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-2020-28638 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-28638/ (Markdown: https://insights.sbomify.com/CVE-2020-28638/index.md)","id":"CVE-2020-28638","markdown":"https://insights.sbomify.com/CVE-2020-28638/index.md","name":"CVE-2020-28638","record":{"aliases":["DEBIAN-CVE-2020-28638","GHSA-7796-9c37-q364","UBUNTU-CVE-2020-28638"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Tomb encryption tool","requires_auth":"none","summary":"Tomb may encrypt files with a predictable warning string as the key when pinentry-curses is used with a display, allowing unauthorized data access.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tomb","vendor":"dyne"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"ask_password in Tomb 2.0 through 2.7 returns a warning when pinentry-curses is used and $DISPLAY is non-empty, causing affected users' files to be encrypted with \"tomb {W] Detected DISPLAY, but only pinentry-curses is found.\" as the encryption key.","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":"Weak cryptography in n/a","id":"CVE-2020-28638","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in n/a","id":"CVE-2020-28641"},"packages":[],"prev":{"headline":"Memory corruption in CGAL","id":"CVE-2020-28636"},"products":["n/a"],"published":"2020-11-13","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":"2024-08-04","vendors":["n/a"]},"summary":"Tomb may encrypt files with a predictable warning string as the key when pinentry-curses is used with a display, allowing unauthorized data access.","url":"https://insights.sbomify.com/CVE-2020-28638/"}
