An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-27254 and fix it if it is affected.\n\nWhat it is: CVE-2020-27254 is a high-severity authentication bypass vulnerability in Emerson Rosemount X-STREAM Gas Analyzer, published on 21 Dec 2020. 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-2020-27254 in the wild and no public exploit code.\n\nAffected product: Emerson Rosemount X-STREAM Gas Analyzer. 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-2020-27254/ (Markdown: https://insights.sbomify.com/CVE-2020-27254/index.md)","id":"CVE-2020-27254","markdown":"https://insights.sbomify.com/CVE-2020-27254/index.md","name":"CVE-2020-27254","record":{"aliases":["GHSA-3qjx-hh6f-4fvq"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Gas Analyzer","requires_auth":"none","summary":"An attacker can access sensitive log and backup data via a crafted URL due to improper authentication in Emerson Rosemount X-STREAM Gas Analyzers.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"x-stream_enhanced_xefd_firmware","vendor":"emerson"},{"product":"x-stream_enhanced_xegk_firmware","vendor":"emerson"},{"product":"x-stream_enhanced_xegp_firmware","vendor":"emerson"},{"product":"x-stream_enhanced_xexf_firmware","vendor":"emerson"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Emerson Rosemount X-STREAM Gas AnalyzerX-STREAM enhanced XEGP, XEGK, XEFD, XEXF – all revisions, The affected products are vulnerable to improper authentication for accessing log and backup data, which could allow an attacker with a specially crafted URL to obtain access to sensitive information.","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":"Auth bypass in Emerson Rosemount X-STREAM Gas Analyzer","id":"CVE-2020-27254","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in FactoryTalk Linx","id":"CVE-2020-27255"},"packages":[],"prev":{"headline":"Denial of service in FactoryTalk Linx","id":"CVE-2020-27253"},"products":["Emerson Rosemount X-STREAM Gas Analyzer"],"published":"2020-12-21","related":[{"cvss_score":9.8,"headline":"File upload in Emerson Rosemount X-STREAM Gas Analyzer","id":"CVE-2021-27459","kev_date_added":null,"published":"2021-05-20"},{"cvss_score":7.5,"headline":"Weak cryptography in Emerson Rosemount X-STREAM Gas Analyzer","id":"CVE-2021-27457","kev_date_added":null,"published":"2021-05-20"},{"cvss_score":7.5,"headline":"Path traversal in Emerson Rosemount X-STREAM Gas Analyzer","id":"CVE-2021-27461","kev_date_added":null,"published":"2021-05-20"},{"cvss_score":6.1,"headline":"Cross-site scripting in Emerson Rosemount X-STREAM Gas Analyzer","id":"CVE-2021-27465","kev_date_added":null,"published":"2021-05-20"},{"cvss_score":6.1,"headline":"Cross-site request forgery in Emerson Rosemount X-STREAM Gas Analyzer","id":"CVE-2021-27467","kev_date_added":null,"published":"2021-05-20"},{"cvss_score":5.3,"headline":"Information disclosure in Emerson Rosemount X-STREAM Gas Analyzer","id":"CVE-2021-27463","kev_date_added":null,"published":"2021-05-20"}],"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 access sensitive log and backup data via a crafted URL due to improper authentication in Emerson Rosemount X-STREAM Gas Analyzers.","url":"https://insights.sbomify.com/CVE-2020-27254/"}
