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-2020-13881 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu 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-2020-13881/ (Markdown: https://insights.sbomify.com/CVE-2020-13881/index.md)","id":"CVE-2020-13881","markdown":"https://insights.sbomify.com/CVE-2020-13881/index.md","name":"CVE-2020-13881","record":{"aliases":["DLA-2239-1","DLA-2730-1","GHSA-gm22-vmf2-hwxg","UBUNTU-CVE-2020-13881","USN-4521-1"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Linux PAM module","requires_auth":"none","summary":"Attackers with log access can retrieve TACACS+ shared secrets if DEBUG logging is enabled in pam_tacplus.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"cloudvision_portal","vendor":"arista"},{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"pam_tacplus","vendor":"pam_tacplus_project"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-532","name":"Insertion of Sensitive Information into Log File"}],"description":"In support.c in pam_tacplus 1.3.8 through 1.5.1, the TACACS+ shared secret gets logged via syslog if the DEBUG loglevel and journald are used.","ecosystems":[],"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":"Information disclosure in n/a","id":"CVE-2020-13881","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","debian:debian_linux"],"type":"information_disclosure","year":"2020"},"n_packages":0,"n_references":7,"next":{"headline":"Race condition in n/a","id":"CVE-2020-13882"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2020-13880"},"products":["n/a"],"published":"2020-06-06","related":[{"cvss_score":8.8,"headline":"Missing authorization in n/a","id":"CVE-2016-9012","kev_date_added":null,"published":"2017-01-23"},{"cvss_score":8.1,"headline":"Missing authorization in CloudVision","id":"CVE-2023-24546","kev_date_added":null,"published":"2023-06-13"},{"cvss_score":7.8,"headline":"Missing authorization in n/a","id":"CVE-2019-18181","kev_date_added":null,"published":"2019-12-19"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2019-17596","kev_date_added":null,"published":"2019-10-24"},{"cvss_score":6.5,"headline":"Path traversal in n/a","id":"CVE-2020-24333","kev_date_added":null,"published":"2020-09-22"},{"cvss_score":6.5,"headline":"Missing authorization in n/a","id":"CVE-2018-12357","kev_date_added":null,"published":"2019-08-15"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers with log access can retrieve TACACS+ shared secrets if DEBUG logging is enabled in pam_tacplus.","url":"https://insights.sbomify.com/CVE-2020-13881/"}
