An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-7143 in the wild and no public exploit code.\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-2016-7143/ (Markdown: https://insights.sbomify.com/CVE-2016-7143/index.md)","id":"CVE-2016-7143","markdown":"https://insights.sbomify.com/CVE-2016-7143/index.md","name":"CVE-2016-7143","record":{"aliases":["DSA-3661-1","GHSA-fr2x-9vgp-crvv","UBUNTU-CVE-2016-7143","openSUSE-SU-2024:10220-1","openSUSE-SU-2024:11392-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"IRC server software","requires_auth":"none","summary":"Remote attackers can spoof certificate fingerprints to log in as another user in Charybdis IRC servers.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"charybdis","vendor":"charybdis_project"},{"product":"debian_linux","vendor":"debian"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"}],"description":"The m_authenticate function in modules/m_sasl.c in Charybdis before 3.5.3 allows remote attackers to spoof certificate fingerprints and consequently log in as another user via a crafted AUTHENTICATE parameter.","ecosystems":["openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Auth bypass in n/a","id":"CVE-2016-7143","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux"],"type":"auth_bypass","year":"2016"},"n_packages":2,"n_references":6,"next":{"headline":"Auth bypass in n/a","id":"CVE-2016-7144"},"packages":[{"ecosystem":"openSUSE:Tumbleweed","fixed":["3.5.3-2.1"],"introduced":["0"],"last_affected":[],"package":"charybdis","purl":"pkg:rpm/opensuse/charybdis\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:10220-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["0~ch448-1.4"],"introduced":["0"],"last_affected":[],"package":"solanum","purl":"pkg:rpm/opensuse/solanum\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:11392-1"}],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2016-7142"},"products":["n/a"],"published":"2016-09-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can spoof certificate fingerprints to log in as another user in Charybdis IRC servers.","url":"https://insights.sbomify.com/CVE-2016-7143/"}
