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-2021-32557 in the wild and no public exploit code.\n\nAffected product: Canonical apport. 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-2021-32557/ (Markdown: https://insights.sbomify.com/CVE-2021-32557/index.md)","id":"CVE-2021-32557","markdown":"https://insights.sbomify.com/CVE-2021-32557/index.md","name":"CVE-2021-32557","record":{"aliases":["GHSA-ggh9-6q6m-3fh2","UBUNTU-CVE-2021-32557"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Ubuntu apport","requires_auth":"low_privilege","summary":"An attacker can write arbitrary files via symlink exploitation in the apport whoopsie-upload-all script, potentially compromising system integrity.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"apport","vendor":"canonical"}],"cvss":{"score":5.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-61","name":"UNIX Symbolic Link (Symlink) Following"},{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"It was discovered that the process_report() function in data/whoopsie-upload-all allowed arbitrary file writes via symlinks.","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":"apport process_report() arbitrary file write","id":"CVE-2021-32557","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-32558"},"packages":[],"prev":{"headline":"apport get_modified_conffiles() function command injection","id":"CVE-2021-32556"},"products":["apport"],"published":"2021-06-12","related":[{"cvss_score":8.8,"headline":"apport improperly parses /proc/pid/status","id":"CVE-2021-25682","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":8.8,"headline":"apport improperly parses /proc/pid/stat","id":"CVE-2021-25683","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":8.8,"headline":"apport can be stalled by reading a FIFO","id":"CVE-2021-25684","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":7.8,"headline":"Race condition in Apport","id":"CVE-2021-3899","kev_date_added":null,"published":"2024-06-03"},{"cvss_score":7.8,"headline":"Other in Apport","id":"CVE-2022-1242","kev_date_added":null,"published":"2024-06-03"},{"cvss_score":7.7,"headline":"local privilege escalation in apport-cli","id":"CVE-2023-1326","kev_date_added":null,"published":"2023-04-13"},{"cvss_score":7.5,"headline":"Denial of service in Apport","id":"CVE-2022-28653","kev_date_added":null,"published":"2025-01-31"}],"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":"2024-09-16","vendors":["Canonical"]},"summary":"An attacker can write arbitrary files via symlink exploitation in the apport whoopsie-upload-all script, potentially compromising system integrity.","url":"https://insights.sbomify.com/CVE-2021-32557/"}
