An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-46445 exists.\n\nAffected packages and fixed versions:\n- asyncssh (PyPI): affected all versions; fixed in 2.14.1\n- asyncssh (PyPI): affected all versions; fixed in 2.14.1\n- asyncssh (PyPI): affected all versions; fixed in 2.14.1\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-2023-46445/ (Markdown: https://insights.sbomify.com/CVE-2023-46445/index.md)","id":"CVE-2023-46445","markdown":"https://insights.sbomify.com/CVE-2023-46445/index.md","name":"CVE-2023-46445","record":{"aliases":["DEBIAN-CVE-2023-46445","GHSA-cfc2-wr2v-gxm5","PYSEC-2023-237","UBUNTU-CVE-2023-46445","openSUSE-SU-2024:13417-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Python SSH library","requires_auth":"none","summary":"Attackers can bypass SSH extension negotiation security checks via man-in-the-middle attacks in AsyncSSH, requiring library upgrades.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"asyncssh","vendor":"asyncssh_project"}],"cvss":{"score":5.9,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"An issue in AsyncSSH before 2.14.1 allows attackers to control the extension info message (RFC 8308) via a man-in-the-middle attack, aka a \"Rogue Extension Negotiation.\"","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"AsyncSSH Rogue Extension Negotiation","id":"CVE-2023-46445","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"security_feature_bypass","year":"2023"},"n_packages":3,"n_references":7,"next":{"headline":"AsyncSSH Rogue Session Attack","id":"CVE-2023-46446"},"packages":[{"ecosystem":"PyPI","fixed":["2.14.1"],"introduced":["0"],"last_affected":[],"package":"asyncssh","purl":null,"source":"GHSA-cfc2-wr2v-gxm5"},{"ecosystem":"PyPI","fixed":["2.14.1"],"introduced":["0"],"last_affected":[],"package":"asyncssh","purl":"pkg:pypi/asyncssh","source":"GHSA-cfc2-wr2v-gxm5"},{"ecosystem":"PyPI","fixed":["2.14.1"],"introduced":["0"],"last_affected":[],"package":"asyncssh","purl":"pkg:pypi/asyncssh","source":"PYSEC-2023-237"}],"prev":{"headline":"Soot Infinite Loop vulnerability","id":"CVE-2023-46442"},"products":["n/a"],"published":"2023-11-14","related":[{"cvss_score":9.8,"headline":"AsyncSSH SSH Server Authentication Bypass","id":"CVE-2018-7749","kev_date_added":null,"published":"2018-03-12"},{"cvss_score":8.2,"headline":"AsyncSSH `AuthorizedKeysFile %u` path traversal allows attacker-selected authorized keys to authenticate a traversal username","id":"CVE-2026-45309","kev_date_added":null,"published":"2026-07-17"},{"cvss_score":6.8,"headline":"AsyncSSH Rogue Session Attack","id":"CVE-2023-46446","kev_date_added":null,"published":"2023-11-14"}],"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":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-02-25","vendors":["n/a"]},"summary":"Attackers can bypass SSH extension negotiation security checks via man-in-the-middle attacks in AsyncSSH, requiring library upgrades.","url":"https://insights.sbomify.com/CVE-2023-46445/"}
