An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-22676 and fix it if it is affected.\n\nWhat it is: CVE-2021-22676 is a medium-severity cross-site scripting vulnerability in WebAccess/SCADA, published on 10 Aug 2021. 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-2021-22676 in the wild and no public exploit code.\n\nAffected product: WebAccess/SCADA. 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-2021-22676/ (Markdown: https://insights.sbomify.com/CVE-2021-22676/index.md)","id":"CVE-2021-22676","markdown":"https://insights.sbomify.com/CVE-2021-22676/index.md","name":"CVE-2021-22676","record":{"aliases":["GHSA-xwfh-4h89-6h98"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"SCADA software","requires_auth":"none","summary":"Cross-site scripting in WebAccess/SCADA allows attackers to hijack sessions and redirect users via malicious JavaScript.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"webaccess\\/scada","vendor":"advantech"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"UserExcelOut.asp within WebAccess/SCADA is vulnerable to cross-site scripting (XSS), which could allow an attacker to send malicious JavaScript code.
