In the 2.x line from 2.8.0.0 until 2.19.6.0, and the 3.x line prior to 3.7.0.0, a remote authenticated user with basic read/search permissions can provide a crafted `cursor` parameter to the `plugins/sql` endpoint and trigger unsafe deserialization of untrusted data, resulting in arbitrary code execution on the server. This issue is fixed in repository releases 2.19.6.0 and 3.7.0.0.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-502"],"vendors":[],"products":[],"references":[{"url":"https://github.com/opensearch-project/sql/commit/402a284f1dff3545236480b67f860aa93fb667de","tags":[]},{"url":"https://github.com/opensearch-project/sql/commit/9ab50384d3ad571a14211415fba2f6d26d4c80db","tags":[]},{"url":"https://github.com/opensearch-project/sql/pull/5469","tags":[]},{"url":"https://github.com/opensearch-project/sql/pull/5572","tags":[]},{"url":"https://github.com/opensearch-project/sql/releases/tag/2.19.6.0","tags":[]},{"url":"https://github.com/opensearch-project/sql/releases/tag/3.7.0.0","tags":[]},{"url":"https://github.com/opensearch-project/sql/security/advisories/GHSA-r8cv-xvqm-4qj4","tags":[]}],"exploitRefs":[{"url":"https://github.com/opensearch-project/sql/commit/402a284f1dff3545236480b67f860aa93fb667de","tags":[]},{"url":"https://github.com/opensearch-project/sql/commit/9ab50384d3ad571a14211415fba2f6d26d4c80db","tags":[]},{"url":"https://github.com/opensearch-project/sql/pull/5469","tags":[]},{"url":"https://github.com/opensearch-project/sql/pull/5572","tags":[]},{"url":"https://github.com/opensearch-project/sql/releases/tag/2.19.6.0","tags":[]},{"url":"https://github.com/opensearch-project/sql/releases/tag/3.7.0.0","tags":[]},{"url":"https://github.com/opensearch-project/sql/security/advisories/GHSA-r8cv-xvqm-4qj4","tags":[]}],"hasPoc":true,"ai":null}
