An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-6687 in the wild and no public exploit code.\n\nAffected product: F5 Big-Ip Application Security 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-2019-6687/ (Markdown: https://insights.sbomify.com/CVE-2019-6687/index.md)","id":"CVE-2019-6687","markdown":"https://insights.sbomify.com/CVE-2019-6687/index.md","name":"CVE-2019-6687","record":{"aliases":["GHSA-33c8-c6vf-6wgg"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"BIG-IP ASM","requires_auth":"none","summary":"F5 BIG-IP ASM fails to properly authenticate remote X.509 certificates, allowing attackers to bypass security controls.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"f5","cpe":[{"product":"big-ip_application_security_manager","vendor":"f5"}],"cvss":{"score":7.4,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"On versions 15.0.0-15.0.1.1, the BIG-IP ASM Cloud Security Services profile uses a built-in verification mechanism that fails to properly authenticate the X.509 certificate of remote endpoints.","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":"Weak cryptography in BIG-IP ASM","id":"CVE-2019-6687","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"f5:big-ip_application_security_manager","products":["f5:big-ip_application_security_manager"],"type":"weak_cryptography","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in BIG-IP","id":"CVE-2019-6688"},"packages":[],"prev":{"headline":"Denial of service in BIG-IP","id":"CVE-2019-6686"},"products":["BIG-IP ASM"],"published":"2019-12-23","related":[{"cvss_score":9.4,"headline":"Other in BIG-IP ASM","id":"CVE-2019-6665","kev_date_added":null,"published":"2019-11-27"},{"cvss_score":9.1,"headline":"Information disclosure in BIG-IP ASM","id":"CVE-2019-6650","kev_date_added":null,"published":"2019-09-20"},{"cvss_score":8.9,"headline":"BIG-IP Advanced WAF/ASM BADoS vulnerability","id":"CVE-2025-24326","kev_date_added":null,"published":"2025-02-05"},{"cvss_score":8.7,"headline":"BIG-IP HTTP/2 vulnerability","id":"CVE-2025-55669","kev_date_added":null,"published":"2025-10-15"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2009-4420","kev_date_added":null,"published":"2009-12-24"},{"cvss_score":7.5,"headline":"Denial of service in BIG-IP ASM/Advanced WAF","id":"CVE-2021-23010","kev_date_added":null,"published":"2021-05-10"},{"cvss_score":7.5,"headline":"Denial of service in BIG-IP APM","id":"CVE-2021-22985","kev_date_added":null,"published":"2021-02-12"}],"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":"F5 BIG-IP ASM fails to properly authenticate remote X.509 certificates, allowing attackers to bypass security controls.","url":"https://insights.sbomify.com/CVE-2019-6687/"}
