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-2011-4407 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-2011-4407/ (Markdown: https://insights.sbomify.com/CVE-2011-4407/index.md)","id":"CVE-2011-4407","markdown":"https://insights.sbomify.com/CVE-2011-4407/index.md","name":"CVE-2011-4407","record":{"aliases":["DEBIAN-CVE-2011-4407","GHSA-m49h-wwcv-rf5m"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Ubuntu Software Properties","requires_auth":"none","summary":"Man-in-the-middle attackers can spoof GPG keys for package repositories by bypassing certificate validation in Software Properties, potentially leading to malicious code execution.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"software-properties","vendor":"canonical"},{"product":"ubuntu_linux","vendor":"canonical"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:P/A:N","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"ppa.py in Software Properties before 0.81.13.3 does not validate the server certificate when downloading PPA GPG key fingerprints, which allows man-in-the-middle (MITM) attackers to spoof GPG keys for a package repository.","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":"Security feature bypass in n/a","id":"CVE-2011-4407","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux"],"type":"security_feature_bypass","year":"2011"},"n_packages":0,"n_references":2,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2011-4408"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2011-4406"},"products":["n/a"],"published":"2014-05-14","related":[{"cvss_score":6.8,"headline":"software-properties incorrectly validated TLS certificates","id":"CVE-2012-0955","kev_date_added":null,"published":"2020-12-02"}],"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":"2024-08-07","vendors":["n/a"]},"summary":"Man-in-the-middle attackers can spoof GPG keys for package repositories by bypassing certificate validation in Software Properties, potentially leading to malicious code execution.","url":"https://insights.sbomify.com/CVE-2011-4407/"}
