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-2023-46853 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- memcached (Bitnami): affected all versions; fixed in 1.6.22\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-2023-46853/ (Markdown: https://insights.sbomify.com/CVE-2023-46853/index.md)","id":"CVE-2023-46853","markdown":"https://insights.sbomify.com/CVE-2023-46853/index.md","name":"CVE-2023-46853","record":{"aliases":["AZL-31732","AZL-34977","BIT-memcached-2023-46853","DEBIAN-CVE-2023-46853","GHSA-jr2m-hrp3-3wj4","ROOT-OS-ALPINE-317-CVE-2023-46853","ROOT-OS-ALPINE-318-CVE-2023-46853","UBUNTU-CVE-2023-46853"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Memcached server","requires_auth":"none","summary":"An off-by-one error in Memcached proxy mode allows attackers to cause memory corruption, potentially leading to crashes or code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"memcached","vendor":"memcached"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-193","name":"Off-by-one Error"}],"description":"In Memcached before 1.6.22, an off-by-one error exists when processing proxy requests in proxy mode, if \\n is used instead of \\r\\n.","ecosystems":["Bitnami"],"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":"Memory corruption in n/a","id":"CVE-2023-46853","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":1,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2023-46854"},"packages":[{"ecosystem":"Bitnami","fixed":["1.6.22"],"introduced":["0"],"last_affected":[],"package":"memcached","purl":"pkg:bitnami/memcached","source":"BIT-memcached-2023-46853"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2023-46852"},"products":["n/a"],"published":"2023-10-27","related":[{"cvss_score":9.8,"headline":"Integer overflow in Memcached","id":"CVE-2016-8704","kev_date_added":null,"published":"2017-01-06"},{"cvss_score":9.8,"headline":"Integer overflow in Memcached","id":"CVE-2016-8705","kev_date_added":null,"published":"2017-01-06"},{"cvss_score":8.1,"headline":"Information disclosure in memcached","id":"CVE-2026-47783","kev_date_added":null,"published":"2026-05-20"},{"cvss_score":8.1,"headline":"Information disclosure in memcached","id":"CVE-2026-47784","kev_date_added":null,"published":"2026-05-20"},{"cvss_score":8.1,"headline":"Integer overflow in Memcached","id":"CVE-2016-8706","kev_date_added":null,"published":"2017-01-06"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2023-46852","kev_date_added":null,"published":"2023-10-27"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-09-09","vendors":["n/a"]},"summary":"An off-by-one error in Memcached proxy mode allows attackers to cause memory corruption, potentially leading to crashes or code execution.","url":"https://insights.sbomify.com/CVE-2023-46853/"}
