Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-12021 in the wild and no public exploit code.\n\nAffected product: OSIsoft PI Web API 2019. 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-2020-12021/ (Markdown: https://insights.sbomify.com/CVE-2020-12021/index.md)","id":"CVE-2020-12021","markdown":"https://insights.sbomify.com/CVE-2020-12021/index.md","name":"CVE-2020-12021","record":{"aliases":["GHSA-q4j7-8h9j-7jxq"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Web API","requires_auth":"low_privilege","summary":"An attacker can execute arbitrary code via cross-site scripting in OSIsoft PI Web API, impacting industrial control system security.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"pi_web_api","vendor":"osisoft"}],"cvss":{"score":9,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"In OSIsoft PI Web API 2019 Patch 1 (1.12.0.6346) and all previous versions, the affected product is vulnerable to a cross-site scripting attack, which may allow an attacker to remotely execute arbitrary code.","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":"Cross-site scripting in OSIsoft PI Web API 2019","id":"CVE-2020-12021","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Code injection in Advantech WebAccess Node","id":"CVE-2020-12022"},"packages":[],"prev":{"headline":"Privilege escalation in Baxter ExactaMix EM 2400 \u0026 EM 1200","id":"CVE-2020-12020"},"products":["OSIsoft PI Web API 2019"],"published":"2020-06-23","related":[{"cvss_score":8.8,"headline":"Cross-site request forgery in OSIsoft PI Web API","id":"CVE-2019-13516","kev_date_added":null,"published":"2019-08-15"},{"cvss_score":8.8,"headline":"Cross-site request forgery in OSIsoft PI Web API 2017","id":"CVE-2017-7926","kev_date_added":null,"published":"2017-08-25"},{"cvss_score":6.9,"headline":"OSIsoft PI Web API","id":"CVE-2021-43549","kev_date_added":null,"published":"2021-11-18"},{"cvss_score":6.5,"headline":"Information disclosure in OSIsoft PI Web API","id":"CVE-2019-13515","kev_date_added":null,"published":"2019-08-15"}],"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":["n/a"]},"summary":"An attacker can execute arbitrary code via cross-site scripting in OSIsoft PI Web API, impacting industrial control system security.","url":"https://insights.sbomify.com/CVE-2020-12021/"}
