However, it does not properly validate the uploaded file's contents and thus accepts any type of file, such as with a tickets.php request that is modified with a .html extension changed to a .exe extension. An attacker can leverage this vulnerability to upload arbitrary files on the web application having malicious content.","published":"2017-10-23T08:29:01.000Z","lastModified":"2026-06-17T01:07:55.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-434"],"affected":["osticket/osticket"],"epss":{"score":0.15564,"percentile":0.96817,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.12248,"percentile":0.96049},{"date":"2026-09-22","score":0.15564,"percentile":0.96679}]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2018-08-08","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":45169,"kind":"exploit","title":"osTicket 1.10.1 - Arbitrary File Upload","url":"https://www.exploit-db.com/exploits/45169","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/windows/webapps/45169.txt","file":"exploits/windows/webapps/45169.txt","published":"2018-08-08","added":"2018-08-08","updated":"2018-08-08","author":"Rajwinder Singh","type":"webapps","platform":"windows","port":null,"verified":false,"codes":["CVE-2017-15580"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 15.6%, higher than 97% of all known CVEs.
