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-2024-21763 in the wild and no public exploit code.\n\nAffected product: F5 Big-Ip Advanced Firewall 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-2024-21763/ (Markdown: https://insights.sbomify.com/CVE-2024-21763/index.md)","id":"CVE-2024-21763","markdown":"https://insights.sbomify.com/CVE-2024-21763/index.md","name":"CVE-2024-21763","record":{"aliases":["GHSA-v8xr-rghj-pvv9"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"BIG-IP AFM","requires_auth":"none","summary":"Attackers can cause TMM termination via undisclosed queries when AFM DoS profiles with NXDOMAIN detection are configured, requiring an upgrade.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"f5","cpe":[{"product":"big-ip_advanced_firewall_manager","vendor":"f5"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"When BIG-IP AFM Device DoS or DoS profile is configured with NXDOMAIN attack vector and bad actor detection, undisclosed queries can cause the Traffic Management Microkernel (TMM) to terminate.  NOTE: Software versions which have reached End of Technical Support (EoTS) are not evaluated","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":"BIG-IP AFM vulnerability","id":"CVE-2024-21763","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"f5:big-ip_advanced_firewall_manager","products":["f5:big-ip_advanced_firewall_manager"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Use of Hard-Coded Credentials in Rapid SCADA","id":"CVE-2024-21764"},"packages":[],"prev":{"headline":"Fortinet FortiOS Out-of-Bound Write","id":"CVE-2024-21762"},"products":["BIG-IP"],"published":"2024-02-14","related":[{"cvss_score":8.8,"headline":"SQL injection in BIG-IP AFM","id":"CVE-2021-23040","kev_date_added":null,"published":"2021-09-14"},{"cvss_score":8.7,"headline":"BIG-IP AFM DoS protection profile vulnerability","id":"CVE-2025-59478","kev_date_added":null,"published":"2025-10-15"},{"cvss_score":8.7,"headline":"BIG-IP AFM vulnerability","id":"CVE-2025-24312","kev_date_added":null,"published":"2025-02-05"},{"cvss_score":8.4,"headline":"Cross-site scripting in BIG-IP (AFM, ASM)","id":"CVE-2019-6636","kev_date_added":null,"published":"2019-07-03"},{"cvss_score":7.5,"headline":"F5 AFM Signature Matching Vulnerability","id":"CVE-2024-21771","kev_date_added":null,"published":"2024-02-14"},{"cvss_score":7.5,"headline":"BIG-IP AFM vulnerability","id":"CVE-2023-22281","kev_date_added":null,"published":"2023-02-01"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-06","vendors":["F5"]},"summary":"Attackers can cause TMM termination via undisclosed queries when AFM DoS profiles with NXDOMAIN detection are configured, requiring an upgrade.","url":"https://insights.sbomify.com/CVE-2024-21763/"}
