Attackers can request internal resources such as cloud instance metadata services or localhost-bound management interfaces, save the fetched response as a file in their own user folder, and retrieve it via the download endpoint to exfiltrate sensitive internal data or enumerate internal network hosts and ports.","cvssScore":5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","cwes":["CWE-918"],"vendors":[],"products":[],"references":[{"url":"https://github.com/oqtane/oqtane.framework/releases/tag/v10.3.0","tags":[]},{"url":"https://www.oqtane.org/blog/!/160/oqtane-10-3-released","tags":[]},{"url":"https://www.vulncheck.com/advisories/oqtane-framework-before-ssrf-via-file-upload-from-url","tags":[]}],"exploitRefs":[{"url":"https://github.com/oqtane/oqtane.framework/releases/tag/v10.3.0","tags":[]}],"hasPoc":true,"ai":null}
