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-2020-5853 in the wild and no public exploit code.\n\nAffected product: F5 Big-Ip Access Policy Manager. 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-2020-5853/ (Markdown: https://insights.sbomify.com/CVE-2020-5853/index.md)","id":"CVE-2020-5853","markdown":"https://insights.sbomify.com/CVE-2020-5853/index.md","name":"CVE-2020-5853","record":{"aliases":["GHSA-7mwx-h8w3-g965"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"BIG-IP APM","requires_auth":"low_privilege","summary":"Attackers can inject malicious JavaScript via backend servers to cause name conflicts in BIG-IP APM portal access, potentially compromising session integrity.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"f5","cpe":[{"product":"big-ip_access_policy_manager","vendor":"f5"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"In BIG-IP APM portal access on versions 15.0.0-15.1.0, 14.0.0-14.1.2.3, 13.1.0-13.1.3.2, 12.1.0-12.1.5, and 11.5.2-11.6.5.1, when backend servers serve HTTP pages with special JavaScript code, this can lead to internal portal access name conflict.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cross-site scripting in BIG-IP APM","id":"CVE-2020-5853","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"f5:big-ip_access_policy_manager","products":["f5:big-ip_access_policy_manager"],"type":"xss","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in BIG-IP","id":"CVE-2020-5854"},"packages":[],"prev":{"headline":"Denial of service in BIG-IP","id":"CVE-2020-5852"},"products":["BIG-IP APM"],"published":"2020-01-14","related":[{"cvss_score":9.8,"headline":"F5 BIG-IP Configuration Utility Authentication Bypass","id":"CVE-2023-46747","kev_date_added":"2023-10-31","published":"2023-10-26"},{"cvss_score":9.8,"headline":"F5 BIG-IP Missing Authentication","id":"CVE-2022-1388","kev_date_added":"2022-05-10","published":"2022-05-05"},{"cvss_score":9.8,"headline":"F5 BIG-IP and BIG-IQ Centralized Management iControl REST Remote Code Execution","id":"CVE-2021-22986","kev_date_added":"2021-11-03","published":"2021-03-31"},{"cvss_score":9.8,"headline":"F5 BIG-IP Traffic Management Microkernel Buffer Overflow","id":"CVE-2021-22991","kev_date_added":"2022-01-18","published":"2021-03-31"},{"cvss_score":9.8,"headline":"F5 BIG-IP Traffic Management User Interface (TMUI) Remote Code Execution","id":"CVE-2020-5902","kev_date_added":"2021-11-03","published":"2020-07-01"},{"cvss_score":9.3,"headline":"F5 BIG-IP APM Heap-based Buffer Overflow","id":"CVE-2026-94127","kev_date_added":"2026-09-22","published":"2026-09-22"},{"cvss_score":9.3,"headline":"F5 BIG-IP Stack-Based Buffer Overflow","id":"CVE-2025-53521","kev_date_added":"2026-03-27","published":"2025-10-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["F5"]},"summary":"Attackers can inject malicious JavaScript via backend servers to cause name conflicts in BIG-IP APM portal access, potentially compromising session integrity.","url":"https://insights.sbomify.com/CVE-2020-5853/"}
