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-2021-22992 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-2021-22992/ (Markdown: https://insights.sbomify.com/CVE-2021-22992/index.md)","id":"CVE-2021-22992","markdown":"https://insights.sbomify.com/CVE-2021-22992/index.md","name":"CVE-2021-22992","record":{"aliases":["GHSA-4f8p-5r29-jr72"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"F5 BIG-IP WAF","requires_auth":"none","summary":"A buffer overflow in F5 BIG-IP Advanced WAF/ASM allows remote attackers to cause denial of service or execute arbitrary code via malicious HTTP responses.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"f5","cpe":[{"product":"big-ip_access_policy_manager","vendor":"f5"},{"product":"big-ip_advanced_firewall_manager","vendor":"f5"},{"product":"big-ip_advanced_web_application_firewall","vendor":"f5"},{"product":"big-ip_analytics","vendor":"f5"},{"product":"big-ip_application_acceleration_manager","vendor":"f5"},{"product":"big-ip_application_security_manager","vendor":"f5"},{"product":"big-ip_ddos_hybrid_defender","vendor":"f5"},{"product":"big-ip_domain_name_system","vendor":"f5"},{"product":"big-ip_fraud_protection_service","vendor":"f5"},{"product":"big-ip_global_traffic_manager","vendor":"f5"},{"product":"big-ip_link_controller","vendor":"f5"},{"product":"big-ip_local_traffic_manager","vendor":"f5"},{"product":"big-ip_policy_enforcement_manager","vendor":"f5"},{"product":"ssl_orchestrator","vendor":"f5"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"On BIG-IP versions 16.0.x before 16.0.1.1, 15.1.x before 15.1.2.1, 14.1.x before 14.1.4, 13.1.x before 13.1.3.6, 12.1.x before 12.1.5.3, and 11.6.x before 11.6.5.3, a malicious HTTP response to an Advanced WAF/BIG-IP ASM virtual server with Login Page configured in its policy may trigger a buffer overflow, resulting in a DoS attack.
