An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2018-15319 and fix it if it is affected.\n\nWhat it is: CVE-2018-15319 is a high-severity denial of service vulnerability in F5 Big-Ip Access Policy Manager, published on 31 Oct 2018. 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-2018-15319 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-2018-15319/ (Markdown: https://insights.sbomify.com/CVE-2018-15319/index.md)","id":"CVE-2018-15319","markdown":"https://insights.sbomify.com/CVE-2018-15319/index.md","name":"CVE-2018-15319","record":{"aliases":["GHSA-prgq-gfv9-v386"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"F5 BIG-IP","requires_auth":"none","summary":"Malicious HTTP requests can crash the Traffic Management Microkernel, causing a denial of service on F5 BIG-IP devices with specific non-default configurations.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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_analytics","vendor":"f5"},{"product":"big-ip_application_acceleration_manager","vendor":"f5"},{"product":"big-ip_domain_name_system","vendor":"f5"},{"product":"big-ip_edge_gateway","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":"big-ip_protocol_security_module","vendor":"f5"},{"product":"big-ip_webaccelerator","vendor":"f5"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"On BIG-IP 14.0.0-14.0.0.2, 13.0.0-13.1.1.1, or 12.1.0-12.1.3.6, malicious requests made to virtual servers with an HTTP profile can cause the TMM to restart.
