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-2011-3188 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-2011-3188/ (Markdown: https://insights.sbomify.com/CVE-2011-3188/index.md)","id":"CVE-2011-3188","markdown":"https://insights.sbomify.com/CVE-2011-3188/index.md","name":"CVE-2011-3188","record":{"aliases":["GHSA-93rr-wh56-p8fw"],"analysis":{"component_type":"kernel","fix_type":"upgrade","impacts":["denial_of_service","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel networking","requires_auth":"none","summary":"Remote attackers can disrupt networking or hijack sessions by predicting weak IPv4/IPv6 sequence numbers generated by the Linux kernel.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"arx","vendor":"f5"},{"product":"big-ip_access_policy_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_protocol_security_module","vendor":"f5"},{"product":"big-ip_wan_optimization_manager","vendor":"f5"},{"product":"big-ip_webaccelerator","vendor":"f5"},{"product":"enterprise_manager","vendor":"f5"},{"product":"firepass","vendor":"f5"},{"product":"linux_kernel","vendor":"linux"},{"product":"enterprise_linux","vendor":"redhat"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[],"description":"The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorithm to generate sequence numbers and Fragment Identification values, which makes it easier for remote attackers to cause a denial of service (disrupted networking) or hijack network sessions by predicting these values and sending crafted packets.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Other in n/a","id":"CVE-2011-3188","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"f5:big-ip_access_policy_manager","products":["f5:big-ip_access_policy_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_protocol_security_module","f5:big-ip_webaccelerator","linux:linux_kernel","redhat:enterprise_linux"],"type":"other","year":"2011"},"n_packages":0,"n_references":9,"next":{"headline":"Auth bypass in n/a","id":"CVE-2011-3189"},"packages":[],"prev":{"headline":"actionpack Improper Input Validation vulnerability","id":"CVE-2011-3187"},"products":["n/a"],"published":"2012-05-24","related":[{"cvss_score":9.3,"headline":"Auth bypass in n/a","id":"CVE-2014-2927","kev_date_added":null,"published":"2014-10-15"},{"cvss_score":5.9,"headline":"Information disclosure in HTTPS protocol","id":"CVE-2013-3587","kev_date_added":null,"published":"2020-02-21"}],"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":"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 disrupt networking or hijack sessions by predicting weak IPv4/IPv6 sequence numbers generated by the Linux kernel.","url":"https://insights.sbomify.com/CVE-2011-3188/"}
