This may result in remote command execution. An attacker can use the instructor account to fully compromise the system using a crafted backup ZIP archive. This will allow for PHP files to be written to the web root, and for code to execute on the remote server.","published":"2019-05-17T22:29:00.000Z","lastModified":"2026-06-17T02:14:11.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":8.8,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-434"],"affected":["atutor/atutor"],"epss":{"score":0.08592,"percentile":0.95052,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.06778,"percentile":0.93768},{"date":"2026-09-22","score":0.08592,"percentile":0.94835}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (8.59%).
