An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2015-3306 in the wild since at least 8 Oct 2026.\n\nAffected product: Debian Debian Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2015-3306/ (Markdown: https://insights.sbomify.com/CVE-2015-3306/index.md)","id":"CVE-2015-3306","markdown":"https://insights.sbomify.com/CVE-2015-3306/index.md","name":"CVE-2015-3306","record":{"aliases":["DEBIAN-CVE-2015-3306","DSA-3263-1","GHSA-4mfj-5wr8-x32q","UBUNTU-CVE-2015-3306"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"ProFTPD FTP server","requires_auth":"none","summary":"Remote attackers can read and write arbitrary files on ProFTPD servers using mod_copy commands, requiring the module to be enabled.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"tumbleweed","vendor":"opensuse"},{"product":"proftpd","vendor":"proftpd"},{"product":"linux_enterprise_server","vendor":"suse"}],"cvss":{"score":10,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"The mod_copy module in ProFTPD 1.3.5 allows remote attackers to read and write to arbitrary files via the site cpfr and site cpto commands.","ecosystems":[],"exploits":{"exploitdb":4,"first_seen":"2015-04-13","github_poc":18,"max_poc_stars":152,"metasploit":1,"nuclei":1,"refs":[{"date":"2017-01-08T14:19:51Z","kind":"github_poc","ref":"https://github.com/t0kx/exploit-CVE-2015-3306","stars":152,"title":"ProFTPd 1.3.5 - (mod_copy) Remote Command Execution exploit and vulnerable container"},{"date":"2015-04-26T14:14:34Z","kind":"github_poc","ref":"https://github.com/nootropics/propane","stars":2,"title":"Exploits the arbitrary file write bug in proftpd (CVE-2015-3306) attempts code execution"},{"date":"2015-04-21T12:51:51Z","kind":"github_poc","ref":"https://github.com/xyk0x/cpx_proftpd","stars":1,"title":"Tool for exploit CVE-2015-3306"},{"date":"2017-07-29T04:31:10Z","kind":"github_poc","ref":"https://github.com/davidtavarez/CVE-2015-3306","stars":1,"title":"ProFTPd 1.3.5 - File Copy"},{"date":"2020-10-16T19:58:13Z","kind":"github_poc","ref":"https://github.com/cd6629/CVE-2015-3306-Python-PoC","stars":1,"title":"Converted with tweaks from a metasploit module as an exercise for OSCP studying and exploit development"},{"date":"2021-05-16T18:57:14Z","kind":"github_poc","ref":"https://github.com/0xm4ud/ProFTPD_CVE-2015-3306","stars":1,"title":null},{"date":"2021-08-21T17:42:05Z","kind":"github_poc","ref":"https://github.com/jptr218/proftpd_bypass","stars":1,"title":"An implementation of CVE-2015-3306"},{"date":"2025-11-02T20:36:22Z","kind":"github_poc","ref":"https://github.com/cybersensei-EH/hackviser_labs_CVE-2015-3306","stars":1,"title":"This is a customized script to help solve the lab on remote code execution under the CVE-2015-3306 lab."}],"tier":"exploited"},"has_fix":true,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","indexable":true,"kev":{"dateAdded":"2026-10-08","dueDate":"2026-10-11","knownRansomwareCampaignUse":"Unknown","product":"ProFTPD","requiredAction":"Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes).
