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-2015-5262 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.httpcomponents:httpclient (Maven): affected all versions; fixed in 4.3.6\n- org.apache.httpcomponents:httpclient (Maven): affected all versions; fixed in 4.3.6\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-2015-5262/ (Markdown: https://insights.sbomify.com/CVE-2015-5262/index.md)","id":"CVE-2015-5262","markdown":"https://insights.sbomify.com/CVE-2015-5262/index.md","name":"CVE-2015-5262","record":{"aliases":["CLSA-2026-1791370172","CLSA-2026-1791898676","DEBIAN-CVE-2015-5262","DLA-322-1","GHSA-fmj5-wv96-r2ch","MGASA-2015-0392","UBUNTU-CVE-2015-5262"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java HTTP client library","requires_auth":"none","summary":"Remote attackers can cause a denial of service by hanging HTTPS calls due to ignored socket timeouts during SSL handshakes in Apache HttpComponents HttpClient.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"httpclient","vendor":"apache"},{"product":"ubuntu_linux","vendor":"canonical"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"http/conn/ssl/SSLConnectionSocketFactory.java in Apache HttpComponents HttpClient before 4.3.6 ignores the http.socket.timeout configuration setting during an SSL handshake, which allows remote attackers to cause a denial of service (HTTPS call hang) via unspecified vectors.","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 vulnerability in org.apache.httpcomponents:httpclient","id":"CVE-2015-5262","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","fedoraproject:fedora"],"type":"denial_of_service","year":"2015"},"n_packages":2,"n_references":15,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2015-5263"},"packages":[{"ecosystem":"Maven","fixed":["4.3.6"],"introduced":["0"],"last_affected":[],"package":"org.apache.httpcomponents:httpclient","purl":null,"source":"GHSA-fmj5-wv96-r2ch"},{"ecosystem":"Maven","fixed":["4.3.6"],"introduced":["0"],"last_affected":[],"package":"org.apache.httpcomponents:httpclient","purl":"pkg:maven/org.apache.httpcomponents/httpclient","source":"GHSA-fmj5-wv96-r2ch"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2015-5261"},"products":["n/a"],"published":"2015-10-27","related":[{"cvss_score":9.8,"headline":"Hostname verification in Apache HttpClient 4.3 was disabled by default","id":"CVE-2013-4366","kev_date_added":null,"published":"2017-10-30"},{"cvss_score":9.1,"headline":"Apache HttpComponents Client: TLS hostname verification silently disabled on the async transport (default config, MITM)","id":"CVE-2026-71290","kev_date_added":null,"published":"2026-08-11"},{"cvss_score":7.5,"headline":"Apache HttpComponents: PSL (Public Suffix List) validation bypass","id":"CVE-2025-27820","kev_date_added":null,"published":"2025-04-24"},{"cvss_score":7.3,"headline":"Apache HttpClient accepts SCRAM-SHA-256 authentication without proper mutual authentication verification","id":"CVE-2026-40542","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":5.8,"headline":"Improper Certificate Validation in Apache Commons HttpClient","id":"CVE-2012-5783","kev_date_added":null,"published":"2012-11-04"},{"cvss_score":5.3,"headline":"Apache HttpComponents Client: Connection Leak on Content-Encoding Decode Error Leads to Pool Exhaustion DoS","id":"CVE-2026-64607","kev_date_added":null,"published":"2026-07-31"},{"cvss_score":5.3,"headline":"Cross-site scripting in Apache HttpClient","id":"CVE-2020-13956","kev_date_added":null,"published":"2020-12-02"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service by hanging HTTPS calls due to ignored socket timeouts during SSL handshakes in Apache HttpComponents HttpClient.","url":"https://insights.sbomify.com/CVE-2015-5262/"}
