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-2021-27448 in the wild and no public exploit code.\n\nAffected product: MU320E. 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-2021-27448/ (Markdown: https://insights.sbomify.com/CVE-2021-27448/index.md)","id":"CVE-2021-27448","markdown":"https://insights.sbomify.com/CVE-2021-27448/index.md","name":"CVE-2021-27448","record":{"aliases":["GHSA-355w-35c4-fwh9"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"MU320E firmware","requires_auth":"low_privilege","summary":"Adversaries with local access can escalate privileges on the MU320E due to a file system miscommunication, requiring a firmware upgrade.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"mu320e_firmware","vendor":"ge"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"},{"id":"CWE-250","name":"Execution with Unnecessary Privileges"}],"description":"A miscommunication in the file system allows adversaries with access to the MU320E to escalate privileges on the MU320E (all firmware versions prior to v04A00.1).","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":"Privilege escalation in MU320E","id":"CVE-2021-27448","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Mesa Labs AmegaView Command Injection","id":"CVE-2021-27449"},"packages":[],"prev":{"headline":"Mesa Labs AmegaView command injection","id":"CVE-2021-27447"},"products":["MU320E"],"published":"2021-03-25","related":[{"cvss_score":7.8,"headline":"Weak cryptography in MU320E","id":"CVE-2021-27450","kev_date_added":null,"published":"2021-03-25"},{"cvss_score":7.8,"headline":"Hardcoded credentials in MU320E","id":"CVE-2021-27452","kev_date_added":null,"published":"2021-03-25"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"Adversaries with local access can escalate privileges on the MU320E due to a file system miscommunication, requiring a firmware upgrade.","url":"https://insights.sbomify.com/CVE-2021-27448/"}
