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-2024-21789 in the wild and no public exploit code.\n\nAffected product: F5 Big-Ip Advanced Web Application Firewall. 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-2024-21789/ (Markdown: https://insights.sbomify.com/CVE-2024-21789/index.md)","id":"CVE-2024-21789","markdown":"https://insights.sbomify.com/CVE-2024-21789/index.md","name":"CVE-2024-21789","record":{"aliases":["GHSA-qq56-5xwp-c89r"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"BIG-IP ASM WAF","requires_auth":"none","summary":"Attackers can cause memory exhaustion and denial of service on F5 BIG-IP ASM/Advanced WAF when specific security policies are configured.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"f5","cpe":[{"product":"big-ip_advanced_web_application_firewall","vendor":"f5"},{"product":"big-ip_application_security_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-772","name":"Missing Release of Resource after Effective Lifetime"}],"description":"When a BIG-IP ASM/Advanced WAF security policy is configured on a virtual server, undisclosed requests can cause an increase in memory resource utilization.\n 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 ASM and Advanced WAF vulnerability","id":"CVE-2024-21789","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"f5:big-ip_advanced_web_application_firewall","products":["f5:big-ip_advanced_web_application_firewall","f5:big-ip_application_security_manager"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"SQL Injection in ADAudit Plus","id":"CVE-2024-21791"},"packages":[],"prev":{"headline":"Privilege escalation in Intel(R) GPA software","id":"CVE-2024-21788"},"products":["BIG-IP"],"published":"2024-02-14","related":[{"cvss_score":9.9,"headline":"Privilege escalation in BIG-IP Advanced WAF and BIG-IP ASM","id":"CVE-2021-23031","kev_date_added":null,"published":"2021-09-14"},{"cvss_score":8.8,"headline":"Server-side request forgery in BIG-IP Advanced WAF and BIG-IP ASM","id":"CVE-2021-23029","kev_date_added":null,"published":"2021-09-14"},{"cvss_score":8.8,"headline":"Missing authorization in BIG-IP ASM/Advanced WAF","id":"CVE-2021-23014","kev_date_added":null,"published":"2021-05-10"},{"cvss_score":8.8,"headline":"Cross-site scripting in BIG-IP Advanced WAF and BIG-IP ASM","id":"CVE-2021-22993","kev_date_added":null,"published":"2021-03-31"},{"cvss_score":8.7,"headline":"BIG-IP Advanced WAF and ASM vulnerability","id":"CVE-2026-40060","kev_date_added":null,"published":"2026-05-13"},{"cvss_score":8.7,"headline":"BIG-IP HTTP/2 Layer 7 Dos Protection vulnerability","id":"CVE-2026-41227","kev_date_added":null,"published":"2026-05-13"},{"cvss_score":8.7,"headline":"BIG-IP Advanced WAF and ASM vulnerability","id":"CVE-2025-54858","kev_date_added":null,"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-24","vendors":["F5"]},"summary":"Attackers can cause memory exhaustion and denial of service on F5 BIG-IP ASM/Advanced WAF when specific security policies are configured.","url":"https://insights.sbomify.com/CVE-2024-21789/"}
