:*:*:*"],"vendor":"wazuh","product":"wazuh","versions":[{"status":"affected","version":"-"}],"defaultStatus":"unknown"}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-06-04T17:27:54.825Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T21:53:45.339Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/wazuh/wazuh/security/advisories/GHSA-4mq7-w9r6-9975","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/wazuh/wazuh/security/advisories/GHSA-4mq7-w9r6-9975"},{"name":"https://github.com/wazuh/wazuh/blob/e1d5231b31b68a75f3b8b33f833155b362411078/src/analysisd/decoders/syscollector.c#L1573","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/wazuh/wazuh/blob/e1d5231b31b68a75f3b8b33f833155b362411078/src/analysisd/decoders/syscollector.c#L1573"},{"name":"https://github.com/wazuh/wazuh/blob/e1d5231b31b68a75f3b8b33f833155b362411078/src/analysisd/decoders/syscollector.c#L1578","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/wazuh/wazuh/blob/e1d5231b31b68a75f3b8b33f833155b362411078/src/analysisd/decoders/syscollector.c#L1578"}]}]}}
