Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-15326 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-2018-15326/ (Markdown: https://insights.sbomify.com/CVE-2018-15326/index.md)","id":"CVE-2018-15326","markdown":"https://insights.sbomify.com/CVE-2018-15326/index.md","name":"CVE-2018-15326","record":{"aliases":["GHSA-9mcj-x8ch-2c4c"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"BIG-IP APM","requires_auth":"low_privilege","summary":"Attackers can bypass certificate revocation checks in BIG-IP APM when CRL downloads fail, allowing revoked certificates to be treated as valid.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"f5","cpe":[{"product":"big-ip_access_policy_manager","vendor":"f5"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"In some situations on BIG-IP APM 14.0.0-14.0.0.2, 13.0.0-13.1.0.7, 12.1.0-12.1.3.5, or 11.6.0-11.6.3.2, the CRLDP Auth access policy agent may treat revoked certificates as valid when the BIG-IP APM system fails to download a new Certificate Revocation List.","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":"Security feature bypass in BIG-IP (APM)","id":"CVE-2018-15326","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"f5:big-ip_access_policy_manager","products":["f5:big-ip_access_policy_manager"],"type":"security_feature_bypass","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Missing authorization in BIG-IP (LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, FPS, GTM, Link Controller, PEM, WebAccelerator), Enterprise Manager","id":"CVE-2018-15327"},"packages":[],"prev":{"headline":"Denial of service in BIG-IP (LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, FPS, GTM, Link Controller, PEM, WebAccelerator)","id":"CVE-2018-15325"},"products":["BIG-IP (APM)"],"published":"2018-10-31","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":"2024-08-05","vendors":["F5 Networks, Inc."]},"summary":"Attackers can bypass certificate revocation checks in BIG-IP APM when CRL downloads fail, allowing revoked certificates to be treated as valid.","url":"https://insights.sbomify.com/CVE-2018-15326/"}
