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: There is no known exploitation of CVE-2023-5524 in the wild and no public exploit code.\n\nAffected product: M-Files Web Companion. 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-2023-5524/ (Markdown: https://insights.sbomify.com/CVE-2023-5524/index.md)","id":"CVE-2023-5524","markdown":"https://insights.sbomify.com/CVE-2023-5524/index.md","name":"CVE-2023-5524","record":{"aliases":["GHSA-r2vj-428g-v68v"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"M-Files Web Companion","requires_auth":"low_privilege","summary":"Insufficient file type blacklisting in M-Files Web Companion allows attackers to achieve remote code execution by uploading specific malicious files.","user_interaction":"required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"M-Files Corporation","cpe":[{"product":"web_companion","vendor":"m-files"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Insufficient blacklisting in M-Files Web Companion before release version 23.10 and LTS Service Release Versions before 23.8 LTS SR1 allows \n\nRemote Code Execution\n\n via specific file types","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":"M-Files Web Companion allows Remote Code Execution for some filetypes","id":"CVE-2023-5524","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Limit Login Attempts Reloaded \u003c 2.25.26 - Admin+ Missing Authorization to Toggle Plugin Auto-Update","id":"CVE-2023-5525"},"packages":[],"prev":{"headline":"M-Files Web Companion allows Remote Code Execution","id":"CVE-2023-5523"},"products":["Web Companion"],"published":"2023-10-20","related":[{"cvss_score":8.6,"headline":"M-Files Web Companion allows Remote Code Execution","id":"CVE-2023-5523","kev_date_added":null,"published":"2023-10-20"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-23","vendors":["M-Files"]},"summary":"Insufficient file type blacklisting in M-Files Web Companion allows attackers to achieve remote code execution by uploading specific malicious files.","url":"https://insights.sbomify.com/CVE-2023-5524/"}
