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-2011-4905 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.activemq:activemq-core (Maven): affected all versions; fixed in 5.6.0\n- org.apache.activemq:activemq-core (Maven): affected all versions; fixed in 5.6.0\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-2011-4905/ (Markdown: https://insights.sbomify.com/CVE-2011-4905/index.md)","id":"CVE-2011-4905","markdown":"https://insights.sbomify.com/CVE-2011-4905/index.md","name":"CVE-2011-4905","record":{"aliases":["DEBIAN-CVE-2011-4905","GHSA-9wcx-326r-7j7w"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache ActiveMQ","requires_auth":"none","summary":"Remote attackers can crash or hang Apache ActiveMQ brokers by exhausting file descriptors via repeated failover connection requests.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"activemq","vendor":"apache"}],"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-399","name":null}],"description":"Apache ActiveMQ before 5.6.0 allows remote attackers to cause a denial of service (file-descriptor exhaustion and broker crash or hang) by sending many openwire failover:tcp:// connection requests.","ecosystems":["Maven"],"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":"Denial of Service in Apache ActiveMQ","id":"CVE-2011-4905","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"apache:activemq","products":["apache:activemq"],"type":"denial_of_service","year":"2011"},"n_packages":2,"n_references":7,"next":{"headline":"File upload in Tiny browser included with TinyMCE 3.0","id":"CVE-2011-4906"},"packages":[{"ecosystem":"Maven","fixed":["5.6.0"],"introduced":["0"],"last_affected":[],"package":"org.apache.activemq:activemq-core","purl":null,"source":"GHSA-9wcx-326r-7j7w"},{"ecosystem":"Maven","fixed":["5.6.0"],"introduced":["0"],"last_affected":[],"package":"org.apache.activemq:activemq-core","purl":"pkg:maven/org.apache.activemq/activemq-core","source":"GHSA-9wcx-326r-7j7w"}],"prev":{"headline":"Typo3 Improper Access Control","id":"CVE-2011-4904"},"products":["n/a"],"published":"2012-01-05","related":[{"cvss_score":10,"headline":"Apache ActiveMQ Deserialization of Untrusted Data","id":"CVE-2023-46604","kev_date_added":"2023-11-02","published":"2023-10-27"},{"cvss_score":9.8,"headline":"Apache ActiveMQ Improper Input Validation","id":"CVE-2016-3088","kev_date_added":"2022-02-10","published":"2016-06-01"},{"cvss_score":8.8,"headline":"Apache ActiveMQ Improper Input Validation","id":"CVE-2026-34197","kev_date_added":"2026-04-16","published":"2026-04-07"},{"cvss_score":9.8,"headline":"Remote code execution in Apache ActiveMQ","id":"CVE-2020-11998","kev_date_added":null,"published":"2020-09-10"},{"cvss_score":9.8,"headline":"Command Injection in Xstream","id":"CVE-2013-7285","kev_date_added":null,"published":"2019-05-15"},{"cvss_score":9.8,"headline":"Improper Restriction of XML External Entity Reference in Apache ActiveMQ","id":"CVE-2014-3600","kev_date_added":null,"published":"2017-10-27"},{"cvss_score":9.8,"headline":"Improper Input Validation in Apache ActiveMQ","id":"CVE-2015-5254","kev_date_added":null,"published":"2016-01-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can crash or hang Apache ActiveMQ brokers by exhausting file descriptors via repeated failover connection requests.","url":"https://insights.sbomify.com/CVE-2011-4905/"}
