An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2000-1221 exists.\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-2000-1221/ (Markdown: https://insights.sbomify.com/CVE-2000-1221/index.md)","id":"CVE-2000-1221","markdown":"https://insights.sbomify.com/CVE-2000-1221/index.md","name":"CVE-2000-1221","record":{"aliases":["DEBIAN-CVE-2000-1221","GHSA-7g6p-865f-j3r5"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux lpr daemon","requires_auth":"none","summary":"Remote attackers can bypass lpd access controls by manipulating DNS reverse resolution to spoof the local hostname, allowing unauthorized print job submission.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux","vendor":"redhat"},{"product":"irix","vendor":"sgi"}],"cvss":{"score":10,"severity":"critical","source":"nvd","vector":"AV:N/AC:L/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[],"description":"The line printer daemon (lpd) in the lpr package in multiple Linux operating systems authenticates by comparing the reverse-resolved hostname of the local machine to the hostname of the print server as returned by gethostname, which allows remote attackers to bypass intended access controls by modifying the DNS for the attacking IP.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2000-01-11","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2000-01-11","kind":"exploitdb","ref":"19722","stars":null,"title":"RedHat 6.1 / IRIX 6.5.18 - 'lpd' Command Execution"}],"tier":"weaponised"},"has_fix":true,"headline":"Auth bypass in n/a","id":"CVE-2000-1221","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","redhat:linux","sgi:irix"],"type":"auth_bypass","year":"2000"},"n_packages":0,"n_references":8,"next":{"headline":"Path traversal in n/a","id":"CVE-2000-1222"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2000-1220"},"products":["n/a"],"published":"2005-04-21","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-08","vendors":["n/a"]},"summary":"Remote attackers can bypass lpd access controls by manipulating DNS reverse resolution to spoof the local hostname, allowing unauthorized print job submission.","url":"https://insights.sbomify.com/CVE-2000-1221/"}
