Attackers can submit a crafted request body containing an internal or loopback URL, which is treated as a DIRECT request skipping private-address filtering, causing the server to fetch and proxy back arbitrary private-network and cloud metadata content.","cvssScore":4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N","cwes":["CWE-918"],"vendors":[],"products":[],"references":[{"url":"https://github.com/ONLYOFFICE/DocumentServer/blob/master/CHANGELOG.md#1000","tags":[]},{"url":"https://github.com/ONLYOFFICE/DocumentServer/releases/tag/v10.0.0","tags":[]},{"url":"https://www.vulncheck.com/advisories/onlyoffice-documentserver-before-ssrf-via-downloadfile-isinjwttoken-bypass","tags":[]}],"exploitRefs":[{"url":"https://github.com/ONLYOFFICE/DocumentServer/blob/master/CHANGELOG.md#1000","tags":[]},{"url":"https://github.com/ONLYOFFICE/DocumentServer/releases/tag/v10.0.0","tags":[]}],"hasPoc":true,"ai":null}
