An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-34764 and fix it if it is affected.\n\nWhat it is: CVE-2021-34764 is a medium-severity cross-site scripting vulnerability in Cisco Secure Firewall Threat Defense, published on 27 Oct 2021. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-34764 in the wild and no public exploit code.\n\nAffected product: Cisco Secure Firewall Threat Defense. 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-2021-34764/ (Markdown: https://insights.sbomify.com/CVE-2021-34764/index.md)","id":"CVE-2021-34764","markdown":"https://insights.sbomify.com/CVE-2021-34764/index.md","name":"CVE-2021-34764","record":{"aliases":["GHSA-29vr-6hw6-5v65"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Firepower Management Center","requires_auth":"high_privilege","summary":"Attackers can execute cross-site scripting or open redirect attacks in the Cisco Firepower Management Center web interface.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"firepower_management_center_virtual_appliance","vendor":"cisco"},{"product":"secure_firewall_threat_defense","vendor":"cisco"},{"product":"sourcefire_defense_center","vendor":"cisco"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/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"},{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"Multiple vulnerabilities in the web-based management interface of Cisco Firepower Management Center (FMC) Software could allow an attacker to execute a cross-site scripting (XSS) attack or an open redirect attack.
