{"id":"CVE-2025-47812","url":"https://www.cyber-defence.io/tools/cve/CVE-2025-47812","generatedAt":"2026-10-31T06:58:08.600Z","title":"Wing FTP Server Improper Neutralization of Null Byte or NUL Character Vulnerability","description":"In Wing FTP Server before 7.4.4. the user and admin web interfaces mishandle '\\0' bytes, ultimately allowing injection of arbitrary Lua code into user session files. This can be used to execute arbitrary system commands with the privileges of the FTP service (root or SYSTEM by default). This is thus a remote code execution vulnerability that guarantees a total server compromise. This is also exploitable via anonymous FTP accounts.","published":"2025-07-10T17:15:47.000Z","lastModified":"2026-06-17T09:28:43.000Z","status":"Analyzed","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":10,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"},"cwe":["CWE-158"],"affected":["wftpserver/wing ftp server"],"epss":{"score":0.93884,"percentile":0.99844,"date":"2026-10-30","history":[]},"kev":{"listed":true,"dateAdded":"2025-07-14","dueDate":"2025-08-04","knownRansomwareCampaignUse":"Unknown","notes":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.\nhttps://www.wftpserver.com/serverhistory.htm ; https://nvd.nist.gov/vuln/detail/CVE-2025-47812"},"exploits":{"count":1,"verified":false,"firstPublished":"2025-07-02","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":52347,"kind":"exploit","title":"Wing FTP Server 7.4.3 - Unauthenticated Remote Code Execution  (RCE)","url":"https://www.exploit-db.com/exploits/52347","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/multiple/remote/52347.py","file":"exploits/multiple/remote/52347.py","published":"2025-07-02","added":"2025-07-02","updated":"2025-07-02","author":"4m3rr0r","type":"remote","platform":"multiple","port":null,"verified":false,"codes":["CVE-2025-47812"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"Known to be exploited in the wild (CISA KEV, CISA remediation deadline 4 August 2025).
