An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-8475 in the wild and no public exploit code.\n\nAffected product: ABB  Ability™ SCADAvantage. 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-2020-8475/ (Markdown: https://insights.sbomify.com/CVE-2020-8475/index.md)","id":"CVE-2020-8475","markdown":"https://insights.sbomify.com/CVE-2020-8475/index.md","name":"CVE-2020-8475","record":{"aliases":["GHSA-wfh9-g9j2-x793"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ABB Central Licensing System","requires_auth":"none","summary":"An attacker can block license handling in ABB Central Licensing Server by sending specially crafted messages, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ABB","cpe":[{"product":"800xa_system","vendor":"abb"},{"product":"compact_hmi","vendor":"abb"},{"product":"control_builder_safe","vendor":"abb"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"For the Central Licensing Server component used in ABB products ABB Ability™ System 800xA and related system extensions versions 5.1, 6.0 and 6.1, Compact HMI versions 5.1 and 6.0, Control Builder Safe 1.0, 1.1 and 2.0, Symphony Plus -S+ Operations 3.0 to 3.2 Symphony Plus -S+ Engineering 1.1 to 2.2, Composer Harmony 5.1, 6.0 and 6.1, Melody Composer 5.3, 6.1/6.2 and SPE for Melody 1.0SPx (Composer 6.3), Harmony OPC Server (HAOPC) Standalone 6.0, 6.1 and 7.0, ABB Ability™ System 800xA/ Advant® OCS Control Builder A 1.3 and 1.4, Advant® OCS AC100 OPC Server 5.1, 6.0 and 6.1, Composer CTK 6.1 and 6.2, AdvaBuild 3.7 SP1 and SP2, OPCServer for MOD 300 (non-800xA) 1.4, OPC Data Link 2.1 and 2.2, Knowledge Manager 8.0, 9.0 and 9.1, Manufacturing Operations Management 1812 and 1909, ABB AbilityTM SCADAvantage versions 5.1 to 5.6.5, a weakness in validation of input exists that allows an attacker to block license handling by sending specially crafted messages to the CLS web service.","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":"ABB Central Licensing System - Denial of Service Vulnerability","id":"CVE-2020-8475","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"ABB Central Licensing System - Elevation of Privilege Vulnerability","id":"CVE-2020-8476"},"packages":[],"prev":{"headline":"ABB System 800xA Weak Registry Permissions","id":"CVE-2020-8474"},"products":["ABB  Ability™ SCADAvantage","ABB Ability System 800xA","AdvaBuild","Advant  OCS AC 100 OPS Server","Advant OCS Control Builder A","Central Licensing System","Compact HMI","Composer CTK","Composer Harmony","Composer Melody","Control Builder Safe","Harmony OPC Server Standalone","Knowledge Manager","Manufacturing Operations Management","OPC Data Link","OPC Server for Mod 300 (non-800xA)","Symphony Plus S+ Engineering","Symphony Plus S+ Operations"],"published":"2020-04-29","related":[{"cvss_score":9.8,"headline":"ABB Central Licensing System - Information disclosure","id":"CVE-2020-8481","kev_date_added":null,"published":"2020-04-29"},{"cvss_score":9.4,"headline":"ABB Central Licensing System - XML External Entity Injection","id":"CVE-2020-8479","kev_date_added":null,"published":"2020-04-29"},{"cvss_score":7.8,"headline":"ABB Central Licensing System - Weak File Permissions","id":"CVE-2020-8471","kev_date_added":null,"published":"2020-04-29"},{"cvss_score":5.3,"headline":"ABB Central Licensing System - Elevation of Privilege Vulnerability","id":"CVE-2020-8476","kev_date_added":null,"published":"2020-04-29"}],"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":"2024-08-04","vendors":["ABB"]},"summary":"An attacker can block license handling in ABB Central Licensing Server by sending specially crafted messages, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2020-8475/"}
