Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-35025 in the wild and no public exploit code.\n\nAffected product: ProFTPD. 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-2026-35025/ (Markdown: https://insights.sbomify.com/CVE-2026-35025/index.md)","id":"CVE-2026-35025","markdown":"https://insights.sbomify.com/CVE-2026-35025/index.md","name":"CVE-2026-35025","record":{"aliases":["DEBIAN-CVE-2026-35025","GHSA-9vr4-2f43-pc8v","UBUNTU-CVE-2026-35025"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"ProFTPD FTP server","requires_auth":"low_privilege","summary":"Authenticated users can bypass ACL restrictions to rename and retrieve files from protected directories via path manipulation in RNFR.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"proftpd","vendor":"proftpd"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"ProFTPD through 1.3.9b and 1.3.10rc2 contains an access control bypass vulnerability that allows authenticated FTP users to circumvent Directory ACL restrictions by prefixing paths with /proc/self/root in the RNFR command handler. Attackers can exploit the unresolved symlink components in dir_canonical_path() to cause dir_check() to perform lexical path comparisons that match no configured Directory block, enabling rename operations on files in DenyAll-protected directories and subsequent retrieval of those files. Mitigation: Sessions configured with DefaultRoot (chroot) are not affected, as chroot changes the directory to which /proc/self/root resolves.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"ProFTPD ACL Bypass via /proc/self/root Path Prefix in RNFR","id":"CVE-2026-35025","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2026-35026"},"packages":[],"prev":{"headline":"Wimi Teamwork On-Premises \u003c 8.2.0 IDOR via preview.php","id":"CVE-2026-35023"},"products":["ProFTPD"],"published":"2026-06-24","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2010-4221","kev_date_added":null,"published":"2010-11-09"},{"cvss_score":9.3,"headline":"ProFTPD 1.3.3c Backdoor Command Execution","id":"CVE-2010-20103","kev_date_added":null,"published":"2025-08-20"},{"cvss_score":9,"headline":"Use after free in n/a","id":"CVE-2011-4130","kev_date_added":null,"published":"2011-12-06"},{"cvss_score":8.7,"headline":"ProFTPD mod_sftp Heap Buffer Overflow via SFTP Packet Reassembly","id":"CVE-2026-63090","kev_date_added":null,"published":"2026-07-20"},{"cvss_score":8.1,"headline":"SQL injection in ProFTPD","id":"CVE-2026-42167","kev_date_added":null,"published":"2026-04-28"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2004-0346","kev_date_added":null,"published":"2004-03-18"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-14","vendors":["ProFTPD Project"]},"summary":"Authenticated users can bypass ACL restrictions to rename and retrieve files from protected directories via path manipulation in RNFR.","url":"https://insights.sbomify.com/CVE-2026-35025/"}
