An unauthenticated attacker could abuse improperly secured access to arbitrary files on the server (via /Electron/download directory traversal in conjunction with a path component that uses backslash characters), leading to cleartext credential disclosure. Afterwards, the authenticated attacker is able to upload a file that overwrites a 3CX service binary, leading to Remote Code Execution as NT AUTHORITY\\SYSTEM on Windows installations. NOTE: this issue exists because of an incomplete fix for CVE-2022-48482.","published":"2022-05-06T15:15:09.000Z","lastModified":"2026-06-17T04:37:51.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-522"],"affected":["3cx/3cx"],"epss":{"score":0.08346,"percentile":0.94918,"date":"2026-10-26","history":[{"date":"2026-10-06","score":0.08346,"percentile":0.94811}]},"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 (8.35%).
