An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-29093 in the wild and no public exploit code.\n\nAffected product: Esri Arcgis Server. 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-2021-29093/ (Markdown: https://insights.sbomify.com/CVE-2021-29093/index.md)","id":"CVE-2021-29093","markdown":"https://insights.sbomify.com/CVE-2021-29093/index.md","name":"CVE-2021-29093","record":{"aliases":["GHSA-9rmq-v4f7-rgqg"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"GIS server software","requires_auth":"high_privilege","summary":"An authenticated attacker with specialized permissions can achieve arbitrary code execution via a use-after-free vulnerability in ArcGIS Server.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Esri","cpe":[{"product":"arcgis_server","vendor":"esri"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"A use-after-free vulnerability when parsing a specially crafted file in Esri ArcGIS Server 10.8.1 (and earlier) allows an authenticated attacker with specialized permissions to achieve arbitrary code execution in the context of the service account.","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":"ArcGIS Server image service and raster analytics security update: use-after-free","id":"CVE-2021-29093","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"esri:arcgis_server","products":["esri:arcgis_server"],"type":"use_after_free","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"ArcGIS Server image service and raster analytics security update: buffer overflow","id":"CVE-2021-29094"},"packages":[],"prev":{"headline":"File upload in Synology Photo Station","id":"CVE-2021-29092"},"products":["ArcGIS Server"],"published":"2021-03-25","related":[{"cvss_score":10,"headline":"BUG-000179884 - There is a security vulnerability in ArcGIS Server Feature Services.","id":"CVE-2025-57870","kev_date_added":null,"published":"2025-10-22"},{"cvss_score":9.8,"headline":"Directory Traversal in ArcGIS Server","id":"CVE-2026-9181","kev_date_added":null,"published":"2026-07-06"},{"cvss_score":9.8,"headline":"Unvalidated File Upload vulnerability in ArcGIS Server.","id":"CVE-2026-9182","kev_date_added":null,"published":"2026-07-06"},{"cvss_score":9.8,"headline":"Server-side request forgery in n/a","id":"CVE-2020-35712","kev_date_added":null,"published":"2020-12-25"},{"cvss_score":9.1,"headline":"There is a Server-Side Request Forgery (SSRF) vulnerability in Esri ArcGIS Server Manager version 10.8.1 and below.","id":"CVE-2021-29102","kev_date_added":null,"published":"2021-07-11"},{"cvss_score":8.7,"headline":"SQL injection vulnerability in ArcGIS Server","id":"CVE-2024-51962","kev_date_added":null,"published":"2025-03-03"},{"cvss_score":8.5,"headline":"Unauthorized access to secure services in ArcGIS Server","id":"CVE-2024-51954","kev_date_added":null,"published":"2025-03-03"}],"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":["Esri"]},"summary":"An authenticated attacker with specialized permissions can achieve arbitrary code execution via a use-after-free vulnerability in ArcGIS Server.","url":"https://insights.sbomify.com/CVE-2021-29093/"}
