{"id":"CVE-2023-38880","details":"The Community Edition version 9.0 of OS4ED's openSIS Classic has a broken access control vulnerability in the database backup functionality. Whenever an admin generates a database backup, the backup is stored in the web root while the file name has a format of \"opensisBackup\u003cdate\u003e.sql\" (e.g. \"opensisBackup07-20-2023.sql\"), i.e. can easily be guessed. This file can be accessed by any unauthenticated actor and contains a dump of the whole database including password hashes.","modified":"2026-08-27T03:57:00.514308015Z","published":"2023-11-20T00:00:00Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/38xxx/CVE-2023-38880.json","cna_assigner":"mitre"},"references":[{"type":"WEB","url":"https://github.com/dub-flow/vulnerability-research/tree/main/CVE-2023-38880"},{"type":"WEB","url":"https://www.os4ed.com/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/38xxx/CVE-2023-38880.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-38880"},{"type":"PACKAGE","url":"https://github.com/OS4ED/openSIS-Classic"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/OS4ED/openSIS-Classic","events":[{"introduced":"0d3e2d52912540d4edf87d5b8c005cd6b32ff313"},{"last_affected":"0d3e2d52912540d4edf87d5b8c005cd6b32ff313"}],"database_specific":{"extracted_events":[{"introduced":"9.0"},{"last_affected":"9.0"}],"source":"CPE_STRING","cpe":"cpe:2.3:a:os4ed:opensis:9.0:*:*:*:community:*:*:*"}}],"versions":["9.0","V9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-38880.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/os4ed/opensis-classic","events":[{"introduced":"0d3e2d52912540d4edf87d5b8c005cd6b32ff313"},{"last_affected":"0d3e2d52912540d4edf87d5b8c005cd6b32ff313"}],"database_specific":{"source":"CPE_STRING","cpe":"cpe:2.3:a:os4ed:opensis:9.0:*:*:*:community:*:*:*","extracted_events":[{"introduced":"9.0"},{"last_affected":"9.0"}]}}],"versions":["9.0","V9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-38880.json"}}],"schema_version":"1.9.0"}
