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-2015-5600 in the wild and no public exploit code.\n\nAffected product: OpenSSH. 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-2015-5600/ (Markdown: https://insights.sbomify.com/CVE-2015-5600/index.md)","id":"CVE-2015-5600","markdown":"https://insights.sbomify.com/CVE-2015-5600/index.md","name":"CVE-2015-5600","record":{"aliases":["DEBIAN-CVE-2015-5600","GHSA-6x25-gfx2-5crp","MGASA-2015-0295","UBUNTU-CVE-2015-5600"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenSSH server","requires_auth":"none","summary":"Remote attackers can cause CPU exhaustion and facilitate brute-force attacks by sending a duplicative keyboard-interactive device list to OpenSSH.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"openssh","vendor":"openbsd"}],"cvss":{"score":8.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-264","name":null},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"The kbdint_next_device function in auth2-chall.c in sshd in OpenSSH through 6.9 does not properly restrict the processing of keyboard-interactive devices within a single connection, which makes it easier for remote attackers to conduct brute-force attacks or cause a denial of service (CPU consumption) via a long and duplicative list in the ssh -oKbdInteractiveDevices option, as demonstrated by a modified client that provides a different password for each pam element on this list.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-11-11","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-11-11T10:00:43Z","kind":"github_poc","ref":"https://github.com/Abdirisaq-ali-aynab/vulnerability-assessment","stars":0,"title":"Professional cybersecurity assessment demonstrating vulnerability identification, CVSS severity scoring, MITRE ATT\u0026CK framework application, and detailed remediation planning for OpenSSH 6.6.1p1 critical vulnerabilities (CVE-2016-0777, CVE-2015-5600)"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2015-5600","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"openbsd:openssh","products":["openbsd:openssh"],"type":"denial_of_service","year":"2015"},"n_packages":0,"n_references":33,"next":{"headline":"File upload in n/a","id":"CVE-2015-5601"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2015-5599"},"products":["n/a"],"published":"2015-08-03","related":[{"cvss_score":10,"headline":"Auth bypass in n/a","id":"CVE-2003-0786","kev_date_added":null,"published":"2003-09-25"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2003-0693","kev_date_added":null,"published":"2003-09-17"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2002-0640","kev_date_added":null,"published":"2003-04-02"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2001-0144","kev_date_added":null,"published":"2001-05-07"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2000-0999","kev_date_added":null,"published":"2000-11-29"},{"cvss_score":10,"headline":"Privilege escalation in n/a","id":"CVE-2000-0525","kev_date_added":null,"published":"2000-10-13"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2010-4478","kev_date_added":null,"published":"2010-12-06"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-27","vendors":["n/a"]},"summary":"Remote attackers can cause CPU exhaustion and facilitate brute-force attacks by sending a duplicative keyboard-interactive device list to OpenSSH.","url":"https://insights.sbomify.com/CVE-2015-5600/"}
