It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-15709 in the wild and no public exploit code.\n\nAffected product: Canonical add-apt-repository. 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-2020-15709/ (Markdown: https://insights.sbomify.com/CVE-2020-15709/index.md)","id":"CVE-2020-15709","markdown":"https://insights.sbomify.com/CVE-2020-15709/index.md","name":"CVE-2020-15709","record":{"aliases":["DEBIAN-CVE-2020-15709","DLA-2339-1","GHSA-9gjg-6646-fqxh","UBUNTU-CVE-2020-15709","USN-4457-1","USN-4457-2"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Ubuntu add-apt-repository","requires_auth":"low_privilege","summary":"PPA owners can inject ANSI escape codes into terminal output via add-apt-repository, potentially modifying terminal contents unexpectedly.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"add-apt-repository","vendor":"canonical"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Versions of add-apt-repository before 0.98.9.2, 0.96.24.32.14, 0.96.20.10, and 0.92.37.8ubuntu0.1~esm1, printed a PPA (personal package archive) description to the terminal as-is, which allowed PPA owners to provide ANSI terminal escapes to modify terminal contents in unexpected ways.","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":"add-apt-repository print ASNI terminal codes","id":"CVE-2020-15709","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Potential double-free in pulseaudio","id":"CVE-2020-15710"},"packages":[],"prev":{"headline":"Libvirt Service Arbitrary File Write Privilege Escalation Vulnerability","id":"CVE-2020-15708"},"products":["add-apt-repository"],"published":"2020-09-05","related":[],"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":"2024-09-17","vendors":["Canonical"]},"summary":"PPA owners can inject ANSI escape codes into terminal output via add-apt-repository, potentially modifying terminal contents unexpectedly.","url":"https://insights.sbomify.com/CVE-2020-15709/"}
