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-2024-21771 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-2024-21771/ (Markdown: https://insights.sbomify.com/CVE-2024-21771/index.md)","id":"CVE-2024-21771","markdown":"https://insights.sbomify.com/CVE-2024-21771/index.md","name":"CVE-2024-21771","record":{"aliases":["GHSA-8gwr-pghr-44v9"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"F5 BIG-IP AFM","requires_auth":"none","summary":"Attackers can cause traffic disruption and TMM restarts in F5 BIG-IP AFM by triggering excessive signature matching time.","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-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"For unspecified traffic patterns, BIG-IP AFM IPS engine may spend an excessive amount of time matching the traffic against signatures, resulting in Traffic Management Microkernel (TMM) restarting and traffic disruption.  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":"F5 AFM Signature Matching Vulnerability","id":"CVE-2024-21771","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":"Privilege escalation in Intel(R) Advisor software","id":"CVE-2024-21772"},"packages":[],"prev":{"headline":"Privilege escalation in Intel(R) Ethernet Connection I219-LM install software","id":"CVE-2024-21769"},"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":"BIG-IP AFM vulnerability","id":"CVE-2024-21763","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":"2025-03-24","vendors":["F5"]},"summary":"Attackers can cause traffic disruption and TMM restarts in F5 BIG-IP AFM by triggering excessive signature matching time.","url":"https://insights.sbomify.com/CVE-2024-21771/"}
