Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-45891 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-2021-45891/ (Markdown: https://insights.sbomify.com/CVE-2021-45891/index.md)","id":"CVE-2021-45891","markdown":"https://insights.sbomify.com/CVE-2021-45891/index.md","name":"CVE-2021-45891","record":{"aliases":["GHSA-rw7c-r2hj-99vq"],"analysis":{"component_type":"desktop_application","fix_type":"no_fix_stated","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"ARC application","requires_auth":"low_privilege","summary":"Attackers can escalate privileges in Softwarebuero Zauner ARC because permission checks are performed only on the client side.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"arc","vendor":"zauner"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-669","name":"Incorrect Resource Transfer Between Spheres"}],"description":"An issue was discovered in Softwarebuero Zauner ARC 4.2.0.4., that allows attackers to escalate privileges within the application, since all permission checks are done client-side, not server-side.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Missing authorization in n/a","id":"CVE-2021-45891","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Hardcoded credentials in n/a","id":"CVE-2021-45892"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2021-45890"},"products":["n/a"],"published":"2022-04-05","related":[{"cvss_score":7.5,"headline":"Security feature bypass in n/a","id":"CVE-2021-45893","kev_date_added":null,"published":"2022-04-05"},{"cvss_score":5.9,"headline":"Hardcoded credentials in n/a","id":"CVE-2021-45892","kev_date_added":null,"published":"2022-04-05"},{"cvss_score":5.9,"headline":"Information disclosure in n/a","id":"CVE-2021-45894","kev_date_added":null,"published":"2022-04-05"}],"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":"Attackers can escalate privileges in Softwarebuero Zauner ARC because permission checks are performed only on the client side.","url":"https://insights.sbomify.com/CVE-2021-45891/"}
