Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-12610 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.kafka:kafka-clients (Maven): affected from 0.10.0.0; fixed in 0.10.2.2\n- org.apache.kafka:kafka-clients (Maven): affected from 0.10.0.0; fixed in 0.10.2.2\n- org.apache.kafka:kafka-clients (Maven): affected from 0.11.0.0; fixed in 0.11.0.2\n- org.apache.kafka:kafka-clients (Maven): affected from 0.11.0.0; fixed in 0.11.0.2\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-2017-12610/ (Markdown: https://insights.sbomify.com/CVE-2017-12610/index.md)","id":"CVE-2017-12610","markdown":"https://insights.sbomify.com/CVE-2017-12610/index.md","name":"CVE-2017-12610","record":{"aliases":["GHSA-xm78-4m3g-7wm7"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Kafka","requires_auth":"low_privilege","summary":"Authenticated clients can impersonate other users via crafted protocol messages in Apache Kafka's SASL implementations, leading to unauthorized access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"kafka","vendor":"apache"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"In Apache Kafka 0.10.0.0 to 0.10.2.1 and 0.11.0.0 to 0.11.0.1, authenticated Kafka clients may use impersonation via a manually crafted protocol message with SASL/PLAIN or SASL/SCRAM authentication when using the built-in PLAIN or SCRAM server implementations in Apache Kafka.","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":"Improper Authentication in Apache Kafka","id":"CVE-2017-12610","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"auth_bypass","year":"2017"},"n_packages":4,"n_references":6,"next":{"headline":"Apache Struts 2.0.1 uses an unintentional expression in a Freemarker tag instead of string literal","id":"CVE-2017-12611"},"packages":[{"ecosystem":"Maven","fixed":["0.10.2.2"],"introduced":["0.10.0.0"],"last_affected":[],"package":"org.apache.kafka:kafka-clients","purl":null,"source":"GHSA-xm78-4m3g-7wm7"},{"ecosystem":"Maven","fixed":["0.10.2.2"],"introduced":["0.10.0.0"],"last_affected":[],"package":"org.apache.kafka:kafka-clients","purl":"pkg:maven/org.apache.kafka/kafka-clients","source":"GHSA-xm78-4m3g-7wm7"},{"ecosystem":"Maven","fixed":["0.11.0.2"],"introduced":["0.11.0.0"],"last_affected":[],"package":"org.apache.kafka:kafka-clients","purl":null,"source":"GHSA-xm78-4m3g-7wm7"},{"ecosystem":"Maven","fixed":["0.11.0.2"],"introduced":["0.11.0.0"],"last_affected":[],"package":"org.apache.kafka:kafka-clients","purl":"pkg:maven/org.apache.kafka/kafka-clients","source":"GHSA-xm78-4m3g-7wm7"}],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2017-12609"},"products":["Apache Kafka"],"published":"2018-07-26","related":[{"cvss_score":9.1,"headline":"Apache Kafka: Missing JWT token validation in OAUTHBEARER authentication","id":"CVE-2026-33557","kev_date_added":null,"published":"2026-04-20"},{"cvss_score":8.8,"headline":"Apache Kafka: Possible RCE attack via SASL JAAS LdapLoginModule configuration","id":"CVE-2025-27818","kev_date_added":null,"published":"2025-06-10"},{"cvss_score":8.8,"headline":"Improper Input Validation in Apache Kafka","id":"CVE-2018-17196","kev_date_added":null,"published":"2019-07-11"},{"cvss_score":8.7,"headline":"Apache Kafka Clients: Kafka Producer Message Corruption and Misrouting via Buffer Pool Race Condition","id":"CVE-2026-35554","kev_date_added":null,"published":"2026-04-07"},{"cvss_score":7.5,"headline":"Apache Kafka Client: Arbitrary file read and SSRF vulnerability","id":"CVE-2025-27817","kev_date_added":null,"published":"2025-06-10"},{"cvss_score":7.5,"headline":"Apache Kafka: Possible RCE/Denial of service attack via SASL JAAS JndiLoginModule configuration","id":"CVE-2025-27819","kev_date_added":null,"published":"2025-06-10"},{"cvss_score":7.5,"headline":"Unauthenticated clients may cause OutOfMemoryError on Apache Kafka Brokers","id":"CVE-2022-34917","kev_date_added":null,"published":"2022-09-20"}],"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":"2024-09-17","vendors":["Apache Software Foundation"]},"summary":"Authenticated clients can impersonate other users via crafted protocol messages in Apache Kafka's SASL implementations, leading to unauthorized access.","url":"https://insights.sbomify.com/CVE-2017-12610/"}
