{"id":"CVE-2025-34110","details":"A directory traversal vulnerability exists in ColoradoFTP Server ≤ 1.3 Build 8 for Windows, allowing unauthenticated attackers to read or write arbitrary files outside the configured FTP root directory. The flaw is due to insufficient sanitation of user-supplied file paths in the FTP GET and PUT command handlers. Exploitation is possible by submitting traversal sequences during FTP operations, enabling access to system-sensitive files. This issue affects only the Windows version of ColoradoFTP.","modified":"2026-04-12T15:36:24.285270Z","published":"2025-07-15T13:15:30.833Z","references":[{"type":"WEB","url":"https://raw.githubusercontent.com/rapid7/metasploit-framework/master/modules/auxiliary/scanner/ftp/colorado_ftp_traversal.rb"},{"type":"WEB","url":"https://www.exploit-db.com/exploits/40231"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/colorado-ftp-server-path-traversal-information-disclosure"},{"type":"FIX","url":"https://bitbucket.org/nolife/coloradoftp/commits/16a60c4a74ef477cd8c16ca82442eaab2fbe8c86"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://bitbucket.org/nolife/coloradoftp","events":[{"introduced":"0"},{"fixed":"16a60c4a74ef477cd8c16ca82442eaab2fbe8c86"}]}],"versions":["1.3"],"database_specific":{"vanir_signatures_modified":"2026-04-12T15:36:24Z","source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-34110.json","vanir_signatures":[{"digest":{"line_hashes":["251145532788171280305768876642995824501","7093707141429545515907161534099995653","312538698378582257593424737016874255716"],"threshold":0.9},"target":{"file":"coloradoftp/plugins/xmlfs/src/main/java/com/coldcore/coloradoftp/plugin/xmlfs/resolver/GenericVirtualPathResolver.java"},"id":"CVE-2025-34110-147b8826","deprecated":false,"source":"https://bitbucket.org/nolife/coloradoftp@16a60c4a74ef477cd8c16ca82442eaab2fbe8c86","signature_type":"Line","signature_version":"v1"},{"digest":{"length":597,"function_hash":"30800469746312930370171075578529644280"},"target":{"function":"fixVirtualParentRefs","file":"coloradoftp/plugins/xmlfs/src/main/java/com/coldcore/coloradoftp/plugin/xmlfs/resolver/GenericVirtualPathResolver.java"},"id":"CVE-2025-34110-9048897e","deprecated":false,"source":"https://bitbucket.org/nolife/coloradoftp@16a60c4a74ef477cd8c16ca82442eaab2fbe8c86","signature_type":"Function","signature_version":"v1"}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
