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-2015-4638 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-2015-4638/ (Markdown: https://insights.sbomify.com/CVE-2015-4638/index.md)","id":"CVE-2015-4638","markdown":"https://insights.sbomify.com/CVE-2015-4638/index.md","name":"CVE-2015-4638","record":{"aliases":["GHSA-72v7-922f-7x9p"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"F5 BIG-IP load balancer","requires_auth":"none","summary":"Remote attackers can cause a denial of service by sending fragmented packets to the FastL4 virtual server, requiring administrators to apply vendor patches.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"big-ip_advanced_firewall_manager","vendor":"f5"},{"product":"big-ip_analytics","vendor":"f5"},{"product":"big-ip_application_security_manager","vendor":"f5"},{"product":"big-ip_edge_gateway","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":"big-ip_protocol_security_module","vendor":"f5"},{"product":"big-ip_webaccelerator","vendor":"f5"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The FastL4 virtual server in F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, GTM, Link Controller, and PEM 11.3.0 through 11.5.2 and 11.6.0 through 11.6.0 HF4, BIG-IP Edge Gateway, WebAccelerator, and WOM 11.2.1 through 11.3.0, and BIG-IP PSM 11.2.1 through 11.4.1 allows remote attackers to cause a denial of service (Traffic Management Microkernel restart) via a fragmented packet.","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":"Denial of service in n/a","id":"CVE-2015-4638","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"f5:big-ip_advanced_firewall_manager","products":["f5:big-ip_advanced_firewall_manager","f5:big-ip_analytics","f5:big-ip_application_security_manager","f5:big-ip_edge_gateway","f5:big-ip_global_traffic_manager","f5:big-ip_link_controller","f5:big-ip_local_traffic_manager","f5:big-ip_policy_enforcement_manager","f5:big-ip_protocol_security_module","f5:big-ip_webaccelerator"],"type":"denial_of_service","year":"2015"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2015-4639"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2015-4637"},"products":["n/a"],"published":"2015-09-18","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":"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service by sending fragmented packets to the FastL4 virtual server, requiring administrators to apply vendor patches.","url":"https://insights.sbomify.com/CVE-2015-4638/"}
