It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2020-28949 and fix it if it is affected.\n\nWhat it is: CVE-2020-28949 is a high-severity path traversal vulnerability in Debian Debian Linux, published on 19 Nov 2020. 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: Yes. Attackers have exploited CVE-2020-28949 in the wild since at least 25 Aug 2022.\n\nAffected product: Debian Debian 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-2020-28949/ (Markdown: https://insights.sbomify.com/CVE-2020-28949/index.md)","id":"CVE-2020-28949","markdown":"https://insights.sbomify.com/CVE-2020-28949/index.md","name":"CVE-2020-28949","record":{"aliases":["CLEANSTART-2024-ZN01309","DEBIAN-CVE-2020-28949","UBUNTU-CVE-2020-28949"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PHP Archive_Tar library","requires_auth":"none","summary":"Attackers can overwrite arbitrary files via stream wrapper attacks in the Archive_Tar library due to insufficient filename sanitization.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"drupal","vendor":"drupal"},{"product":"fedora","vendor":"fedoraproject"},{"product":"archive_tar","vendor":"php"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"Archive_Tar through 1.4.10 has :// filename sanitization only to address phar attacks, and thus any other stream-wrapper attack (such as file:// to overwrite files) can still succeed.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2020-11-17","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2020-11-17","kind":"metasploit","ref":"exploit/multi/fileformat/archive_tar_arb_file_write","stars":null,"title":"PEAR Archive_Tar 1.4.10 Arbitrary File Write"}],"tier":"exploited"},"has_fix":true,"headline":"PEAR Archive_Tar Deserialization of Untrusted Data","id":"CVE-2020-28949","indexable":true,"kev":{"dateAdded":"2022-08-25","dueDate":"2022-09-15","knownRansomwareCampaignUse":"Unknown","product":"Archive_Tar","requiredAction":"Apply updates per vendor instructions.","vendorProject":"PEAR","vulnerabilityName":"PEAR Archive_Tar Deserialization of Untrusted Data Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","drupal:drupal","fedoraproject:fedora"],"type":"path_traversal","year":"2020"},"n_packages":0,"n_references":12,"next":{"headline":"Privilege escalation in Kaspersky Anti-Ransomware Tool","id":"CVE-2020-28950"},"packages":[],"prev":{"headline":"Deserialization in n/a","id":"CVE-2020-28948"},"products":["n/a"],"published":"2020-11-19","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["n/a"]},"summary":"Attackers can overwrite arbitrary files via stream wrapper attacks in the Archive_Tar library due to insufficient filename sanitization.","url":"https://insights.sbomify.com/CVE-2020-28949/"}
