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-2021-35493 in the wild and no public exploit code.\n\nAffected product: TIBCO WebFOCUS Client. 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-2021-35493/ (Markdown: https://insights.sbomify.com/CVE-2021-35493/index.md)","id":"CVE-2021-35493","markdown":"https://insights.sbomify.com/CVE-2021-35493/index.md","name":"CVE-2021-35493","record":{"aliases":["GHSA-3782-4pq4-qwj2"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"TIBCO WebFOCUS","requires_auth":"low_privilege","summary":"Low-privileged attackers can execute scripts on victims' systems via stored and reflected XSS in TIBCO WebFOCUS components, requiring user interaction.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tibco","cpe":[{"product":"webfocus_client","vendor":"tibco"},{"product":"webfocus_installer","vendor":"tibco"},{"product":"webfocus_reporting_server","vendor":"tibco"}],"cvss":{"score":9,"severity":"critical","source":"cna","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":"The WebFOCUS Reporting Server and WebFOCUS Client components of TIBCO Software Inc.'s TIBCO WebFOCUS Client, TIBCO WebFOCUS Installer, and TIBCO WebFOCUS Reporting Server contain easily exploitable Stored and Reflected Cross Site Scripting (XSS) vulnerabilities that allow a low privileged attacker to social engineer a legitimate user with network access to execute scripts targeting the affected system or the victim's local system.
