It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-16154 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2020-16154/ (Markdown: https://insights.sbomify.com/CVE-2020-16154/index.md)","id":"CVE-2020-16154","markdown":"https://insights.sbomify.com/CVE-2020-16154/index.md","name":"CVE-2020-16154","record":{"aliases":["DEBIAN-CVE-2020-16154","GHSA-m92x-373g-xc36","MGASA-2022-0078","UBUNTU-CVE-2020-16154","USN-5230-1","openSUSE-SU-2022:0074-1","openSUSE-SU-2024:11783-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Perl package manager","requires_auth":"none","summary":"Attackers can bypass signature verification in the App::cpanminus Perl package, potentially installing untrusted or malicious modules.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"\\","vendor":"app\\"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"The App::cpanminus package 1.7044 for Perl allows Signature Verification Bypass.","ecosystems":["SUSE:Package Hub 15 SP3","openSUSE:Leap 15.3","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":"Security feature bypass in n/a","id":"CVE-2020-16154","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"security_feature_bypass","year":"2020"},"n_packages":3,"n_references":3,"next":{"headline":"Other in n/a","id":"CVE-2020-16155"},"packages":[{"ecosystem":"SUSE:Package Hub 15 SP3","fixed":["1.7045-bp153.2.3.1"],"introduced":["0"],"last_affected":[],"package":"perl-App-cpanminus","purl":"pkg:rpm/suse/perl-App-cpanminus\u0026distro=SUSE%20Package%20Hub%2015%20SP3","source":"openSUSE-SU-2022:0074-1"},{"ecosystem":"openSUSE:Leap 15.3","fixed":["1.7045-bp153.2.3.1"],"introduced":["0"],"last_affected":[],"package":"perl-App-cpanminus","purl":"pkg:rpm/opensuse/perl-App-cpanminus\u0026distro=openSUSE%20Leap%2015.3","source":"openSUSE-SU-2022:0074-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.7045-1.1"],"introduced":["0"],"last_affected":[],"package":"perl-App-cpanminus","purl":"pkg:rpm/opensuse/perl-App-cpanminus\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:11783-1"}],"prev":{"headline":"Code injection in n/a","id":"CVE-2020-16152"},"products":["n/a"],"published":"2021-12-13","related":[{"cvss_score":9.8,"headline":"Supply chain in n/a","id":"CVE-2024-45321","kev_date_added":null,"published":"2024-08-27"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can bypass signature verification in the App::cpanminus Perl package, potentially installing untrusted or malicious modules.","url":"https://insights.sbomify.com/CVE-2020-16154/"}
