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-2021-26726 in the wild and no public exploit code.\n\nAffected product: Valmet DNA. 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-2021-26726/ (Markdown: https://insights.sbomify.com/CVE-2021-26726/index.md)","id":"CVE-2021-26726","markdown":"https://insights.sbomify.com/CVE-2021-26726/index.md","name":"CVE-2021-26726","record":{"aliases":["GHSA-f4vp-f6h9-8cx8"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Valmet DNA","requires_auth":"none","summary":"Attackers can execute arbitrary commands with SYSTEM privileges on Valmet DNA systems via a service listening on TCP port 1517.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Nozomi","cpe":[{"product":"dna","vendor":"valmet"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-330","name":"Use of Insufficiently Random Values"},{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-305","name":"Authentication Bypass by Primary Weakness"},{"id":"CWE-272","name":"Least Privilege Violation"},{"id":"CWE-209","name":"Generation of Error Message Containing Sensitive Information"}],"description":"A remote code execution vulnerability affecting a Valmet DNA service listening on TCP port 1517, allows an attacker to execute commands with SYSTEM privileges This issue affects: Valmet DNA versions from Collection 2012 until Collection 2021.","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":"Remote code execution in Valmet DNA before Collection 2021","id":"CVE-2021-26726","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"spx_restservice SubNet_handler_func Multiple Command Injections and Stack-Based Buffer Overflows","id":"CVE-2021-26727"},"packages":[],"prev":{"headline":"Authenticated command path traversal on timezone settings in Guardian/CMC before 20.0.7.4","id":"CVE-2021-26725"},"products":["Valmet DNA"],"published":"2022-02-16","related":[{"cvss_score":8.7,"headline":"Valmet DNA Web server arbitrary file read access","id":"CVE-2025-15577","kev_date_added":null,"published":"2026-02-12"}],"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":["Valmet DNA"]},"summary":"Attackers can execute arbitrary commands with SYSTEM privileges on Valmet DNA systems via a service listening on TCP port 1517.","url":"https://insights.sbomify.com/CVE-2021-26726/"}
