Attackers can exploit the standard cycler.__init__.__globals__.os gadget chain to execute arbitrary operating system commands as the DataGerry web process user, confirmed as root in default Docker deployments, achieving remote code execution.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-79","CWE-1336"],"vendors":[],"products":[],"references":[{"url":"https://docs.datagerry.com/en/latest/reference/changelog.html","tags":[]},{"url":"https://github.com/DataGerry/DataGerry/releases/tag/3.3.0","tags":[]},{"url":"https://www.vulncheck.com/advisories/datagerry-ssti-via-docapi-template-rendering","tags":[]}],"exploitRefs":[{"url":"https://github.com/DataGerry/DataGerry/releases/tag/3.3.0","tags":[]}],"hasPoc":true,"ai":null}
