A remote code execution (RCE) vulnerability in non-default configurations of Fluentd allows unauthenticated attackers to execute arbitrary code via specially crafted JSON payloads. Fluentd setups are only affected if the environment variable `FLUENT_OJ_OPTION_MODE` is explicitly set to `object`. Please note: The option FLUENT_OJ_OPTION_MODE was introduced in Fluentd version 1.13.2. Earlier versions of Fluentd are not affected by this vulnerability. This issue was patched in version 1.15.3. As a workaround do not use `FLUENT_OJ_OPTION_MODE=object`." } ] }, "impact": { "cvss": { "attackComplexity": "HIGH", "attackVector": "NETWORK", "availabilityImpact": "NONE", "baseScore": 3.1, "baseSeverity": "LOW", "confidentialityImpact": "LOW", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N", "version": "3.1" } }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-502: Deserialization of Untrusted Data" } ] } ] }, "references": { "reference_data": [ { "name": "https://github.com/fluent/fluentd/security/advisories/GHSA-fppq-mj76-fpj2", "refsource": "CONFIRM", "url": "https://github.com/fluent/fluentd/security/advisories/GHSA-fppq-mj76-fpj2" }, { "name": "https://github.com/fluent/fluentd/commit/48e5b85dab1b6d4c273090d538fc11b3f2fd8135", "refsource": "MISC", "url": "https://github.com/fluent/fluentd/commit/48e5b85dab1b6d4c273090d538fc11b3f2fd8135" }, { "refsource": "FEDORA", "name": "FEDORA-2023-6b9e2a6534", "url": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/MYD5QV66OLDHES6IKVYYM3Y3YID3VVCO/" } ] }, "source": { "advisory": "GHSA-fppq-mj76-fpj2", "discovery": "UNKNOWN" } }
