This can allow a user to request internal services for a full read SSRF, returning any data from the internal network.\n\nthe application is using a whitelist, but the whitelist can be bypassed with @ and encoded value of @ (%40) GET /proxy/?url=http://development.demo.geonode.org%40geoserver:8080/geoserver/web \nThis will trick the application that the first host is a whitelisted address, but the browser will use @ or %40 as a credential to the host geoserver on port 8080, this will return the data to that host on the response.\n\n![image](https://user-images.githubusercontent.com/35967437/264379628-8cecbc56-be6c-49dc-abe8-0baf8b8695cc.png)\n\n","aliases":["CVE-2023-42439","PYSEC-2023-176"],"modified":"2024-09-20T20:23:25.532285Z","published":"2023-09-20T23:04:44Z","database_specific":{"cwe_ids":["CWE-918"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2023-09-20T23:04:44Z","nvd_published_at":"2023-09-15T21:15:11Z"},"references":[{"type":"WEB","url":"https://github.com/GeoNode/geonode/security/advisories/GHSA-pxg5-h34r-7q8p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-42439"},{"type":"WEB","url":"https://github.com/GeoNode/geonode/commit/79ac6e70419c2e0261548bed91c159b54ff35b8d"},{"type":"PACKAGE","url":"https://github.com/GeoNode/geonode"},{"type":"WEB","url":"https://github.com/GeoNode/geonode/releases/tag/4.1.3"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/geonode/PYSEC-2023-176.yaml"}],"affected":[{"package":{"name":"geonode","ecosystem":"PyPI","purl":"pkg:pypi/geonode"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.2.0"},{"fixed":"4.1.3.post1"}]}],"versions":["3.2.0","3.2.1","3.2.2","3.2.3","3.2.3.post1","3.2.4","3.3.0","3.3.1","3.3.1.post1","3.3.2","3.3.2.post1","3.3.2.post2","3.3.3","4.0.0","4.0.0.post1","4.0.0rc0","4.0.0rc1","4.0.1","4.0.2","4.0.3","4.1.0","4.1.1","4.1.2","4.1.3"],"database_specific":{"last_known_affected_version_range":"\u003c= 4.1.2","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/09/GHSA-pxg5-h34r-7q8p/GHSA-pxg5-h34r-7q8p.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
