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-2018-17953 in the wild and no public exploit code.\n\nAffected product: SUSE pam. 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-2018-17953/ (Markdown: https://insights.sbomify.com/CVE-2018-17953/index.md)","id":"CVE-2018-17953","markdown":"https://insights.sbomify.com/CVE-2018-17953/index.md","name":"CVE-2018-17953","record":{"aliases":["GHSA-wwc4-7rwv-m5ch","SUSE-SU-2018:3965-1"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux PAM module","requires_auth":"none","summary":"A bug in SUSE's PAM access module causes access rules to fail open, allowing unauthorized users to bypass authentication restrictions.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microfocus","cpe":[{"product":"linux-pam","vendor":"kernel"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"A incorrect variable in a SUSE specific patch for pam_access rule matching in PAM 1.3.0 in openSUSE Leap 15.0 and SUSE Linux Enterprise 15 could lead to pam_access rules not being applied (fail open).","ecosystems":["SUSE:Linux Enterprise Module for Basesystem 15","SUSE:Linux Enterprise Module for Development Tools 15"],"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":"pam_access does not handle netmask matches correctly","id":"CVE-2018-17953","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2018"},"n_packages":2,"n_references":1,"next":{"headline":"crowbar provision leaks admin password to all nodes in cleartext","id":"CVE-2018-17954"},"packages":[{"ecosystem":"SUSE:Linux Enterprise Module for Basesystem 15","fixed":["1.3.0-6.6.1"],"introduced":["0"],"last_affected":[],"package":"pam","purl":"pkg:rpm/suse/pam\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Basesystem%2015","source":"SUSE-SU-2018:3965-1"},{"ecosystem":"SUSE:Linux Enterprise Module for Development Tools 15","fixed":["1.3.0-6.6.1"],"introduced":["0"],"last_affected":[],"package":"pam","purl":"pkg:rpm/suse/pam\u0026distro=SUSE%20Linux%20Enterprise%20Module%20for%20Development%20Tools%2015","source":"SUSE-SU-2018:3965-1"}],"prev":{"headline":"Cross-site scripting in NetIQ eDirectory 9.1 SP2","id":"CVE-2018-17952"},"products":["pam"],"published":"2018-11-27","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":"SUSE"},{"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":"2024-09-16","vendors":["SUSE"]},"summary":"A bug in SUSE's PAM access module causes access rules to fail open, allowing unauthorized users to bypass authentication restrictions.","url":"https://insights.sbomify.com/CVE-2018-17953/"}
