An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-27457 and fix it if it is affected.\n\nWhat it is: CVE-2021-27457 is a high-severity vulnerability in Emerson Rosemount X-STREAM Gas Analyzer, published on 20 May 2021. 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-2021-27457 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-2021-27457/ (Markdown: https://insights.sbomify.com/CVE-2021-27457/index.md)","id":"CVE-2021-27457","markdown":"https://insights.sbomify.com/CVE-2021-27457/index.md","name":"CVE-2021-27457","record":{"aliases":["GHSA-837h-j995-v8pg"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Gas Analyzer","requires_auth":"none","summary":"Weak encryption in Emerson Rosemount X-STREAM Gas Analyzer allows attackers to easily obtain stored credentials, potentially leading to unauthorized access.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"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-327","name":"Use of a Broken or Risky Cryptographic Algorithm"},{"id":"CWE-326","name":"Inadequate Encryption Strength"}],"description":"A vulnerability has been found in multiple revisions of Emerson Rosemount X-STREAM Gas Analyzer.
