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-2021-22284 in the wild and no public exploit code.\n\nAffected product: ABB 800xA, Control Software for AC 800M OPC Server for AC 800M. 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-2021-22284/ (Markdown: https://insights.sbomify.com/CVE-2021-22284/index.md)","id":"CVE-2021-22284","markdown":"https://insights.sbomify.com/CVE-2021-22284/index.md","name":"CVE-2021-22284","record":{"aliases":["GHSA-xpp9-6v93-3xvq"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ABB OPC Server","requires_auth":"low_privilege","summary":"An attacker can execute arbitrary code on the AC 800M OPC Server due to incorrect permission assignments, requiring immediate patching for industrial control systems.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ABB","cpe":[{"product":"opc_server_for_ac_800m","vendor":"abb"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"Incorrect Permission Assignment for Critical Resource vulnerability in OPC Server for AC 800M allows an attacker to execute arbitrary code in the node running the AC800M OPC Server.","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":"SECURITY - OPC Server for AC 800M - Remote Code Execution Vulnerability","id":"CVE-2021-22284","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":"Denial of service in PNI800","id":"CVE-2021-22285"},"packages":[],"prev":{"headline":"MMS File Transfer Vulnerability impact on Distribution Automation products","id":"CVE-2021-22283"},"products":["800xA, Control Software for AC 800M OPC Server for AC 800M","Compact Product Suite - Control and I/O OPC Server for AC 800M","Control Builder Safe, version 1.x OPC Server for AC 800M","Control Builder Safe, version 2.0 OPC Server for AC 800M"],"published":"2022-02-04","related":[],"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":"2024-09-16","vendors":["ABB"]},"summary":"An attacker can execute arbitrary code on the AC 800M OPC Server due to incorrect permission assignments, requiring immediate patching for industrial control systems.","url":"https://insights.sbomify.com/CVE-2021-22284/"}
