An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-15781 in the wild and no public exploit code.\n\nAffected product: Siemens AG SICAM WEB firmware for SICAM A8000 RTUs. 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-2020-15781/ (Markdown: https://insights.sbomify.com/CVE-2020-15781/index.md)","id":"CVE-2020-15781","markdown":"https://insights.sbomify.com/CVE-2020-15781/index.md","name":"CVE-2020-15781","record":{"aliases":["GHSA-rx5g-mw23-2hw2"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"SICAM A8000 RTU","requires_auth":"none","summary":"An attacker can inject malicious scripts into log messages via the login screen, which execute when viewed by a victim in the web interface.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"sicam_a8000_firmware","vendor":"siemens"}],"cvss":{"score":9.6,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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":"A vulnerability has been identified in SICAM WEB firmware for SICAM A8000 RTUs (All versions \u003c V05.30).
